DocomintText Diff Checker
Compare two blocks of text and see exactly what was added or removed.
Highlights the actual words that changed between two versions of a paragraph, a contract clause, or a config file — word-level, not line-level, so a single-word edit inside a long sentence is easy to spot instead of the whole line just being flagged as "changed."
Example: Comparing "The quick brown fox jumps" against "The quick red fox leaps" highlights "brown" and "jumps" as removed and "red" and "leaps" as added, while the unchanged words stay plain.
How it works
- Paste the original text on the left
- Paste the changed text on the right
- Additions and deletions are highlighted instantly, on your device
Frequently asked questions
Is the comparison word-level or character-level?
Word-level — added and removed words or phrases are highlighted, which is easier to read than a character-by-character diff for prose.
Is my text uploaded anywhere?
No — Text Diff Checker runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
If I just move a sentence to a different place, does that show as a change?
Yes — this compares word-by-word in sequence, so moving a whole sentence elsewhere shows as a removal in its old spot and an addition in its new one, not as \"moved.\"
