Shunshi.AI is an AI-powered Bazi (八字 / Chinese Four Pillars of Destiny) reading platform. Enter a birth date, time, and location, and get an accurate, in-depth astrology chart

explained in plain language — in English, Traditional Chinese, Simplified Chinese, Japanese, or Korean.

What makes it different

Correct math. Built-in true solar time (真太陽時) correction and proper handling of the 子時 (23:00–01:00) day-pillar boundary — two things most English-language Bazi tools get wrong.

Parity-tested. Chart calculations verified character-by-character against professional-grade Chinese tools.

5 languages, not translations. Each locale has its own terminology, explanations, and cultural framing — not machine-translated English.

AI interpretation. The chart is the starting point; the AI layer explains what each pillar, element, and relationship actually means for career, relationships, and timing.

Open source

Two libraries power Shunshi.AI and are published as npm packages anyone can use:

shunshi-bazi-core — TypeScript library for Bazi calculation with true solar time and 子時 handling.

shunshi-bazi-mcp — MCP server that lets any AI agent (Claude, Cursor, Windsurf, etc.) read a Bazi chart natively.

Pricing

Freemium: 3 readings per day for free. Paid passes start at $1.99/day, $3.99/week, $9.99/month.

Stack

Next.js, TypeScript, Supabase, Vercel, Cloudflare, AWS.

Who it's for

People curious about Chinese astrology who want a modern, accurate, multilingual tool.

Developers integrating divination or cultural content into AI agents via MCP.

Readers and practitioners who need correct chart math, not approximations.
