How it works
The tool supports pasted text, file uploads, and URL checks, and it includes a grammar checker and citation generator as extras. It is aimed at students checking assignments and writers verifying originality before publication.
As a free tool it is convenient, but it is not a substitute for the institutional detectors universities use, which search subscription databases the free tools cannot reach. Use it as a first-pass check, not a final verdict.
