How to use Text Compare

01

Paste Your Texts

Enter the original text in the left panel and the modified text in the right panel, or upload files to auto-fill.

02

Compare Automatically

The tool instantly analyzes both texts and displays all differences highlighted line-by-line in real time.

03

Review & Export

Review the color-coded changes, copy specific differences, or download the full comparison report as needed.

Pro Tips

  • Use the 'Ignore Whitespace' option when comparing code or formatted text to focus only on content changes, not spacing differences.
  • Check character-level diffs for subtle changes like punctuation, capitalization, or single-word substitutions that line-view might miss.
  • Paste large documents directly into the tool-all processing happens locally, so size does not matter for privacy or speed.
  • Export comparison results in unified diff format to share with team members or integrate with version control workflows.
