Stop paying your AI to guess
That's what a year of vague prompts can burn in failed round-trips. Every concept you actually know — the right component, the right query, the right ask — skips the guesswork. Fluency is the cheapest upgrade your AI subscription will ever get.
Rough math: ~2 avoided re-prompts (~5k tokens) per mastered concept, over a year of regular building.Five ways to learn
Quiz with combo multipliers, 60-second speed rounds, swipeable smart review, match pairs, and a daily challenge worth +100 XP.
Real spaced repetition
Cards you fumble come back sooner, cards you own come back later — 10 minutes to 21 days. The swipe queue always knows what's due.
Streaks, XP & a bouncy robot
Levels from Prompt Apprentice to Latent Space Legend, 16 badges, confetti, synthesized sound — and a mascot with genuinely good jump physics.
Prompts you can steal
Every card's back is a ready-to-paste AI prompt with a working example. Copy, paste, ship.
