Like Duolingo, but for critical thinking.

Critical thinking for the age of AI. Fermigo is the daily thinking game for kids aged 6–9.

Why it matters now

In a world of instant answers, kids need to learn how to think.

AI can answer almost anything. But kids still need to question, reason, and solve problems on their own. Fermigo makes that feel like play.
