Frequently Asked Questions
What is Cosmic Copilot?

Cosmic Copilot differentiates on three axes: (1) Calculation precision — it uses VSOP87 ephemeris (the same planetary theory used by observatories), verified to ±0.001° against the Swiss Ephemeris; (2) Transparency — it shows WHY transits affect you, not just vague predictions; (3) Flexibility — it supports 10 house systems (Placidus, Whole Sign, Equal, Koch, etc.) vs 1 for most competitors.
