How does Client-Side Diff work?

This tool computes the differences between two strings using the Myer's Diff algorithm. By comparing the text directly inside your browser window, your source code, configuration files, and sensitive credentials never touch any external API, ensuring absolute privacy.

Diff Modes Explained

  • Line Diff: Compares files line-by-line. Perfect for source code file revisions and system configuration updates.
  • Word Diff: Compares files word-by-word. Ideal for prose, copy edits, document proofreading, or markdown content.
  • Character Diff: Highlights changes down to individual character letters, showing the most granular shifts, typos, or white-spaces.
