A detector score is a statistical estimate, not proof of who wrote a text. Different detectors use different models, so the same text can score differently on each, and their models change over time.
We do not guarantee any score on any detector. If a completed rewrite scores below 90 on ours, the words are returned automatically once per document. If you think a result is wrong, tell us and include the document.
Send us a message and we will answer, usually within a day.
