Ba-Zi.ai's answer

Built as a tool we ourselves wanted to use. After paying for a human BaZi master reading that felt generic and vague, we wondered if modern LLMs — properly prompted with classical BaZi theory (子平真诠, 滴天髓, 穷通宝鉴) — could produce chart-grounded readings accessible to anyone. The result: a free tool that combines rigorous metaphysical framework (Day Master balance, Ten Gods, Luck Pillars) with the scale and price of AI. The viral SBTI personality test was added as a gateway for users unfamiliar with BaZi to experience chart-based insight.

Ba-Zi.ai's answer

People making decisions — whether to accept a job offer, whether a relationship is worth committing to, when to make a career move. They're culturally curious about Chinese metaphysics, often overseas Chinese, Taiwan, and Southeast Asian users aged 22-45. They've found MBTI too shallow and Western horoscopes too generic, but don't want to pay $200 for a master reading. Demographics skew female (60-65%) and tech-literate. They share their chart results in group chats.

Ba-Zi.ai's answer

Traditional BaZi masters charge $100–500 per reading and take days to deliver. Generic astrology apps give horoscope-level depth. Ba-Zi.ai sits between — free, instant, and chart-grounded with professional depth. Unlike most BaZi calculators that stop at a chart image, we deliver AI-generated interpretation across love, career, and timing that you can ask follow-up questions about. Multi-language (English, 简体, 繁體) and built mobile-first, so overseas Chinese, Taiwan, and Southeast Asia users get native experiences.

Ba-Zi.ai's answer

Every insight is anchored to specific elements in your actual BaZi chart — Day Master strength, Ten Gods interactions, Luck Pillars, Flow Year triggers — rather than generic horoscope language. We combine 1,000 years of Chinese metaphysical theory with modern LLMs that are explicitly prompted to cite chart facts, so you get concrete explanations like "your 丙火 day master is weak in autumn, 木 becomes your Yong Shen" instead of vague "love is in the air" predictions. Three interconnected tools — BaZi calculator, couple compatibility, and the viral SBTI personality test — share the same chart engine.
