Usage Guide
The text diff checker highlights additions, deletions, and unchanged parts between two text versions. It is useful for document revisions, config changes, translation review, prompt iteration, and small code snippets. Put the old version on the left and the new version on the right, then run the comparison to inspect removed and added segments. For clearer results, keep formatting similar on both sides: normalize line breaks, indentation, and spaces first. If formatting differs too much, the diff may emphasize whitespace noise instead of meaningful content changes.
