Plagiarism Checker FAQ

What is plagiarism.

Plagiarism is the act of representing someone else’s work as your own. In educational contexts, definitions vary by institution. It includes direct copying, improper paraphrasing, and self-plagiarism, where one reuses their own work without citation. Plagiarism violates academic integrity and journalistic ethics. In academic writing, producing original work and appropriately crediting sources prevents plagiarized content. Accidental plagiarism occurs when sources are unintentionally cited incorrectly, underscoring the importance of understanding citation practices. Maintaining originality and avoiding plagiarism not only uphold academic integrity but also contribute to creating original content that advances knowledge and scholarship.

What percentage of a paper can be plagiarized (or copied) and still be considered unique?

Generally speaking, similar or exact copies of another source should be kept under 15% for the total text of the article/paper/essay. As a best practice, citations should be used whenever using another original source word-for-word.

What’s the difference between deliberate and accidental plagiarism?

Deliberate plagiarism is purposely copying works from books, articles, webpages, or someone else’s paper and representing it as your original work. Alternatively, accidental plagiarism occurs in a few different ways:

• Incorrectly citing another person’s works
• Failing to paraphrase another person’s works - even when citing it correctly
• Reusing your own previous papers and inadvertently representing it as a new idea

A plagiarism checker works by comparing the submitted copy against known existing content. This sort of similarity checker flags instances of duplicate content, allowing the writer to modify those areas to avoid any claims of plagiarism.

What are the consequences of plagiarism?

The consequences of plagiarizing another person’s work vary by profession. For Students: Maintaining academic integrity is crucial. Students must ensure their work is not plagiarized. Consequences include failing grades, removal from classes, or expulsion. Even if allowed to stay, students may face mistrust and scrutiny. For Copywriters: Copywriters must produce original content. Plagiarized content can damage their reputation and make it hard to get assignments. Ensuring 100% originality is their responsibility. For Journalists: Journalists must uphold high standards of integrity. Plagiarized content erodes trust with readers and publishers, potentially ending careers. They must produce original, well-cited content.

Why is plagiarism bad?

There are several reasons why plagiarism is wrong, all centering around violating academic integrity, undermining originality, and eroding trust. It leads to legal consequences, tarnishes reputations, and stunts personal growth. Avoiding plagiarism preserves credibility, fosters creativity, and upholds ethical standards. Educational institutions and search engines penalize plagiarized content, impacting SEO rankings and visibility. Embracing originality ensures sustainable success and fosters a trustworthy reputation online.

Can AI-generated content be considered plagiarism-free?

AI-generated content, such as text produced by language models like GPT-3, GPT-4, and Gemini, can be considered plagiarism-free if properly used and cited. However, using AI writing tools like ChatGPT without adequate citation can lead to unintentional plagiarism. It's vital to use an AI content detector to ensure originality. High-quality tools that use advanced detection models, like Quetext’s AI Detector, can help identify AI-generated text, minimizing the risk of false positives and ensuring that submissions are plagiarism-free.

How does AI technology impact plagiarism detection?

AI-generated content and AI-generated text are now common, making AI content detection crucial. Detecting AI technology, including advanced algorithms and language models like ChatGPT-3 and GPT-4, has significantly improved plagiarism detection. Tools like Quetext’s AI detector tool utilize these advanced models to compare submitted text against vast databases, ensuring accurate detection of potential plagiarism and copy written by artificial intelligence or generative ai.

Once they leave the institution, all those students lose the ability to create original content because they have only cheated before.

Professional

Countless journalists, academics, writers, and creators have had their reputations damaged by plagiarism accusations.

Free plagiarism checker for you to enjoy

Essay plagiarism checker free with accurate percentage.

When dealing with an academic task, a student often needs to check essay for plagiarism before submitting it to their professor. Many colleges and high schools set a certain limit on plagiarised content in essays, research papers, theses, and other academic papers. So, it's crucial to know the exact percentage of unique content to avoid any issues with your educator.

Unfortunately, a typical plagiarism checker free for students doesn't show the precise ratio of the original text in an essay. It simply states whether the whole text has any traces of plagiarism. This is utterly misleading and unhelpful. Even the simplest citation will make your text not 100% original, not to mention improper quotes and self-plagiarism. So, you'll be left with only one choice - to rewrite your essay from scratch in an attempt to get fully original content. Considering how complex and lengthy formatting rules for scholars are, crafting a 100% unique text without making a single citation or self-plagiarism mistake becomes a nearly impossible task.

Are there consequences for using free plagiarism checkers?

Plagiarism is the act of copying someone else's work without proper attribution, whether intentional or not.

