Paste two texts — the difference is computed live. Switch between line, word and character modes; copy the result as a git-style unified diff.
Lines compares whole lines — the usual view for source code and config files. Words and Chars compare within a line, useful for spotting a small edit inside a long paragraph or sentence.
"Copy unified diff" produces a standard git-style patch (---/+++/@@ headers), regardless of which mode is selected for the on-screen view.
The comparison runs entirely in your browser. Neither text is uploaded.
