Text Diff Checker
Paste two versions of text and see exactly what changed — line by line.
How to Use
- Paste your original text in the left panel and your modified text in the right panel.
- Optionally enable Ignore case or Ignore whitespace for a looser comparison.
- Click Compare to see the diff result.
- Green lines are additions, red lines are deletions, and plain lines are unchanged.
