Every metric you need to authenticate text with total clarity and zero black-box obscurity.
Calculates variance across sentence and clause lengths (B_sent = (std - mean) / (std + mean)) to instantly identify machine uniformity with zero API costs.
Inspect entire documents with interactive sentence-by-sentence color highlighting (Red for AI, Amber for Mixed, Green for Human).
Connect your OpenRouter account via 1-click PKCE OAuth. Use direct wholesale credits (~$0.0001/scan) with zero subscription lock-in.
