Relationship astrology
Compare two birth charts with a compatibility calculator: see synastry aspects, house overlays and relationship dynamics, then ask AI about your actual charts.
Editorial review by Luis PhamMethodology
Compatibility compares two calculated natal charts. It can show cross-chart aspects and, when birth times are available, house overlays and angle contacts. It is a reflective tool, not a fixed score or prediction about a relationship.
Planetary positions, aspects and supported house overlays are calculated from the supplied birth data rather than inferred by AI. Interpretation is a separate reflective layer.
Cross-chart aspects (how one person's planets touch the other's), house overlays (where a partner's planets land in your life areas), and contacts to your chart angles.
Houses and chart angles need an accurate birth time. If a time is unknown we still show planet-to-planet compatibility and leave out anything that would require the missing time — rather than guessing.
Start with calculated contacts, then add the life-area and angle context that the inputs support. This keeps a Sun-sign snapshot or one dramatic aspect from becoming a relationship verdict.
Let the engine calculate both natal charts before interpreting the relationship.
Read the planets, aspect geometry and orb behind attraction, emotion or friction.
When both times are reliable, use houses and angles to ask where the interaction lands.

Ask About Us
Compare both charts, then ask AI about your relationship — attraction, communication, emotional needs, conflict, or recurring patterns. AI reads the two charts together — how cross-aspects and overlays interact — not a generic Sun-sign match.
These pages explain one Sun-sign pairing as a starting point — not a match score and not a substitute for two full charts. Read a guide, then compare both birth charts to see the synastry you actually have.
Two people with the same Sun sign share a style, while the rest of both charts supplies the difference.
Shared element gives the pair a common operating language without making their expression identical.
Polarity can create complementarity and friction, but the signs alone do not establish an exact aspect.
A shared pace can help coordination or make the same kind of pressure repeat from both sides.
Different elements and modalities make translation, timing and explicit requests especially important.
