About Compare Diff

Compare Diff is an English-first, privacy-friendly text comparison tool built for quick code, configuration, checksum, and plain-text review. It compares text locally in your browser and keeps the interface focused on the editor.

The first version supports real-time side-by-side or stacked comparison, line, word, and character highlighting, local display preferences, optional syntax highlighting, unchanged section folding, and browser-side formatting for common structured text formats.
