Frequently asked questions
How does the AI content detector work?

It analyzes sentence length variation, vocabulary diversity, and structural patterns. AI-generated text tends to have more uniform sentence lengths and less vocabulary variety.

Is the AI detector 100% accurate?

No. AI detectors are probabilistic, not definitive. Edited AI text is harder to detect. Use this as one signal among many.
