What the Plagiarism Checker does
The plagiarism checker scans your text for internal duplication and repeated phrasing, flagging sentences that appear more than once so you can rewrite them.
How it works
The tool splits your content into sentences, normalises them, and looks for exact or near-exact repeats. It also highlights long phrases that recur, which are the usual signs of copy-paste overlap.
It is a fast first pass that catches accidental duplication in your own drafts. For a full comparison against the whole web, pair it with a dedicated external service.
