Sajupalja
Integrated Four Pillars of Destiny & I Ching reference app with neutral, theory-based interpretations.
About
Sajupalja is an Android app that integrates Ziping Mingli (including Qiongtong Baojian) with the 64 hexagrams of the I Ching (Zhouyi). Unlike typical fortune apps that emphasize flattery and positive bias, Sajupalja uses a deterministic rule-based engine to compute charts and hexagrams, and delegates only the natural-language explanations to a self-hosted LLM (vLLM Gemma). Core calculations — divination methods (yarrow stalk, coin toss), perpetual calendar, pattern (Gyeokguk), and favorable element (Yongsin) — are never handled by AI.
