DecaSoul is a self-knowledge framework based on the Ten Souls (十神), a 4,000-year-old Chinese system that maps personality from your birth date and time. Take a free two-minute test at www.decasoul.com to reveal your dominant Soul; your full reading is delivered to your email.

Is the Ten Souls system the same as astrology or MBTI?

It is distinct. Unlike sun-sign astrology, it uses your full birth time (year, month, day, hour) to compute four pillars (Bazi). Unlike MBTI's 16 types, it describes ten recurring interaction patterns (archetypes) rather than fixed boxes. DecaSoul frames it as a reflection tool, not a prediction.

Bazi vs Apps

Nebula vs the 东方MBTI

Nebula is an AI astrology app that generates horoscopes and astrologer-style chats from your natal chart. The 东方MBTI (DecaSoul) derives ten stable archetypes from the Four Pillars (八字) using an open-source algorithm.

Both are birth-data-driven, but Nebula optimizes for daily engagement, while the 东方MBTI's result is fixed the moment you are born — it does not change from day to day.

Daily AI vs fixed framework

Nebula generates new fortunes every day through a closed AI model. The 东方MBTI gives you one verifiable answer that stays true, computed from a 4,000-year Chinese system historically used for matchmaking and career counsel.

Frequently asked

Is Nebula more accurate than Bazi?

They answer different questions. Nebula produces daily AI-generated astrology; Bazi computes a stable personality pattern from your birth time. One is a daily feed, the other is a fixed framework.

Why does the 东方MBTI never change?

Because it is computed from your birth data, not generated by a model. The same birth time always produces the same Four Pillars and dominant Ten Soul.
