FateMaster

FateMaster is an AI workbench for Chinese traditional metaphysics: BaZi (Four Pillars), Zi Wei Dou Shu, Liu Yao, Mei Hua Yi Shu, Qi Men Dun Jia, Tarot and the Chinese almanac. The architecture is what separates it from AI-fortune-telling toys: a deterministic rules engine computes the chart first — solar terms, the 60 Jiazi cycle, true solar time correction, palace and star placement — and only then does the AI write the interpretation on top of correctly computed data. The site's stated attitude is refreshingly level-headed: inherit the tradition rationally, no superstition, no mystification, "everyone is the interpreter of their own fate."

Who it's for: practitioners and serious students of Chinese metaphysics who care whether the chart is actually correct (they know AI-computed charts are usually wrong in the solar-term edges), culturally curious users wanting a serious tool rather than entertainment, and the Jung-quoting introspective crowd the homepage courts. Free entry with $1-ish trial credits. For a tradition-based tool, the rules-first-then-AI design is exactly the right respect for both the craft and the reader.
