What this plagiarism checker does
This plagiarism checker splits your text into short passages and searches the web for an exact match on each one. Any passage that turns up a matching page is flagged and linked straight to its source, so you see exactly what to rewrite or cite — not just a single unexplained percentage score.
It's built for a quick, practical check before you publish or submit something: pasting in an essay, a blog draft, or a product description and seeing precisely which sentences already exist somewhere else on the web.
How to check text for plagiarism
- Get your text into the box: paste it directly, upload a .txt, .docx or .pdf file, or paste a webpage URL and pull its text automatically.
- Select Check for plagiarism.
- Review the results: each flagged passage links to the matching source page, so you can see the actual overlap and decide whether to rewrite it or cite it.
Uploaded files are read entirely in your browser — a .txt, .docx or .pdf never leaves your device just to extract its text. A webpage URL is different: pulling its text requires fetching that page through the server, since a browser can't read another site's page directly.
Why it's a free check with a daily limit
Each check uses a limited pool of search queries behind the scenes — this is a "Pro" tool because there's a real cost to running it, unlike a purely client-side tool. The daily limit on free checks keeps the tool available to everyone rather than a few heavy users exhausting the shared quota; see the usage banner on the tool for your current limit.
What gets skipped, and why
Very short or extremely generic passages are intentionally skipped rather than searched, since they'd just produce false matches against unrelated pages that happen to share a common phrase. A flagged passage means a genuine, specific match was found — not a coincidental overlap in common wording.
