Free · No word limit

Free plagiarism checker

Check whether your text has been copied – or copies someone else. Search the web for its most distinctive sentences in one click, and compare it word for word with any page.

How does this plagiarism checker work?

  1. We pick your most distinctive sentences – the ones with the most unusual wording, which are the most likely to be unique.
  2. You search for each one, word for word, on Google or Bing with one click. If another page shows up with the same wording, the text has been copied one way or the other.
  3. Compare with any page. Add the address of a page you suspect and we measure what share of your text appears on it word for word, and show the matching passages.

Your text is never stored, and the sentence picking happens in your browser. Unlike many free checkers, there's no word limit and no sign-up.

Does duplicate content hurt SEO?

Google doesn't penalise ordinary duplication, but when several pages have the same text it usually shows only one of them – and it may not be yours. Copying content wholesale from other sites can count as scraped content under Google's spam policies. Make sure your important pages say something in your own words.

What should I do if someone has copied my content?

Contact the site owner first and ask them to remove it or credit you. If that doesn't work, you can file a copyright removal request with Google under the Digital Millennium Copyright Act (DMCA) form, and contact the site's web host.

Frequently asked questions

Is this as thorough as paid plagiarism checkers?

Paid checkers compare against their own databases of web pages and academic papers. Ours uses Google and Bing's own indexes, one sentence at a time, which is excellent for spotting web copies but doesn't cover private academic databases.

Is my text kept?

No. Picking sentences happens in your browser, and when you compare with a page we only fetch that page.
