AI Ground School is a browser game that teaches you to actually operate AI, not just read about it.

You work through ranks — Recruit to Architect — across 32 lessons and exams, doing real tasks and getting told when you get them wrong. It runs as a single HTML file: no account, no install, nothing leaves your browser.

The first two ranks are free. After that it's a one-time $19.99 with lifetime updates.

One design decision worth knowing about: every lesson is tagged for portability — universal, concept, or Claude-specific — shown before you start it and before you buy. About half the curriculum transfers to any assistant. The rest covers tools that only exist in one place, and the game says which is which instead of pretending everything is universal.
