Frequently asked questions
Does it compare line by line or word by word?Word by word — this catches small in-sentence edits that a line-level diff would miss.
Can I compare code instead of prose?You can paste code, but this tool isn't syntax-aware, so it treats code the same as any other text.
Is there a size limit?No hard limit, but very large texts may take a moment longer to compare since the comparison runs in your browser.
