八字 Bazi

A clean, privacy-respecting BaZi (Four Pillars of Destiny) charting tool.

• Complete charts: four pillars, hidden stems, ten gods, life stages, void branches, nayin, and symbolic stars - with solar and lunar (including leap month) input, and both late-Zi-hour conventions.
• Luck cycles: decade luck pillars, annual and monthly influences at a glance.
• On-device charts: calculations and saved cases stay on your device. No accounts, no ads, no analytics.
• Optional AI readings (bring your own key): when you choose an AI feature, relevant chart details and messages are sent directly to the AI provider you configure, such as OpenAI, Anthropic, or a compatible endpoint. Keys stay in system secure storage; requests never pass through our servers.
