This product was not featured by Product Hunt yet. It will not be visible on their landing page and won't be ranked (cannot win product of the day regardless of upvotes).
Cast six lines with three coins in the browser. A deterministic rules engine computes the six-line (liuyao) chart — eight-palace positions, Najia, six relatives, hidden lines, moving lines and the resulting hexagram — then an optional AI rewrites the explanation in plain language. It never picks the lines or changes the judgment. All 64 hexagrams readable in English and Spanish. Free, no account, history stays in your browser.
I built Agua after trying a few online I Ching tools: most either show a fixed block of hexagram text, or hand the whole reading to a language model and let it improvise. I wanted the opposite split.
So the coins and the chart are computed by a deterministic rules engine that follows the traditional six-line method. AI only rewrites the already-computed reading so it fits the question you asked, and it can answer follow-ups on the same hexagram. When AI is off, you get the rule-based reading.
Two things I deliberately kept boring: no account (your history is local to the browser), and an FAQ that spells out exactly what gets sent to the model provider when you use AI.
All 64 hexagrams are readable in English and Spanish; the origin is a Chinese-language tool.
What I'd most like to hear: did the reading make sense to you without knowing the terminology, and where did the flow lose you?

Agua was hunted by leon.kapi. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
