Text Diff

Paste two versions of any text or code and see exactly which lines were added, removed or kept.

🔒 Runs entirely on your device. Nothing you paste or pick is uploaded.

How to compare two texts

Paste the original on the left and the new version on the right, then press Compare. Removed lines are shown in red with a −, added lines in green with a +. Use it for code, contracts, essays, config files or translations.

How does the diff work?

It finds the longest common subsequence of lines — the same idea behind git diff — so moved or edited lines show up as a removal plus an addition. Comparison happens entirely on your device.
