Text Diff
Compare two texts line by line and see exactly what changed.
About this tool
Compare two texts online and see additions and deletions line by line, color-coded. Useful for reviewing edits to contracts, articles or configuration files without installing anything. The comparison runs on your device - neither version is uploaded.
How does the comparison work?
The tool computes a longest-common-subsequence diff per line, the same family of algorithm used by version-control tools.
Is there a size limit?
Extremely large texts are declined to keep your browser responsive; everyday documents work fine.
