TOOLS · DIFF

Compare two texts and see every change.

Paste the original and the changed version. Lines that were added appear in green, and lines that were removed appear in red.

+ And runs away.

When This Helps

  • Checking what changed between two drafts of an essay or contract.
  • Reviewing a config file before and after an edit.
  • Comparing two versions of a JSON or code snippet.

How This Tool Works

The comparison is done line by line with the diff library, in your browser. Nothing you paste is sent to a server.
