How It Works
Paste original text on the left and modified text on the right to inspect differences in real time.
- Diff Modes: Compare line-by-line, word-by-word, or character-by-character.
- Side-by-Side & Unified: Switch between dual-column comparison and unified inline diff views.
- Privacy First: Comparison runs 100% locally in your browser without transmitting your data.
