Text & Code Diff Checker

Compare text, code, or JSON. Side-by-side or inline, with word/char precision, ignore options, hide unchanged lines, syntax highlighting, and JSON tree comparison. 100% private — nothing leaves your browser.

Original text 1 line

Changed text 1 line

Precision:

Paste or upload two texts to compare

Additions in green, deletions in red — with word-level highlighting inside modified lines.

🔒 100% private — your text never leaves your device. Comparison, reports, and patches are all generated locally.
