Questions

How do I compare two versions of text?

Paste the original and changed text into their separate inputs. The result shows differences using the selected comparison level.

Should I compare text by words or characters?

Word comparison helps inspect rewritten phrases. Character comparison helps find small edits inside identifiers, numbers, or spelling.

Does a text difference explain why a change occurred?

No. The comparison identifies changes in the supplied strings. It does not determine author intent or whether the revised text is correct.
