About This Text Diff Tool
This tool uses the LCS (Longest Common Subsequence) algorithm to compare two texts line by line. All processing happens in your browser -- nothing is uploaded.
- Code Review: Compare different versions of source code to spot changes quickly
- Document Tracking: Track changes between document revisions to ensure nothing is missed
- Content Editing: Compare drafts to see exactly what was added, removed, or modified
- Configuration Files: Diff server configs or settings files across environments
Differences are color-coded: green for added lines, red for removed lines, and yellow for modified lines.
