About Online Diff Checker
Our free online Diff Checker compares two texts (Original vs Modified) and highlights additions in green and deletions in red. It uses the dynamic programming Longest Common Subsequence (LCS) algorithm to align lines side-by-side or in unified Git patch formatting entirely client-side.
How to use Online Diff Checker
- Paste your original document into the 'Original Text (A)' panel.
- Paste your edited document into the 'Modified Text (B)' panel.
- Choose between 'Split View' (aligned double-column) or 'Unified View' (Git patch styling) to analyze changes.
