What is Human Design?
Human Design is a synthesis of astrology, the I Ching, the Kabbalah, the Hindu chakra system and quantum physics. Your chart shows how energy moves through you: which centers are consistently defined, which are open and conditioned by others, and how to make decisions that fit your design.
Astreya calculates both the Personality (your birth moment) and the Design (roughly 88 days earlier in solar arc), then draws your BodyGraph and unpacks its meaning in clear, modern English. Pair it with your natal chart for a truly integrated self-portrait.
Frequently asked questions
Is the Human Design chart free?
Yes. Astreya generates your BodyGraph — type, strategy, authority, profile, defined centers, channels and gates — for free. A deeper AI reading is an optional paid upgrade.
How accurate is the calculation?
We use Swiss-Ephemeris-grade planetary positions and the standard 88-degree solar-arc offset between Personality (birth) and Design (prenatal) calculations.
What information do I need?
Exact date, time and place of birth. Birth time matters — profile lines and several centers can flip within minutes.
Which Human Design system do you use?
The standard Ra Uru Hu system: five types (Manifestor, Generator, Manifesting Generator, Projector, Reflector), the 9 centers, 36 channels and 64 gates, plus the four authorities.
Can I combine it with my astrology chart?
Yes. Astreya lets you view your natal astrology and Human Design side by side, and the AI Synthesis tab weaves them into one coherent reading.