Even minor paraphrasing can result in lower grades and other severe consequences, such as expulsion from school or even damaging one's professional reputation.

It is crucial to understand the principles of academic integrity and honesty and to always check your work for plagiarism. This is especially important for students working on dissertations, theses, or other significant academic projects that require original research.

A Grammar Check for Peace of Mind

You know that grammar plays a significant role in your assignments. Not only does it factor into your overall grade, but without clear and precise language, your ideas can lose their impact or might even be misunderstood entirely. Still, with so many different parts of speech and rules to learn and apply, it’s not uncommon to get them mixed up and find yourself questioning your knowledge now and again:

Can you use an adverb to modify a noun? (No. You need an adjective for that.)

Well, can you use it to modify a pronoun ? (Still no.)

What do they modify, then? (Almost everything else. Fun, right?)

Ugh. (That was an interjection .)

Why is Grammar So Important, Anyway?

Why is grammar important? As long as others know what you mean, does it really matter if you use proper grammar? These are age-old questions, but the answers remain unchanged. Grammar is important for many reasons:

Communication:  Communication is about more than merely listening and talking. We communicate in myriad ways: with our voices, our mannerisms, our facial expressions, our actions, and frequently, our written words. Written communication is just as important as all the other ways we broadcast our thoughts and feelings. Unlike our other communication methods, though, written communication leaves a record. While most of us relax our style when talking to or texting friends, the fact remains that more formal venues require a more formal tone. Proper spelling, grammar, and punctuation are a necessary element of professional and academic writing, so running your work through a spelling and grammar check before you submit it is an absolute must.

Clarity:  Expressing your thoughts, ideas, and opinions is an uphill battle when you communicate them with less-than-stellar punctuation, spelling, and grammar. A missing or misplaced comma, for example, can entirely change your meaning:

• Call me Ishmael = My name is Ishmael.
• Call me, Ishmael = I want Ishmael to call me.

Spelling errors can result in similarly muddled meaning:

• Her shoes perfectly complemented her dress. = Her shoes and dress go well together.
• Her shoes perfectly complimented her dress. = Her shoes can both speak and engage in flattery.

Grammar deficiencies such as a dangling modifier yield similarly confusing results:

• I saw the girl’s purple backpack in the library. = The purple backpack belonging to the girl is in the library; I saw it.
• I saw the purple girl’s backpack in the library. = You know the girl who mysteriously turned purple? I saw her backpack in the library. This week has not been easy on her.

Credibility: Establishing your credibility is critical whether you’re writing for school or business. Proving that you can reliably communicate using proper grammar is essential to establishing and maintaining the trust of your teachers, professors, readers, customers, and colleagues.

What Happens After I Upload My Paper?

Once you upload a paper, the EasyBib Plus grammar checker scans your text and highlights grammar issues within your document so you can see it in context. For users running a grammar check and spell check using the grammar check free tool, up to the first 5 issues are shown. For subscription subscribers, all of the areas that require your review will be highlighted once the scan is complete.

No matter which version of the tool you’re using, your feedback will include detailed explanations so you can understand why the text was flagged. Other highlighted areas will include examples of how the issues can be fixed. Some will include a detailed explanation as to why the issue was flagged. This personalized feedback allows you to make an educated decision about whether to edit your text or dismiss the suggestion, so you’re always in control of your final draft.

Subscription users also have the plagiarism checker at their disposal when scanning their papers for style and grammar suggestions. Just as with our other writing tools, when you use the tool to check plagiarism, changes are never made without your review, so you are always in the driver’s seat. You can review each highlighted area as well as the sources of matching text and will always be given a choice to either accept or ignore both citation and grammar suggestions.

Check for Unintentional Plagiarism

Persistent use of the best grammar checker and spell checker you can find will help to shape up the style and substance of your composition. However, to ensure the integrity of your work and root out unintentional instances of academic dishonesty, you’ll also need to incorporate a subscription-based or free plagiarism checker for students.

The ability to scan your paper and check plagiarism and grammar before submitting your work is an invaluable tool for students. It’s so valuable, in fact, that students are not the only ones who consistently use this type of software.

Many teachers and professors use a service to ensure that student papers are original and include properly formatted and sourced citations for all reference materials. For some, this may be a consistent element of their grading process, while others may utilize one only when they feel there is a reason to do so.

What Exactly Does a Plagiarism Checker Do?

If you’ve used an online plagiarism checker before, you may be familiar with the process that these tools employ. For those who have never used one, it can be helpful to understand how these tools work and what you should expect as a result of using one.

