FAQ

Questions, answered.

How does this plagiarism check work?

It splits your text into sentences, flags passages that are repeated inside the document, and builds an exact-phrase search link for each distinctive sentence. Opening a link shows instantly whether that sentence already exists on another website.

Why doesn’t it give a single “% plagiarised” score?

A percentage is only honest if the text is compared with billions of web pages, which needs a paid index. Rather than invent a number, this tool shows you exactly which sentences to verify and lets you check them against Google or Bing in one click.

Is my text uploaded?

No. The analysis runs in your browser. A sentence is only sent to a search engine if you choose to open its search link.
