About this tool
Compare two versions of an article, code or contract to see what changed. Removed lines show in red and added lines in green.
It uses the longest common subsequence algorithm on lines, and processing happens locally.
Frequently asked questions
Is the comparison character-level?
No, it is line-level; a line with one changed letter counts as removed and added.
Is there a size limit?
Extremely large comparisons are refused to keep your browser responsive.
