Frequently asked questions

How is the difference displayed?

The visible comparison highlights word-level additions and removals.

How is the percentage calculated?

The percentage uses case-insensitive Levenshtein edit distance across the two character strings. It is an estimate, not a plagiarism score.

Does the text leave my browser?

The comparison runs in your browser. KairoxBuild does not intentionally upload the two text blocks to an account or content database.