The most basic free tools will scan your paper and provide you with a percentage that indicates how much of your work is original. This feature can be useful to a point, as some instructors and institutions set a percentage for the amount of similar text that is considered acceptable. This policy does not mean that they are lenient about academic dishonesty but, instead, that they recognize that similar or even matching word choice is not always an indicator of copying.

However, some schools do not tolerate any form of incremental plagiarism, period. In these institutions, “check paper for plagiarism” is likely a standard action when grading all papers.

With a free plagiarism checker, the percentage of word-for-word plagiarism in your text may be the only feedback you receive. Moreover, some of these providers may wade in unethical waters, and offer essay writing services in conjunction with their checking services. This is why many students and teachers prefer subscription-based checkers that focus on integrity, such as the EasyBib writing tools.

With our premium tools, you get more than just supporting proof that your paper is original and in your own words. Your writing is scanned for potentially matching text and areas that needs your attention is highlighted. We’ll provide you with the source of the matching text so you can review it and decide how to proceed. If you agree that a citation is needed, our citation tools and resources will provide you with the information you need to help format and insert the new sources in your text as well as your works cited page.

How Does the EasyBib Plus Online Plagiarism Checker Work?

The EasyBib Plus writing tool provides an all-in-one spell check, grammar review, and plagiarism checker that not only helps you with the paper you’re writing now but enables you to gain new knowledge and improve your writing for the future, too.

Our essay checker searches online for phrases, sentences, or passages that are similar to those in your paper. If it returns matching text, this may indicate that you have passages that are missing citations.

Just as with many checkers, our tool will tell you how many instances of matching text it finds in your paper. Our plagiarism tool is designed to do more than most free tools, however.

When a portion of your paper is flagged for review, we provide you with the source that it matches. As with our online spell check tool, you have the power to review each area and choose how to proceed. If you decide to cite the flagged text, you can review the suggested source and access our citation tools to help create a proper citation and start building a bibliography for your paper. Or, you may determine that no citation is needed, in which case it’s simple to dismiss the suggestion and continue to the next section.

If you’re unsure about how to proceed, our library of resources can help you learn more and make an educated decision. In this way, you gain more than just the ability to correct your work; over time, you can learn how to avoid plagiarism altogether.

Reasons Your Teacher May Run Your Paper Through a Plagiarism Detector

As stated previously, your teachers and professors grade papers with a fixed process that includes “check paper for plagiarism” as a standard, across-the-board action. Others may check for plagiarism only when they feel there is cause to do so. There are a few red flags that may stand out to them while reviewing a paper that would lead to their running a plagiarism check, including:

Style/Voice:  Most teachers are familiar with the style and voice that you use in your writing. While most will hope that the feedback they provide when grading your work will help you to improve problem areas over time, a paper or essay that has a dramatically different style or voice than the work you’ve previously submitted can be a red flag.

Inconsistency:  Changes in the font, font size, formality, formatting, and more may indicate that portions of a paper have been copied and pasted. If these inconsistent passages are not presented as quotations or don’t include citations, this may further indicate to your teacher that there’s plagiarism in the paper.

Old References:  Part of a well-researched paper is verifying the legitimacy and relevance of your sources. While some older references may be acceptable depending on the topic, if all of your sources are outdated, it may lead your teacher to believe that you’ve recycled your own work or someone else’s.

What is Plagiarism?

If you’re looking for a free online plagiarism checker , you’re already aware that it’s not something you want to be found in your papers. However, you may still be wondering: what does plagiarism mean? It’s a reasonable question and one that merits exploring. After all, some of the actions and circumstances that fall within the plagiarism definition come as a surprise to those who only learn that they’ve committed them after it’s too late.

So what is plagiarism? To define plagiarism in the most basic sense, you might say that it is taking someone else’s ideas and words and passing them off as your own.

If your goal is avoiding plagiarism entirely, you’ll need to go beyond the basics to thoroughly define plagiarism, recognize it, and keep clear of it. Some examples of plagiarism that students find surprising include forgotten citations, poor paraphrasing, and re-submitting your own work in whole or in part for more than one assignment. This useful article provides more help in recognizing and understanding the different forms that academic dishonesty can take.

Of course, using your own words and ideas does not count as plagiarism, nor does using common knowledge . Basically, common knowledge is information that is well known by the average person. Examples of common knowledge:

• there are 12 months in a year
• the freezing point of Celsius is zero degrees
• Socrates was a Greek philosopher

So should you only include your original thoughts and common knowledge in your papers? Of course not! Research-based assignments are meant to demonstrate your skills as a researcher, after all, as well as your ability to build upon the work of others to formulate new ideas. To avoid accidentally committing an act that falls within the plagiarism definition when you’re using another person’s words or ideas, though, you need to give them proper credit. This means you’ll need to clearly identify direct quotations or properly paraphrase them when including them in your paper.

