Free Online Text Diff & Compare Tool

Comparing two versions of code, config files, or documents is faster with a visual diff. Dokall highlights additions and deletions at the character, word, or line level so you can spot changes immediately.

Developers use text diff tools for code reviews, config audits, and merge conflict resolution. Paste both versions, pick a comparison mode, and review the highlighted output — all processed locally in your browser.
