Diff
Compare text online
Paste two versions of any text and instantly see a line-by-line diff — additions in green, deletions in red, unchanged lines in grey. No upload, no sign-up, no server required.
Useful for comparing code snippets, config files, contract drafts, or any text where the differences matter.
FAQ
Is my text sent anywhere? No — the diff algorithm runs entirely in your browser.
