What is a Text Diff Checker?

A text diff checker is a comparison tool that identifies and highlights differences between two pieces of text. It's essential for developers tracking code changes, writers comparing document versions, and anyone who needs to spot what changed between two text versions. Our text diff checker supports three comparison modes: character-by-character for precise differences, word-by-word (recommended for most use cases), and line-by-line ideal for code and structured text. Features include visual highlighting (added in green, removed in red), live statistics showing counts of added/removed/unchanged elements, swap function, copy diff export, and side-by-side view. Perfect for code review, document editing, content updates, translation comparison, configuration files, and contract review. All processing happens in your browser for complete privacy.

  • Character Comparison: Compares text character by character for precise differences
  • Word Comparison: Compares text word by word (recommended for most use cases)
