MANIFESTO
Anygua isn't fortune-telling,
it's an instrument that makes the act of "drawing numbers" visible.
What's most interesting about the I Ching is not "what it predicts," but the combinatorial mathematics that three thousand years ago produced 2⁶ = 64 states, a logic of transformation, and a "drawing-of-numbers" lineage that runs unbroken from yarrow stalks to coins to SHA-256.
Anygua does this thoroughly: every method, every intermediate value, every step on every cast — reproducible in any language. Casting is free, unlimited, forever.
We do DO
- Implement all 8 casting methods — 4 traditional + 4 modern
- Show every intermediate value (hash, modulus, line position)
- Provide public-domain hexagram text for the 64 archives
- Use cryptographic-grade randomness for coin / yarrow
- Allow anonymous casting; sign-in is only for cross-device save
We don't do DO NOT
- Predict fortune, score luck, or rate days
- Read faces, names, or birth charts
- Sell talismans, blessings, or rituals
- Send "daily horoscope" emails
- Sell or share your castings with anyone
What is this?
Is Anygua a fortune-telling app?
No. Anygua treats casting as a math/probability exercise; every result is shown with its full computation. We do not tell you when you'll be rich.
How is it different from existing I Ching apps?
Most apps wrap a generic LLM around a one-button "cast." Anygua treats the casting engine itself as the product — 8 transparent methods, no fortune theater.
How do I cast?
Do I need incense, candles, or sincerity?
No. Each method is a defined procedure. Choose one, enter the input, press Cast.
What's the difference between "From Text" and "From Verse"?
Technically both go through the same SHA-256 pipeline; "From Verse" provides poem-friendly UI affordances and example presets.
What does the math guarantee?
Will the same input always produce the same hexagram?
Yes for the four modern methods (text / verse / music / image) — that's the point of determinism. No for traditional methods, since coins and yarrow use cryptographic randomness.
Do the coin and yarrow methods actually have different probability distributions?
Yes. Coin: 6/7/8/9 = 1/8, 3/8, 3/8, 1/8. Yarrow: 1/16, 5/16, 7/16, 3/16. Both implemented faithfully.
Data & privacy
Do I have to sign in to cast?
No — anonymous casting works fine. Castings are not persisted across devices without an account.
Are uploaded images/audio kept?
For MVP, the server reads the bytes for casting only and does not persist the file. We keep the hexagram, the filename, the byte count, and a hash fragment.
Pricing
Is there a paid tier?
Casting is always free and unlimited. Deep reading archives (full public-domain commentaries) unlock per hexagram.
