Tips & tricks
- Treat the verdict as a signal to investigate further, not a final judgment — AI detectors of any kind (including this one) produce false positives on heavily-edited human writing and false negatives on lightly-edited AI writing.
- Longer samples (300+ words) give the underlying model more writing-pattern signal to work with than the 100-word minimum — if a result feels uncertain, try it again with a longer excerpt from the same source.
- A 'Mixed' verdict usually means parts of the text read differently from each other stylistically, which can happen with legitimately human-written text that mixes quotes, paraphrase, and original writing — it isn't automatically a sign of AI editing.
