How to Compare Two Texts (Find the Differences)

When you have two versions of something — a document draft, a config file, a block of copy — eyeballing the differences is slow and error-prone. A text-compare tool highlights exactly what changed. Kitolity does it in your browser.

Where a text diff helps

Reviewing edits between two drafts, spotting an accidental change in a config file, comparing two error messages or API responses, or checking what a collaborator changed when there’s no version control. It turns “something changed” into “exactly this changed.”

Is my text private?

Yes — the comparison runs entirely in your browser, so both versions of your text stay on your device.
