Text Diff
Paste two versions, see what changed — added lines green, removed lines red. Everything stays on your device.
Paste both texts to compare.
Is my text uploaded?
No. The comparison runs entirely in your browser — safe for contracts, code and private notes.
How does the comparison work?
A longest-common-subsequence algorithm aligns the two texts line by line, so a single inserted paragraph doesn't mark everything below it as changed.
Can I compare code?
Yes — the diff is whitespace-exact and monospaced, so indentation changes are visible too.