Regardless of your approach, you’ll also need to cite your sources according to the style your professor specifies. Generally, you will use MLA format for the arts and humanities and APA format for the sciences, but it’s always best to check with your instructor when you’re unsure.

If you know what style to use but still aren’t sure how to create your citations, don’t fret! Our library of resources includes free guides to help you learn about various styles so you can properly structure and place them. And our premium tools not only help you check grammar, spelling, and originality in your papers, but subscribers also enjoy access to our citation creation tools!

What are the Different Types of Plagiarism?

In addition to the question “what is plagiarism,” you may also be wondering, “why do students plagiarize?” While some students do intentionally plagiarize because they believe they can pass off someone else’s work as their own to avoid spending time on their assignments, many others do so accidentally. They may not understand how broad the plagiarism definition is or they haven’t learned how to research and cite their sources properly. That is why it is vital to recognize plagiarism in all of its forms if you wish to ensure the integrity of your work.

Examples of plagiarism & How to prevent it

Direct plagiarism:

Intentionally copying another person’s work without including a citation that gives credit to the source. When most students are asked to identify potential plagiarism examples and behaviors, this direct and deliberate act is what they think of first.

• Prevention: If you use an idea or quote from another source, cite it in the text. Make it clear that it was not your own words. 

Incremental plagiarism:

Copying parts of another person’s work, such as phrases, sentences, or paragraphs without crediting the source. When deciding which tools to use to check a paper for plagiarism , instructors often seek out those that will identify incremental forms as well as instances of direct copying and similar phrasing.

• Prevention : Decide to either directly quote the phrases or sentences you want to use, or write a good paraphrase. In both cases, be sure to add a citation. Using a plagiarism checker could also help you identify problematic passages.

Self-plagiarism:

Academic self-plagiarism occurs when a student submits the same paper or parts of a paper for more than one assignment. When your instructors are grading your papers, they’re assessing your research and writing skills in the present. When you submit work that you completed in the past, they are both unable to evaluate your current skills and unaware that you haven’t completed the assignment.

• Prevention: Write a new paper for each assignment you’re assigned. If you feel strongly that your past work could enhance your new paper, speak to your instructor and ask for permission first.

Misleading citations:

Including a citation for a quote or idea that misrepresents the source material. This can occur if a student does not understand the reference they are citing; if a student includes a citation for a disreputable source; or the source material simply does not align with the idea or argument that the student has attributed to it.

• Prevention: Carefully review your assignment to understand it. As you research, take the time to evaluate each source notes . Remember, it’s better to have quality citations over an abundance of citations.

Invented sources:

If a reference in a student’s bibliography is found not to exist, it is considered an invented source. This may occur if a student couldn’t find a reputable source to back their argument, or if they needed to include additional references to meet the requirements of the assignment and chose to take an unethical shortcut rather than completing the required amount of research. No matter the reason, this behavior ultimately hurts them in the long run. Not only will they fail to gain the experience they need to conduct research in the future properly, but they’ll also experience significant consequences if they’re caught.

• Prevention: Set aside time to do proper research so you can find enough sources. Start creating a list of sources as you’re researching and take good notes. This will help you keep track of your sources so none are forgotten. If you do end up forgetting where a quote came from, a paper checker could help you pinpoint the original source. 

Patchwriting/Spinning:

Patchwriting is often confused with paraphrasing, but there’s a significant difference. When you paraphrase, you demonstrate that you understand the topic well enough to restate it in your own words. When you patchwrite or spin, it is more akin to a word-swapping game; there’s no need to understand the subject, merely to have access to a thesaurus so you can substitute enough synonyms to mask the source material. This can be intentional, but it may also be a result of having a poor understanding of how to paraphrase.

• Prevention: Using your own words, write down the key points of the phrase or idea, and put them together in a sentence. Be sure to include a citation as well. 

A good way to test if you’re patchwriting or paraphrasing is to remove your sources from view. If you can write about what you’ve read without looking at the source material, you likely understand it well enough to paraphrase it. If you have to review the source material with each new sentence or consult a thesaurus while writing about it (except when you’re adding direct quotations), you may be spinning your sources instead of paraphrasing them.

Academic Integrity Policies and Statements

If you’re still uncertain about what counts as plagiarism, look for your school’s/ organization’s policies on academic integrity and plagiarism. The policies of academic institutions usually cover what is considered plagiarism, the consequences of committing it, and how to avoid it. One great example is Purdue University’s Academic Integrity statement .

What are the Consequences of Plagiarism?

