Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

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.

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.

That's why finding out an exact percentage of non-unique text in their paper is the number one priority for many students. And our professional online plagiarism checker can help you with that.

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. Failing to acknowledge the author's work or presenting it as one's own is considered plagiarism. 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.

In addition to the ethical considerations, there are legal consequences for plagiarism. In some cases, it may even lead to litigation. Therefore, it is essential to be mindful of plagiarism and avoid it at all costs.

To avoid unintentional plagiarism, one should learn how to properly cite and reference sources, paraphrase effectively, and avoid copying and pasting. It is also important to use plagiarism checker tools to ensure the originality and uniqueness of one's work.

In summary, plagiarism is a serious offense that can have far-reaching consequences. It is crucial to understand its implications, adhere to academic integrity principles, and always check your work for plagiarism to avoid any negative consequences.

To further ensure your academic integrity, familiarizing yourself with different ways to avoid plagiarism can significantly enhance the originality of your work.
