Good to know
Plagiarism Checker Free compares your text against a pasted source using phrase matching, and the ignore-common-words mode drops frequent stop words like the, and and of before matching so overlap reflects content rather than grammar. It is free and local, with no web search and no account, so it cannot find matches that are not in the source you provide. Each box is compared up to the first 60,000 characters with a note.
Frequently asked questions
How does ignoring common words change the result?
It removes frequent stop words before matching, so shared everyday words no longer count and the score reflects meaningful overlap.
Is it really free and without sign-up?
Yes. It runs in your browser with no account and no payment, and your text is never uploaded.
Can it find matches anywhere on the web?
No. With no web search it can only compare against the source you paste, so it will miss anything you do not provide.
Why might the score be lower than other checkers?
Dropping common words and comparing only a pasted source usually yields a tighter, lower match than web-scale tools.
