About this tool
Compare two pieces of text line by line to review edits, drafts, snippets, and generated content changes.

How to use Text Diff
Paste the original and updated text, review the highlighted changes, and then use the diff to decide what actually changed before sharing or approving the revision. If whitespace or line breaks matter, compare the raw versions first so the output reflects the exact kind of change you care about.
