What is a Text Diff Checker?

A diff checker compares two pieces of text and highlights the differences between them - useful for reviewing edits, comparing versions of code or copy, or checking what changed in a document. Added content is shown in green, removed content in red.

How to use it

  • 1. Paste the original text on the left and the changed text on the right.
  • 2. Choose how to compare - by line, word or character - and optionally ignore case or whitespace.
  • 3. Review the highlighted result, then copy or download it.