No matter the setting, plagiarism is not taken lightly, and the consequences can be significant. For a good reason, too! Whether in an academic or professional setting, the plagiarism consequences reflect the seriousness of the act, which is ultimately a form of theft that hurts everyone involved.

Just as with the theft of a tangible object, there can be legal punishments for plagiarism. It is, after all, a form of copyright infringement in many instances. A quick search for plagiarism articles will reveal that professional instances of intellectual theft have resulted in civil lawsuits and can even be criminally prosecuted under rare circumstances. In addition to the possible legal consequences, professionals may lose their jobs or have to start over in a new field after their acts of fraud are uncovered.

As a student, you’re likely to wonder what happens if you plagiarize in college or high school. While there will almost always be consequences for this behavior, there is no one-size-fits-all plagiarism sentence. Depending on the circumstances, academic dishonesty could result in outcomes such as:

• You might get a zero for the assignment in which the infringement occurred.
• You may receive a failing grade for the class. If it is a required course, this could leave you without enough credits to move on to the next level until you can repeat it and, in some instances, postpone graduation.
• You may be expelled from your school or university.

The academic dishonesty may be noted on your transcript, which can lead to you not getting into your preferred college, graduate school, or Ph.D. program in the future.

Nobody wants to be known as a fraud or to have a reputation for dishonesty follow them through their career. And, given the consequences that can extend beyond just their reputation, it’s no wonder that professional and academic writers who wish to avoid them take the time to understand the complete definition of plagiarism and run their work through a plagiarism checker before sending it out into the world.

Even the vigilant can fall prey to inferior tools, unfortunately. Before selecting a plagiarism checker, you should understand how they work and what they can (and cannot) detect.

How We Check for Plagiarism

When exploring how to check for plagiarism, most students and professionals conclude that including a checking tool in their revision process is not only helpful but necessary. When you consider the Herculean task of checking each line of your paper against the text of each of your resources, the benefits of a checker are clear. Moreover, this manual approach would only alert you to matching text in the sources you’re aware of, after all, and leaves the sources you haven’t reviewed untouched.

But, hang on. Why would sources you haven’t reviewed factor into your review? The answer to this lies in the plagiarism definition you learned above. What is plagiarism? It’s presenting someone else’s work or ideas as your own, intentionally or otherwise. It is not uncommon to uncover an idea while you’re researching a topic and later misremember it as your own. This might even occur years after you originally came across it.

You might wonder: how can plagiarism be avoided if you have to account for the source of every thought you include in your work? A few exceptions minimize the scope of this. Common knowledge about your topic does not need to be supported by a citation, nor does knowledge that you gained through your personal experience. Using a subscription-based or free plagiarism checker will help you locate any passages that may fall into these categories so you can review them and decide for yourself whether a citation is needed.

EasyBib Plus writing tools provide easy, convenient, and reliable support to help you find potentially missed citations and can help you improve your paper into a high-quality paper with integrity. Simply upload your paper, select the checker, then sit back and relax as the site scans your document. In mere moments, we’ll search the web for passages of similar text and highlight duplicate content for your review.

Regardless of the tools you use to help you revise and polish your work, it’s ultimately your responsibility to ensure that you’re writing and submitting ethical work. That’s why our tools go beyond the basics and require your participation. The tool never automatically makes changes to your paper, but only flags sections that may need your attention and provides you with the matching source so you can to make an educated decision.

If you find that a citation is needed, our citation tools can help you create properly formatted citations and develop a complete bibliography. And, if you review the passage and determine that the match is coincidental, you can dismiss the alert and move on to the next.

Seamless Citation Creation

Professional writers and students alike can find creating citations incredibly confusing. Nevertheless, they are an integral part of a well-written and researched paper and a requirement in almost all academic settings. But, have you ever wondered why they are so important? Citations really do have a purpose—other than driving us crazy— that make it necessary always to cite our sources.

We cite our sources for a few important reasons:

We need to give credit where credit is due. When you use a quote from someone else’s work, you need to give credit for using their words and ideas. Research is often based on the works and ideas of others. However, to include the words and ideas of another without giving them proper credit is to plagiarize, even if the act was unintentional.

In addition, showing that you’ve done proper research by including in text & parenthetical citations and a comprehensive list of sources to back up your arguments gives your work a layer of credibility that can help you earn the trust of your reader or teacher.

Readers can find the sources you used.  When you’re writing high school or undergraduate papers, your only readers may be your instructors and peers. However, including citations at every level of writing helps to ensure that anyone who reads your work can access your sources to check their accuracy, learn more about your topic, and further their own research.

Sources can take your research and learning to the next level, too. When you are conducting research on a topic, checking the works cited or annotated bibliographies prepared by your sources can lead you down new avenues in your research to further develop your ideas and help you write your papers.

