Searches the web for your text (Google Programmable Search) and checks sentence-level overlap against what it finds
A plagiarism checker compares your text against other writing to flag sentences that closely match something already published elsewhere. This one works by searching the live web for your text and comparing sentence by sentence — no account needed, results appear right on this page.
Paste your text into the box above.
Press "Check Plagiarism (search the web)."
Review the similarity score and any matched sentences, with links to their source.
Yes — there's no paywall, no watermark, and no sign-up required. Paste your text and press Check Plagiarism.
It takes your longest sentences and searches for them on the live web, then fetches a handful of the pages that come back and pulls out their text. Each of your sentences is then compared against every sentence on those pages, and anything similar enough gets flagged as a match with a link to where it was found.
The score is the percentage of your sentences that closely matched something found on the web — not a judgment of your document's overall originality. A high score on a few sentences might just mean you used a common phrase; check the actual matches, not just the number.
Each match shows your sentence side by side with the source sentence it resembles, a similarity percentage, and a link to where it was found — so you can judge for yourself whether it's a real overlap worth addressing or just shared common wording.
No. Turnitin checks against a licensed database of academic papers and a private archive of previously submitted student work, which this tool has no access to. Use this as a quick self-check before submitting something, not as a guarantee that a formal originality check will come back clean.
Students use it to catch accidental unattributed overlap before turning in an assignment. Writers and bloggers use it to make sure a paraphrase or summary drifted far enough from its source.
Catch accidental overlap with a source you read while researching.
Confirm your own rewrite of someone else's idea is different enough in wording.
Spot-check a blog post or article before it goes live.
Yes — your text is processed for the request only and never saved anywhere. No account or sign-up is required. Note that checking it does send parts of your text out as public web searches, so avoid pasting anything genuinely confidential.
Yes — there's no paywall, no watermark, and no sign-up required. Paste your text and press Check Plagiarism.
No. Turnitin checks against a private database of previously submitted student papers and licensed academic content. This tool only searches the live, publicly indexed web, so it won't catch overlap with unpublished or paywalled sources.
It searches the live web using your longest sentences as search queries, fetches a handful of the pages it finds, and compares your sentences against the text on those pages.
It's the percentage of your sentences that closely match a sentence found on a source page — not a measure of your whole document's originality in a legal or academic sense.
Yes. It only searches a handful of your longest sentences and checks a limited number of source pages, so shorter overlapping passages or sources outside the top web search results can be missed.
No. Your text is processed for the request and never saved anywhere.
