How it works

Does it compare word-by-word or character-by-character?

Both — it highlights word-level changes by default, with character-level precision within changed words.

Can I compare entire documents?

Yes, paste large blocks of text and scroll through the highlighted differences side by side.

Count words, characters and reading time.
