Text Compare / Diff

Paste two texts and instantly see what changed — additions, deletions, and unchanged content highlighted clearly.

This text compare tool highlights exactly what changed between two pieces of text. Paste your original version on the left and the edited version on the right, choose whether to compare by words, lines, or individual characters, and click Compare to see additions, deletions, and unchanged sections marked in color. A summary bar totals how many words or lines were added, removed, or left the same, so you can gauge the scope of the edit at a glance. The Swap button lets you flip the two texts if you loaded them backwards, and everything runs locally in your browser without uploading either document anywhere. It's useful for writers comparing draft revisions, developers reviewing code or config changes, and editors checking what a collaborator altered in a document.

Diff Mode:
Original
Modified