Correctly utilizing citations gives strength to your thoughts and opinions. Understanding the value of citations does not, unfortunately, make them any easier to create. We know how confusing it can be, but don’t throw in the towel on learning how to cite websites in MLA , create your APA citation website references, or format your works cited —this is where we come in!

While a free online plagiarism detector may tell you how much of your work is unoriginal and may even identify the passages that meet their plagiarize definition, a premium EasyBib Plus plagiarism checker account also gives you access to our powerful citation resources and generator so you can:

Scan your papers with the plagiarism tool to check for plagiarism-free work before you submit.

Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school.

Direct Plagiar ism:

Direct plagiarism is the deliberate act of copying another individual’s work or idea into an assignment without providing any type of acknowledgment. An example of this would be a student copying and pasting text from a source into their project, without using quotation marks or any kind of attribution.

Incremental Plagiarism : 

Copying bits and pieces from a single sentence and adding them into a project without attribution is a form of literary theft called incremental plagiarism . Just as with direct plagiarism, the incremental form attempts to disguise when a student or writer is taking credit for words and ideas that are not their own.

Patchwriting:

When a writer rephrases another author’s words (and it remains similar to the original words) and includes them without attribution in their work, it is known as patchwriting or mosaic writing .

How does it happen? Perhaps the writer rearranged words in the sentence, subbed out a few adjectives with synonyms, or used bits and pieces of the original wording and mixed it with their own. No matter the method, the original wording is often easy to spot as it peeks through its patchwork disguise.

Self-Plagiarism:

Plagiarizing another author’s words or ideas is an issue that most students recognize as wrong, but many are shocked to learn that reusing their own words can also fit the plagiarism definition. After all, they ask, how can I steal from myself?

Self-plagiarism is less about stealing and more about deceiving. When a student refurbishes or reuses work they completed in the past and turns it in a second time instead of completing new, original work, they are not honest with their teacher. Even reusing portions or paragraphs of your previous work without disclosing it is dishonest.

Do you have a paper you want to evaluate so you can confirm you’ve completed your research responsibly without plagiarizing (by accident)? A quick scan with the BibMe Plus plagiarism tool will help highlight phrases, sentences, or paragraphs in your paper that are found elsewhere on the internet. Each highlighted section has a prompt that will also ask you if you need a reference for it. Even better? If you review the source and determine that you need to add a citation, the plagiarism check tool will guide you through the steps of creating and inserting your reference. Pretty awesome, right? We think so too.

Lesser-Known Examples of Plagiarism

There are quite a few acts of intentional or unintentional dishonesty that students are surprised to learn also meet the definition of plagiarism.

Misleading Citations:

Including misleading citations is a form of academic dishonesty that is just as serious as direct infringement.

To understand how this fits into the plagiarize definition, consider the final result. If this type of plagiarism is undetected, the writer has deceived their audience and created a false belief about the words and ideas in the source material and its author. Whether it occurs intentionally or unintentionally, misleading citations draw a false link between an idea and a source and harm a student’s credibility.

Invented Sources:

While misleading references can occur as a result of not understanding your research, invented sources are more often the result of insufficient research or intentional deception. A student who can’t find a source to back up a point they want to make or who doesn’t want to commit the necessary time to ethically complete a paper might resort to including one or more invented sources in their bibliography. Whatever the cause, an invented source creates an illusion of credibility by tying an idea to a source that doesn’t exist.

An invented source can also be the result of poor note-taking. Perhaps you found the perfect quote to include in your introduction but forgot to write down the source. You know it’s wrong to plagiarize, but unless you invent a source you’ll have to remove the quote, right?

Wrong! Rather than choosing between removing the quote or inventing a reference, let the BibMe Plus plagiarism tool free up some time by helping you find the source and create an accurate citation. It’s quick and easy to scan your paper for plagiarism and, most importantly, it’s the ethical thing to do.

What Is Not Plagiarism

With the definition of plagiarism covering so much ground, it’s easy to raise the alarms and wonder if even the most innocent of acts might be construed as plagiarizing. Our advice? Don’t panic. Instead, sit back, relax, and check out these times when you can write your heart out, worry-free:

Common Knowledge:

Information that is widely known and accepted as fact is considered common knowledge. This can either be information that is known to most people in the world, in your country, in your state, or even just in your field of study, depending on the audience for your work. For example:

J.K. Rowling wrote the Harry Potter series.

This is a fact that is known widely enough that it is considered common knowledge and does not require a citation.

If your statement is considered common knowledge, you can include it in your paper without creating a citation. Keep in mind, though, that research papers showcase new ideas and analysis. Common knowledge is acceptable to include, but make sure you mix in information from outside sources as well.

