Frequently asked questions

Can AI writing detectors tell me who wrote something?

Not reliably. Detectors produce false positives on human writing, especially by non-native English writers, and are easy to fool with light editing. Never use a detector score alone to accuse someone.

Where do the passages come from?

The human passages are short excerpts from public-domain books and documents, credited after each answer. The AI passages were written for this game by Claude, an AI model, in October 2026.
