One-time top-up, no auto-renew. With any positive balance, casting becomes unlimited and does not consume any credit. Once your daily AI interpretation quota is used up, each further interpretation costs 1 credit.
Yarrow Yi is a daily I Ching reflection companion for anyone interested in the wisdom of change. We pair the classical Book of Changes with thoughtful AI interpretation — today's hexagram, a question coach, line-by-line readings, and a journal you can read back later.
No. The AI only interprets. Your hexagram comes from a random process (3-coin) or a fixed method (Plum-Blossom by time, or manual numbers) — objective and reproducible.
Casting itself is local — your hexagram is generated by a random or fixed method, no AI call involved, so the quota is generous (exactly 10× the interpretation quota: 10/100/500). AI interpretation calls the model and uses your daily plan quota (1/10/50). After it is used up, AI Credits cover further interpretations at 1 credit each. While you hold any AI Credit balance at all, casting becomes unlimited and does not consume any credit.