Attributed Quote or Idea:

To include the ideas of others in your papers, you need only to attribute them to the original author to ensure you safely stay on the side of academic integrity. A proper paraphrase or direct quote with a citation is an excellent way to promote a point in your paper, while also demonstrating that you fully understand the author’s idea and have completed your research responsibly.

While most writers remember to add references for direct quotes, they can sometimes forget to include references when adding paraphrases into papers. A free plagiarism site may only help these writers pinpoint passages, but the BibMe Plus tool also helps you develop accurate references, in Chicago citation style and many others, in all types of situations. Quotes, paraphrases, full references: you name it, our plagiarism checker does it, and does it well.

Now that we’ve learned what is and isn’t plagiarism, let’s look at how to avoid it entirely.

How to Avoid Plagiarism

When you first learn to define plagiarism and realize how expansive the definition is, it can be intimidating to think about all the information you have to cite. That’s where the BibMe Plus online plagiarism tool comes in by helping to spot intentional and accidental plagiarism and flagging any matching text for your review.

When you use the plagiarism tool, or any of our resources, your paper always stays in your control. You’ll be given the potential source for each flagged passage so you can review it and decide whether to create a citation or dismiss the alert.

If you find that you need to add a citation, we’ve got your back. There are BibMe citing tools that can help guide you through the process of creating and styling a citation for your paper.

No matter what tools you use to help complete your work ethically, whether they’re free plagiarism tools or not, you are ultimately responsible for the work that you turn in. Remember, the best time to find errors or unintentional infringement is BEFORE you turn in your paper, not after. When in doubt, run a BibMe Plus plagiarism check to help you find any passages that you may have missed on your own, and use the free tools to create and insert your citations in more styles than even imaginable.

Unintentionally plagiarizing isn’t the only thing to worry about when writing and revising a paper—you also don’t want to lose points for small grammatical mistakes. Luckily, the BibMe Plus grammar checker and plagiarism tool will complete a spell check and review your document for style, punctuation, sentence structure, verb tense, pronoun -antecedent agreement, and more!

Plagiarism is the act of copying someone's work or ideas and claiming them as your own. It can even be copying your own written ideas. Essay plagiarism can be as simple as copying a paragraph from another source without citation, but it can also be as severe as copying entire pages from another written source, such as an essay, book, post, or article. To check for plagiarism, you need to know the common mistakes of plagiarists, as well as ways to confirm your suspicions.

Looking for Warning Signs in the Style and Grammar

• For instance, does this person usually make typos, but all of a sudden provides a perfectly clean essay? Does this person usually have incoherent or poorly formed concepts, then suddenly presents well-formulated statements?
• Pull out the student’s portfolio of work from your class as a point of comparison. If you are suspicious, it maybe helpful to request copies of the student’s work from fellow teachers, too.

• You may also note that points of view shift or that the student abruptly ends thoughts by switching to another topic.
• Also, look for a weak start and end with an amazing middle, or some other mix of weak and strong areas. While this mixture can be a sign of a student struggling to shape an essay logically, it can also be a sign of plagiarism if a student has cut and pasted from various sources.

• However, inconsistent spelling can also be the work of a poor writer.

• For example, if you are teaching intro composition and the student is doing graduate-level work, you might want to check their essay more closely.

• For instance, you may find that when discussing a book like Frankenstein, a particular phrase such as "represents the monster within each of us," shows up across many papers.

Checking for Other Signs of Plagiarism

• Also, check if the citation even exists. In some cases, students make up the citations altogether, or claim that a chapter essay in a book exists when it doesn't. Perhaps you have access to the book in question and can check. Check Google Books, or look online for article citations.

• Also check for old resources, which may indicate the paper is older.

Confirming Plagiarism

• If the text has been copied either verbatim or fairly closely, it's likely that the search engine will return some exact matches. Any online source that has the same text should appear on the first page of results.

• Turnitin is one widely used site for plagiarism checking. You can also try Plagiarisma or Copyleaks.

• If you're not 100 percent sure the student plagiarized, you can also use the meeting to determine if the student actually knows the material or not. [8] X Research source However, some introverted students may freeze up under these circumstances, whether they wrote the material or not, which makes it tricky sometimes to detect plagiarism.
• Usually, if the student actually wrote the paper, they will know what they are talking about and will be able to talk about it thoroughly with you. And generally, if they didn’t write it themselves, they will not be able to do this.

• For younger students, contact the student’s parents and follow up with any relevant administrators who need to be aware of the incident. Talking to older students directly is acceptable, and there will typically be repercussions at the school’s honor council.

