Frequently Asked Questions
Q: How does AI text detection work?
A: AI detectors analyze patterns in writing such as word choice, sentence structure, predictability, and perplexity. AI-generated text tends to be more statistically predictable than human writing.
Q: Is AI text detection 100% accurate?
A: No. AI detectors are not perfectly accurate and can produce false positives. Use them as a guide, not as definitive proof of AI-generated content.
