Free plagiarism checker
Find out whether your articles, product descriptions or course material have been copied, and see exactly which sentences match.
How the checker works
- We split your text into sentences and pick the most distinctive ones.
- Check the web: each is searched as an exact phrase, so only pages containing those words come back.
- We load the likely matches and compare them with your text sentence by sentence, using overlapping five-word sequences, so lightly reworded copying is still caught.
- You get a score, the sources and your text with every matching sentence highlighted.
What the score means
| Score | What it usually means |
|---|---|
| 0–9% | Mostly original. Short common phrases and quotes can cause small matches. |
| 10–39% | Some passages match. Check whether they are quotes, your own earlier work, or copying. |
| 40% and above | Large parts match a source. If the source copied you, that is a strong takedown case. |
Found your text on another site?
Copying your writing word for word is copyright infringement. Save a screenshot of the page with its address and date, then send a takedown with our DMCA notice generator (USA), UK notice or EU and Netherlands notice. If the site ignores you, find its host with the host finder and ask Google to delist the page.
Common questions
Is this plagiarism checker free?
Yes. Comparing with a web page or a second text is unlimited within the hourly limit. Web-wide checks are free up to 1,500 words per check.
Do you save my text?
No. Your text is processed for the check and not stored or shared.
Can it detect paraphrasing?
It catches copying with small edits, such as changed words or reordered phrases within a sentence. Heavily rewritten text may not be detected.
Does it check academic databases?
No. It checks publicly available web pages, which is where copied website and marketing content appears.
What should I do if someone copied my article?
Screenshot the page, then send a takedown notice to the site or its host. Our free generators cover the USA, UK, Canada and the EU, or you can send the links to us.
