What Cosine Astro offers

We calculate a birth chart from astronomical ephemeris data using the birth time and place you provide, and an AI answers your questions based on that chart.

What it is and isn't

Cosine Astro treats astrology as a cultural language for self-reflection. Chart readings are not scientific predictions. They don't predict fate or specific events, and they are not a substitute for medical, mental health, legal, investment or other professional advice. If you need that kind of help, please consult a qualified professional.

AI-generated content

Answers in conversations are generated by AI and labeled as such on the page. They may be inaccurate or incomplete. Use your own judgment, and don't make important decisions based on them.

Acceptable use

Please don't use automated tools to send questions in bulk, don't enter content that is illegal, infringes others' rights or involves other people's private information, and don't try to get around the question limits.

Changes to the service

We may change, pause or discontinue some features, including temporarily turning off AI readings when demand is too high. When these terms change, we'll note the date of the update on this page.
