About CosmoMind
CosmoMind teaches children how to think, not just what to memorise. Every mystery asks you to guess first, offers hints if you need them, and only then reveals the real science. That guess is the thinking muscle — and it's a skill that lasts far longer than any exam.
“Make people use logic and think for themselves — not just pass a test.”
CosmoMind collects no personal data and has no accounts. Any progress is saved privately in your own browser and never leaves your device.
Where the facts come from
The science is checked against trusted, openly-licensed sources — and always written in our own words, never copied. Every mystery carries a credit line so you know it's real fact, not opinion.
