How it works
- Both texts are split into lines and compared with a longest common subsequence (LCS) algorithm.
- Green rows are lines added in the new version, red rows are lines removed from the old version.
- Unchanged lines stay white, so you can scan exactly what changed and where.
- Your text never leaves your browser — the diff is computed locally with JavaScript.
