Show HN: I built an AI for divination practice

Hey HN,

For years, I've been studying divination systems like Tarot. My biggest frustration was the lack of objective feedback. How do you know if you're genuinely improving your interpretive skills, or just telling yourself a good story?

To solve this, I built a web app that provides verifiable practice against an AI.

The idea is based on an old training game. Here’s how it works:

The AI generates a secret (e.g., conceptually "hides" an object, or determines an outcome to a short story). You use your chosen divination method (Tarot, runes, astrology, anything) to figure out the secret. You get an immediate, black-and-white result: you were either right or wrong. This creates a tight feedback loop that forces you to be precise. It's a "gym" for your skills, away from subjective interpretation.

The platform is system-agnostic. It’s not about which tool is "real," but about providing a sandbox to test your ability to connect symbols to concrete outcomes.

I built this for myself because I'm an introvert and couldn't find a consistent practice partner, but I thought others in this niche might find it useful too.

I'd love to hear your thoughts.
