What does the detector score mean?

The score is an estimate of how likely a classifier thinks your text is AI-generated, shown as a percentage with a band: Likely human, Uncertain, or Likely AI. It's based on how predictable and uniform the text is, not on any knowledge of who wrote it.

Scores are estimates from third-party classifiers and change as those tools update. No text can be guaranteed to pass any detector. Use the score to improve your writing, and follow your institution's or employer's rules on AI use.
