How the Text Diff Tool Works

Paste an original and a modified version of any text. The tool tokenizes both inputs into words and runs a Myers diff algorithm to find the minimal set of changes. Additions appear in green, deletions in red with a strikethrough, and unchanged words are shown normally.

  • Word-level diffing using the Myers algorithm
  • Color-coded output: green for additions, red for deletions
  • Shows counts of added, removed, and unchanged words

Everything runs in your browser. Your text is never sent to a server.
