  • Document Editing: Track changes in articles, essays, or documentation
  • Configuration Files: Compare config files before and after modifications
  • Legal Documents: Identify changes between contract versions
  • Data Migration: Verify data integrity during transfers
  • Translation Work: Compare original and translated content

Key Features

  • Real-time Comparison: Instant diff calculation as you type
  • Multiple View Modes: Side-by-side and inline comparison views
  • File Upload Support: Upload text files directly for comparison
  • Export Results: Download diff results as text files
  • Color-coded Changes: Easy identification of additions, deletions, and modifications
  • Statistics Dashboard: Detailed metrics about the differences found

How to Use

1. Input Text

Paste your original text in the left panel and the modified version in the right panel. You can also upload text files using the upload button.

2. Compare

Click the "Compare" button to analyze the differences. The tool will highlight all changes and provide detailed statistics.

3. Review & Export

Review the differences in your preferred view mode (side-by-side or inline) and export the results if needed.

Understanding the Output

Green: Added content (new text in the modified version)
Red: Removed content (deleted from the original)
Yellow: Modified content (changed between versions)
Gray: Unchanged content (identical in both versions)
Pro Tips:
  • • Use the inline view for detailed character-level changes
  • • Use side-by-side view for line-by-line comparison
  • • Upload files directly for large documents
  • • Export results to share with team members
  • • Use the swap feature to reverse the comparison

Performance Note

This tool uses advanced algorithms to efficiently compare large texts. For optimal performance with very large documents (>10,000 lines), consider breaking them into smaller sections or using specialized diff tools.
