OFFICIAL CHATGPT ASSISTANT
Cast your chart inside ChatGPT
Most assistants answer a Zi Wei Dou Shu question by describing the system. Ours casts the actual chart — it calls the same calculation engine this site runs on, so the palaces you get in chat are the palaces you get here.
Open the assistant in ChatGPT →How to use it
- 1Open the assistantIt is a public GPT — no key, no signup with us.
- 2Give it your birth detailsDate, time (or the two-hour 时辰) and the city you were born in. Birthplace matters: the chart is corrected to true solar time, which depends on longitude.
- 3Read the chart it castsMain star and its rarity, all twelve palaces, the Four Pillars, your Day Master and the five-element balance.
Where the readings come from
The chart itself is calculated, not generated — the same deterministic engine, from the same birth data, returns the same chart every time. The interpretations this site publishes are rule-based on 15 classical texts rather than written fresh by a language model; the full bibliography is public.
See the source list at /sources, or the calculation endpoint the assistant calls at /api-docs.
What it will not do
- · It casts the chart and explains the structure. The chapter-by-chapter written reading is a separate paid product on this site, and the assistant will point you here rather than improvise one.
- · It quotes no prices. Sign in here to see what a reading costs; nothing is charged inside ChatGPT.
- · It stores nothing. Birth details sent to the calculation endpoint are used for that one chart and never written to our database.
- · Zi Wei Dou Shu and BaZi are traditional symbolic systems offered for reflection, not verified prediction.
