Hidden Stems is a Bazi / Four Pillars chart tool that helps users generate a free birth chart, understand their Day Master, Five Elements, hidden stems, and luck cycles, and optionally unlock a deeper AI-assisted reading.
It is designed for people who are curious about Chinese astrology but do not want to start with a dense textbook or a spreadsheet-like calculator. The product keeps the original Chinese stems and branches visible while explaining the chart in plain English.
