Paste two versions of a text to see exactly what changed. Removed parts are struck through in red, added parts are highlighted in green, and a summary tells you how much changed.
Compare by lines for code and config files, by words for essays and contracts, or by characters to spot single-letter typos. Everything is compared in your browser – nothing is uploaded.
Questions
Can I compare code?
Yes. Line mode works well for source code, JSON and config files.
Is there a size limit?
Texts of several thousand lines compare in under a second. Character mode is slower on very large texts.
Is my text private?
Yes. The comparison runs in your browser and the text is never sent anywhere.
