Why Sidereal
Our mission, our stance on AI, and what the name means.
As a family, we have always been very spiritual people. With Sidereal, our hope is to teach about astrology and spread love & light, as well as learn about ourselves along the way — to give others something to relate to, and to help guide them on their own spiritual journeys. Astrology here is a tool to help people connect with themselves and learn about the “why” behind life’s mysteries.
The name was not chosen randomly: sidereal means “relating to the stars or constellations”. That is exactly what we are trying to do — relate your life’s experiences to the stars, to provide clarity on things that might not seem totally clear otherwise.
A teacher, not a substitute for you
Sidereal uses AI to read your chart and answer your questions. The chart itself is cast by the Swiss Ephemeris — the same planetary math professional astrologers rely on, and it would say the same thing with the power off. We are not using AI to do the thinking for us — we use it as a teacher, one that knows real planetary mathematics and can explain them patiently. Once you have asked a question, it is up to you whether to heed what it says. Intuition takes precedence here; trust your gut and your own gifts.
What reaches Anthropic to make that possible — your chart, your question, and what the Seer remembers of your life — and what never leaves us, is set out plainly in our privacy policy. Anthropic does not use it to train its models.
Not everyone can afford a professional reading — with Sidereal, you can learn what you need to know about astrology in an affordable, easy-to-understand way. When a reading uses a term you don’t know, just ask — the Seer glosses as it goes, and can turn your own wheel to the very thing it speaks of.
