See exactly what changed between two versions
Paste the original text on the left and the edited version on the right, then hit Compare. Changed lines are highlighted git-style: red for removals, green for additions, with untouched lines dimmed for context.
It works for anything line-based — contracts, essays, configuration files, code, or two exports you suspect aren't identical.
Frequently asked questions
Is my text sent to a server?
No. The comparison runs in your browser. People diff contracts, code, and confidential drafts — none of it should sit on someone else's server, and here it doesn't.
How does the comparison work?
It uses a longest-common-subsequence algorithm on lines — the same approach as git diff. Removed lines show in red with a −, added lines in green with a +.
Is there a size limit?
Each side is capped at 5,000 lines to keep the comparison instant. That covers almost any document or source file.
