Synastry & Compatibility Calculator
Compare two natal charts and see what connects you with your partner. Synastry reveals the strengths of the union, tension zones, and interaction patterns — with a personal AI reading.
What is Synastry?
Synastry is an astrological method of comparing two natal charts. It shows how two people's energies intertwine: where they resonate, where they complement each other, and where conflict arises. Unlike simple "zodiac sign compatibility," synastry analyzes the mutual positions of all planets, houses, and aspects of both charts — giving a deep and personal result.
What You Get in the Reading
- Emotional compatibility — how the Moons interact: whether you feel safe with each other.
- Communication & intellect — Mercury aspects show how easily you understand each other and resolve conflicts through words.
- Love & values — Venus reveals what you value in relationships and how you express affection.
- Physical attraction & action — Mars shows the dynamics of initiative, passion, and potential arguments.
- Tension zones & growth — squares and oppositions indicate topics that require attention and dialogue for the relationship to grow.
How It Works
- Build your chart — enter your birth data and save the chart to your personal dashboard.
- Add a partner — enter the second person's birth data (date, time, place).
- AI analysis — the system compares the charts and generates a compatibility reading in plain language.
- Ask follow-up questions — in the dashboard, you can ask clarifying questions about the reading and get new insights.
