Plagiarism Checker: what it's good for
Before you hand in an essay, pay a freelancer or publish a guest post, it's worth knowing whether the text already exists somewhere online. Paste it or upload the document: the checker picks its most distinctive passages, runs each one as an exact-phrase web search, and lists every page it found with a link you can open. You see the matches for yourself instead of trusting a mystery percentage. Free to try, no sign-up.

There's nothing to download and no account to open. Type or paste your request into the box at the top of this page, and Plagiarism Checker gets back to you within seconds — at any hour, at no cost.
Everyday ways to put Plagiarism Checker to work
- Run a last check on your essay or thesis before the deadline
- Make sure an article you paid a freelancer for is original
- Find out whether a site has copied your blog post or product page
- Check a press release or newsletter before it goes out
- Gather the actual source links before raising a plagiarism concern
Quick answers
- Is the web search real, or just an estimate?
- Real. Distinctive passages from your text are searched word for word, and every source listed is an existing page you can click through to and compare.
- How many checks can I run for free?
- You get 1 check a day with no account; Premium raises that allowance a long way. The daily allowance is lower than for the other tools because every check launches several live web searches.
- Will it tell me if a text was written by AI?
- No — that's a separate question, answered by the AI detector. Plagiarism checking looks for copies online; AI detection looks at writing style. Running both gives you the fuller picture.
- What do I see in the results?
- The share of checked passages that turned up online, those passages highlighted in your text, and a list of sources marked as identical or very close, each with a link to the page.
