Clean Code

How to Read the Diff Output

Our tool uses standard visual cues to show you exactly what has changed between your two text samples:

  • Red Background: This content exists in the Original text but was removed in the New text.
  • Green Background: This content did not exist in the Original text and was added to the New text.
  • Plain Text: Content that has remained exactly the same across both versions.
