Daovian
Transparent AI Chinese Metaphysics — built to be checked.
Rules you can recompute. Conclusions you can open to their sources. AI explains — it does not invent verdicts.
Email magic-link sign-in. Charts, rules, and AI explain are free for now — no payment required.
Why transparent
Most tools sell black-box destiny. We show the chart facts, the open rules, and the passages behind an explanation.
Black-box fortune
Opaque scores, unverifiable claims, no trail from conclusion to rule.
Verifiable reference
Reproducible engine output, cited sources, AI limited to explanation.
How it works
Three layers. Only the last one is language — never the calculation.
Engine
Deterministic calendar and chart math — stems, branches, solar terms, chart construction. Same inputs, same facts. No model call on this path.
Sources
Open classic passages and curated claims, linked from explanations. If we cannot cite, we show facts without forcing a verdict.
AI explain
Narrates engine results plus retrieved citations. Translates and clarifies — never invents new destiny math.
The verification trail
Every strong claim should survive three checks — the same contract as our method page.
01 · Recompute the fact
Identical birth data and timezone policy → identical chart / day facts.
02 · Open the rule or passage
Explanations point to algorithm rules or classic sources — not vibe.
03 · Bound the model
AI may narrate inside that fence. Outside it, we stay silent or label uncertainty.

Today is the product home: almanac notes you can inspect, plus — when you have a main chart — day relationships the calculation can explain. Built for return visits, not a one-time spectacle. Optional digests stay optional.
