Compare Text

Find the differences between two versions of a text, with the changed words marked inside each changed line. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.

How to do it

  1. Paste the first version.
  2. Paste the second version.
  3. Read what changed, marked in place.

Questions

Why mark individual words?

Because “this line changed” is not an answer when the line is a paragraph — you would still have to find the changed word by eye, which is the job.

Is colour the only thing telling me what changed?

No. Added lines carry a plus and removed lines a minus, so the result reads the same without relying on being able to distinguish the two tints.

Is my text uploaded?

No. The comparison runs in your browser.
