Free Text Compare
Loading the tool…
Paste two versions of a text to highlight what was added, removed or kept — word by word or line by line — with a similarity score.
See exactly what changed

Options let you ignore case or extra spacing. The comparison runs in your browser, so private text never leaves your device.
