  3. Enable inline highlight to see word-level changes inside changed lines.
  4. Copy the diff or download JSON for sharing or debugging.

FAQ & privacy

Does this run locally? Yes. Everything runs in your browser; text is not uploaded.

Large files? Inputs over ~200k characters or 10k lines will show a warning; consider trimming first.

Whitespace differences? Use the whitespace controls above to dampen spacing-only changes.
