Plagiarism scanner: check your writing for originality

Our tool will help you avoid plagiarism, including poor paraphrasing, missing in-text citations, and accidental matches. When you upload your text, our tool compares it against a wide range of sources across different open-access databases.

You receive a thorough report with a similarity percentage, highlighted unoriginal passages, and links to relevant sources. You can then review any flagged content, fix issues, and run one more check to make sure everything is resolved.

One thing our customers appreciate most is how easy the tool is to use. You don’t need to sign up, and there are no limits on free checks. If you’re looking for the best plagiarism checker, ours is definitely worth trying.

Blatant copying of someone else’s writing isn’t the only form of plagiarism, which is why it’s always important to use a checker to detect plagiarism in your work, even if you’re fairly sure that it’s original. Less obvious types of plagiarism include accidental, mosaic, patchwork, bibliographic, and self-plagiarism. Even just poor paraphrasing or misattribution in citations can lead to unintentional plagiarism.

Absolutely. Students are not only allowed but actually encouraged to double-check the originality of their work using a reliable free plagiarism checker. It can help you catch missed or incorrectly credited unoriginal content, including accidental plagiarism. However, keep in mind that no matter what tool you use, the results aren’t always the same as those from Turnitin.

Yes, even the most reliable plagiarism detector can miss something or produce false positives. Plus, unless you’re only quoting from open sources, the tool you’re using might lack access to certain databases and won’t be able to compare all relevant material. Our detector has consistently high accuracy and is sensitive enough to catch unoriginal content even when paraphrased. Nonetheless, we always recommend critically reviewing your report and double-checking your work.

To avoid getting in trouble for plagiarizing, always credit your sources correctly and don’t neglect to check for plagiarism. Even if you thoroughly paraphrase someone else’s ideas, you still need to cite the original source. Also, no matter how confident you are that you haven’t plagiarized anything, it’s worth checking. Everyone can make mistakes, miss a citation, or accidentally copy something and forget about it. Unintentional plagiarism still counts.

No, when you use our detector to scan for plagiarism, we don’t store or retain your work. You can easily check this by refreshing the page: once you refresh, your work disappears, which confirms that nothing is saved on our servers. As we don’t store or share your text, using our tool won’t cause your writing to be flagged in future plagiarism checks.

Not really. Of course, you can check every citation manually to make sure you’ve cited the right sources. You can also ensure the correct formatting of all direct quotes. But you can’t spot paraphrased content with the naked eye, nor can you catch a missed citation if you forgot to add one. Without a free plagiarism checker online, you’re risking being accused of plagiarism, intentional or not.

No, when you run your writing through our plagiarism scanner, you get a detailed report that contains much more than just a similarity percentage. All unoriginal content will be highlighted for convenient review. Also, you’ll get source matches for all highlighted passages, which is convenient if you need to credit the original but don’t remember where exactly the information is coming from.

A plagiarism detector and an AI detector are both helpful tools that any writer should use, but they serve different purposes. When you check your text for AI, you verify that it doesn’t contain passages that read like AI-generated writing. In turn, a plagiarism identifier helps you spot unoriginal content in your work, along with its matching sources.

How to properly cite your sources depends on what you’re writing. If it’s an academic assignment, in-text citations and a list of references at the end of your work are typically required. Make sure to use the right citation style: MLA, APA, Chicago, or whatever your instructions call for. If it’s an article for an online publication or a blog post, embedded links to the original sources are usually enough.

Unless you’re writing creative fiction, such as a short story, your work can almost never be completely plagiarism-free. It may contain direct quotes, topic-specific terminology, paraphrased ideas from other sources, and other unoriginal content. However, as long as everything is properly cited, you won’t get in trouble. Typically, a similarity score of 5–15% is considered acceptable, depending on what you’re writing.

No, using our checker won’t cause originality issues with your work. We don’t steal your writing or add it to any external databases that could make it appear unoriginal. If your work was highly original to begin with, that won’t change after you run it through our checker. At the same time, if it contained a lot of plagiarized content, it will remain unoriginal.

Using high-sensitivity plagiarism detection software, our tool compares your work against a large database of open-source academic and general content to spot similarities. The report includes links to matched sources so you can review and double-check them if needed. Unfortunately, only Turnitin has access to most schools’ internal databases of student papers, so no other detector is able to compare your writing against those.

Unless you reuse the papers you’ve submitted before or paraphrase your peers’ work, the report from our free plagiarism checker for students will most likely match your school’s results. Colleges typically use Turnitin or similar software with access to internal student-paper databases. Those databases aren’t accessible to commercial tools, not even the best ones. That’s why we always recommend students be extra-cautious about self-plagiarism — you might not be able to check for it.

Yes, you can safely use our detector without worrying that your text might end up in some database and get you in trouble later on. We don’t store your content or share your content. Plus, unlike most plagiarism detectors, ours doesn’t require registration. You have access to all of its features with no sign-up, so you don’t even have to share any identifying information.
