Frequently asked
Is my text sent anywhere?
No. The comparison runs entirely in your browser.
Which granularity should I use?
Words for prose or code you'd read line by line anyway; Lines when you care about which whole lines moved; Characters for short strings like IDs or slugs where a single-letter change matters.
Does this work offline?
