What DiffChecker does
Paste the original text on the left, the modified text on the right, and click Compare.
- Side-by-side line-by-line summary: removed, modified, and added lines.
- Word-level highlighting — only the actually changed spans are marked in modified lines, not the whole line.
- Export the modified version as .txt or copy it with Copy modified.
- Free during the pilot, no sign-up needed.
