How to use it
- Paste the original on the left and the new version on the right, or open a file on each side.
- Read the result: removed text is red, added text is green, and changed words are highlighted inside each line.
- 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.
