How to use it

  1. Paste the original on the left and the new version on the right, or open a file on each side.
  2. Read the result: removed text is red, added text is green, and changed words are highlighted inside each line.
  3. Switch between side by side and unified views, and ignore spacing or capital letters if they do not matter to you.

What it’s for

Seeing what someone changed in a contract or a shared document, comparing two versions of a config file or a piece of code, or checking an edited essay against the draft. It runs entirely in your browser, so private documents never leave your computer.
