Frequently asked questions

Onne is an AI-powered astrology platform that helps you understand yourself through personalized birth chart insights, daily horoscope cards, compatibility analysis, and meaningful connections with others aligned to your cosmic energy.

Onne uses Swiss Ephemeris — the same astronomical data used by professional astrologers — for precise planetary positions. Our compatibility algorithms analyze synastry aspects, cosmodynes, and harmonic patterns to deliver nuanced relationship insights.
