You don't need to memorize prompts. You need to see — with your own eyes — what your words actually produce. Kotoba Dojo turns that into a game.
Free to try · No credit card required
Every AI course hands you a list of "magic prompts" and calls it a day. You paste them, they work once, and the moment your situation changes — you're lost again.
The real skill isn't memorizing prompts. It's expressing exactly what's in your head, in words an AI can act on. That's a muscle. And muscles grow through reading training.
You're shown an image. Your job: describe it so precisely that an AI could recreate it from your words alone.
Say it out loud or type it — no character limits, no tricks. The AI generates an image from exactly what you said.
Your result appears next to the target. The master scores you, shows what you missed, and what you nailed. Score 80+ to advance.
Prove you can direct AI through a full real-world task, end to end.
Handle ambiguity: vague goals, missing information, changing requirements.
Ship something real, built entirely by directing AI. The final proof.
