Text diff (compare texts)
See line by line what changed between two versions of a text.
Paste two versions of a text, contract, code or list and see the differences highlighted: added lines in green, removed lines in amber. The algorithm (the same principle as git diff) runs in your browser — compare confidential documents without sending them anywhere.
Compare two versions of a text
Text comparison (diff) shows, side by side, what changed between two versions: added, removed and altered lines are highlighted. It is what you use to review a contract revision, see what changed between two drafts, or compare answers, lists or code snippets without reading everything again word by word.
How to read the result
Green lines exist only in the new version (added); red lines exist only in the old one (removed); altered passages appear on both sides. This format matches what version-control tools use, so a glance tells you instantly what the editor, reviewer or other party changed.
Runs in the browser, texts stay private
The comparison happens on your device — both texts stay in the browser, which is essential for confidential documents like contracts and proposals. Paste the two versions and compare as many times as you like, with no limit and no sign-up.
Frequently asked questions
Is the comparison per line or per word?
Per line, like git diff: each line is compared whole. If you change one word inside a line, it shows as one removed line plus one added line — the clearest format for reviewing changes.
Is it good for comparing code and contracts?
Yes, that is the ideal use: clause versions, name lists, config files, SQL. Since processing is local, pasting confidential material is not a problem.
Is there a size limit?
Up to 2,000 lines per side, enough for large documents and code files. The limit exists so the comparison stays instant and memory-light even on phones.
