How It Works: Client-Side Processing
Your privacy is our priority. Here's why our approach is different:
Diff Algorithm
Uses an efficient diff algorithm to compute the minimum set of changes between two texts.
Side-by-Side View
Clear visual presentation shows original and modified text with changes highlighted inline.
Line Highlighting
Color-coded additions (green) and deletions (red) make it easy to spot exactly what changed.
Frequently Asked Questions
Is my text sent to any server?
No, all text comparison happens entirely in your browser. Your documents never leave your device - safe for comparing sensitive code, contracts, or confidential documents.
What's the difference between diff modes?
Character mode shows every single character change. Word mode groups changes by words (best for prose). Line mode compares entire lines (best for code or structured text).
Can I compare large files?
Yes, the tool handles large text files limited only by your browser's memory. For very large files, line mode provides better performance than character mode.
