How to use the Text Diff

Compare two versions of a text and see exactly what changed, with additions and deletions highlighted line by line.

Steps

  • Paste the original text and the modified text.
  • Click Compare. Lines that changed are shown with a − (removed) or + (added) marker and a tinted background.
  • Use Clear to reset.

The diff uses a longest-common-subsequence algorithm, ideal for spotting edits in code or documents.