Expert Q&A

• Show students how to avoid plagiarism. Don't just scare them off, as for some students, scare tactics can often result in defiance or a need to get one over on you. Give them the tools and pathways to write and research better. Thanks Helpful 0 Not Helpful 0
• It will be harder to spot a person who pays someone to write an original essay or do an exam for them. Check to see whether your institution has checks in place to ensure that the right person turns up to sit exams and use your expectations of the student or class level to guide your own instincts about the work you're reading.

What Is Plagiarism? | Definition & Examples

Plagiarism means using someone else’s work without giving them proper credit. In academic writing, plagiarizing involves using words, ideas, or information from a source without citing it correctly. In practice, this can mean a few different things.

Table of contents

Common questions about plagiarism, more tools and resources for avoiding plagiarism, frequently asked questions about plagiarism.

It’s easy to understand why you shouldn’t buy essays, but students often struggle with the details of quoting , paraphrasing , and citing sources . Below, we address some questions and misconceptions students often have about plagiarism.

I need to quote and paraphrase a lot. Won’t my paper be full of distracting citations?

It’s true that some papers do feature a lot of citations. There are ways to reduce clutter by citing more efficiently, such as:

• Combining multiple citations into one set of parentheses (usually separated by semicolons )
• Not repeating the full citation when you cite the same source multiple times in a row
• Using “ ibid. ” to indicate a repeated citation (in certain styles)
• Omitting citations for information that is common knowledge

Do I need to cite a certain number of sources? Can citing too much be a bad thing?

There’s no fixed number of sources you should cite. Your use of sources should be based on strengthening your argument, not meeting a quota. A high number of citations isn’t inherently a good or bad thing. Some types of academic text (e.g., a literature review ) are more likely to cite a lot of sources than others.

When you do think you’ve cited too much, it’s worth considering whether you need all the information you’ve included. All information should directly contribute to your argument, not just be tangentially related.

One thing you should avoid is quoting too much. If large portions of your text consist of someone else’s words, it distracts from your own arguments. It’s usually better to paraphrase unless you’re specifically analyzing the language of the source (e.g., in literary analysis ).

Is it better to just avoid using sources so I don’t risk accidental plagiarism?

No, using sources is an essential part of academic writing . Academic research is an ongoing conversation between researchers. Drawing on other sources, and positioning your own ideas in relation to them, is not optional.

But it’s understandable to be concerned about plagiarism. If you’re worried about the possibility of accidental plagiarism, make sure to:

• Quote and paraphrase sources correctly
• Manage and cite your sources using a citation generator
• Use a plagiarism checker before submitting your work to detect any problems
• Use generative AI tools responsibly (outputs may be detected by an AI detector )

Is paraphrasing a kind of plagiarism?

No, paraphrasing is just a way of incorporating information from a source into your text by putting it into your own words. As long as you cite the source correctly, paraphrasing is the best way to incorporate information in most cases.

However, paraphrasing can be considered plagiarism if you:

• Don’t cite the source of the information, or cite it incorrectly
• Phrase the information in a way that’s too close to the original (e.g., just swapping out a couple of words instead of reformulating the sentence)

Scribbr offers a variety of tools and services designed to help you with citations and plagiarism checking, including the best plagiarism checker available.

The consequences of plagiarism vary depending on the type of plagiarism and the context in which it occurs. For example, submitting a whole paper by someone else will have the most severe consequences, while accidental citation errors are considered less serious.

If you’re a student, then you might fail the course, be suspended or expelled, or be obligated to attend a workshop on plagiarism. It depends on whether it’s your first offense or you’ve done it before.

As an academic or professional, plagiarizing seriously damages your reputation. You might also lose your research funding or your job, and you could even face legal consequences for copyright infringement.

Paraphrasing without crediting the original author is a form of plagiarism , because you’re presenting someone else’s ideas as if they were your own.

However, paraphrasing is not plagiarism if you correctly cite the source . This means including an in-text citation and a full reference, formatted according to your required citation style .

As well as citing, make sure that any paraphrased text is completely rewritten in your own words.

Accidental plagiarism is one of the most common examples of plagiarism . Perhaps you forgot to cite a source, or paraphrased something a bit too closely. Maybe you can’t remember where you got an idea from, and aren’t totally sure if it’s original or not.

These all count as plagiarism, even though you didn’t do it on purpose. When in doubt, make sure you’re citing your sources . Also consider running your work through a plagiarism checker tool prior to submission, which work by using advanced database software to scan for matches between your text and existing texts.

Scribbr’s Plagiarism Checker takes less than 10 minutes and can help you turn in your paper with confidence.

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).
