BaziFortune AI - AI BaZi fortune telling with Eastern metaphysics

Bazi Fortune AI brings the ancient Chinese Four Pillars (BaZi) system into a modern AI experience. Enter your birth details to generate a personalized BaZi chart, explore Five Elements, luck cycles, and key life patterns, then ask AI questions about your chart. Unlike traditional fortune-telling sites, it combines structured BaZi calculations with interactive AI explanations that are easier for anyone to understand.
