Frequently asked questions
How accurate is detection?
No detector is 100% accurate. Treat results as indicators, not proof. False positives occur.
What is perplexity?
How predictable text is. AI tends to be more predictable (lower perplexity) than humans.
Can AI text be undetectable?
Edited AI text or mixed human/AI writing is harder to detect. Results are probabilistic.
