This tool uses heuristic analysis of writing patterns for estimation. It is most reliable on longer text samples (100+ words) and should not be used as definitive proof of AI generation.
It analyzes burstiness (sentence length variation), pattern score (word perplexity/ predictability), and repetitiveness (word reuse frequency).
