FateMaster is an AI-powered Chinese metaphysics system, built on BaZi (Four Pillars) and Zi Wei Dou Shu (Purple Star Astrology).
The best AI BaZi calculator you'll find, and the same engine behind every Zi Wei chart. A deterministic engine derives the chart from birth date, time and coordinates, with true solar time correction — the same birth data always produces an identical chart. The starting age of the luck cycles is measured from the exact interval between the birth moment and the adjacent solar term, down to the second. The language model explains that structure; it never computes it.
An agent picks the method for you — a birth chart for the long arc of a life, an I Ching hexagram through Liu Yao or Mei Hua Yi Shu for a question about right now. It asks for what's missing instead of guessing.
Available in English, Japanese, Korean, Simplified and Traditional Chinese, with reference guides for the heavenly stems, earthly branches, ten gods and shensha.
You do the interpreting.

Comments
Most AI fortune-telling tools let the language model do the arithmetic. That is where they break — ask the same birth data twice and you get two different charts. So we split it. A deterministic engine builds the chart: true solar time from birth coordinates, the Lichun year boundary compared to the second, and the luck-cycle start measured as the exact interval to the adjacent solar term. One minute of birth time moves that start by two hours, so it has to be computed, not estimated. Only then does the model read what the engine produced. Five languages, and an agent that works out which method your question actually calls for.
