What is a Text Diff tool?

A text diff tool compares two pieces of text and highlights what was added, removed, or changed.

It is useful for editing, proofreading, SEO content review, programming, contracts, and checking changes between versions.

How to use the Text Diff tool

  1. Paste the first version of the text into the left field.
  2. Paste the second version into the right field.
  3. Optionally ignore whitespace or case differences.
  4. Enable inline mode if you want to highlight changes inside each line.
  5. Click Compare to see the differences.

Tips

  • Ignore whitespace when formatting changes are not important.
  • Ignore case when you only care about content, not capitalization.
  • Inline mode is useful for small edits within the same sentence.
  • Copy the result if you need to share the comparison.
