How to compare two texts

Paste the original version on the left and the new version on the right. Differences are highlighted as you type: removed lines are red, added lines are green, and the exact words that changed inside a line are highlighted more strongly.

Lines, words or characters?

Lines is best for code, configuration files and lists. Words suits essays, contracts and articles where sentences are reworded. Characters finds tiny changes such as a single typo or punctuation mark.

Is it private?

Yes. The comparison runs entirely in your browser, so it's safe to compare contracts, source code or anything confidential.
