Text Diff
Paste an original and a modified text to see exactly what changed: removed lines are marked red, added lines green. Great for reviewing edits, code and drafts.
FAQ
How are differences calculated?
With the classic longest-common-subsequence algorithm on lines — the same principle behind Git diffs.
Is there a size limit?
Each side can hold up to 2,000 lines, which covers most documents and code files comfortably.
Is my text sent to a server?
No — the comparison runs entirely in your browser.
