衍象坊 is an online toolset and content platform that brings together research into Chinese traditional metaphysics, the digitisation of classical texts, and artificial intelligence. Qimen Dunjia, Da Liuren, Liuyao, Dayan Shifa, BaZi (both the Ziping structural method and the Blind School work method), Zi Wei Dou Shu, Qizheng Siyu, Taiyi and Wuyun Liuqi can all be cast and studied here — in the browser, with nothing to install.

Alongside the charting tools we offer astronomy and calendar utilities — true solar time conversion, the sexagenary calendar, solar terms and lunar phases, sky maps and historical celestial-event lookups — and a growing library of sources: full texts of transmitted classics, plates of excavated bamboo and silk manuscripts shown beside their transcriptions, source-text analysis, and encyclopaedias of terminology and imagery. The aim is that every conclusion can be traced back to the original text or the underlying astronomical data.

On top of that, 衍象坊 uses AI to interpret chart results and to power character divination, face reading, agents and role-play conversations. Our position is straightforward: this material is cultural heritage worth studying and enjoying, not a tool that decides anyone's fate. Everything here is offered for cultural research and entertainment only.
