Start by understanding yourself.
Your birth chart reveals who you really are: your inner conflicts, what you expect from life, how you love, and what you need in a relationship. Built from real astronomical data, not generalizations.
Generate your birth chart freeNo credit card required. Your birth chart, always free.
Your sun sign is only 10% of who you are.
Most people know their sign. Few know what their birth chart actually says: how their emotional Moon works, what their Venus looks for in a relationship, how their Mars acts in conflict.
That information exists. No one had shown it to you in a way that made sense.
Your birth chart. Free.
Enter your date, time, and place of birth. Constelios calculates your exact planetary positions and generates your complete birth chart — the starting point for truly understanding yourself.
- Your Sun, Moon, and Ascendant — the three pillars of your personality
- The positions of Venus, Mars, and your personal planets

What about your partner?
Once you know how your chart works, the next question is natural: how does it interact with theirs?
Constelios' compatibility analysis goes beyond "you're compatible." It reveals the real dynamics of your relationship: where you connect deeply, where the recurring friction lives, and what you need to work on together.
