Enter both birth details, and the AI chart engine will analyze the planetary aspects between you, compute a compatibility score, and reveal the cosmic code behind your relationship
Choose the dimension you want to explore, and the chart will tailor your reading
Synastry is the astrological practice of laying two birth charts over each other. By analyzing the aspects formed between the two people's planets — conjunctions, trines, oppositions and more — it reveals natural harmony and friction in emotion, communication, and values. It is one of astrology's most classic tools for reading relationships.
Enter both birth dates (time and city optional). The chart engine computes each person's planetary positions, compares every cross-chart aspect, scores your compatibility across several dimensions, and generates a bi-wheel aspect chart with a written reading. Core planetary aspects are available even without a birth time.
Start with the radar of compatibility dimensions to find your strongest and weakest areas, then read the key aspect interpretations to see which two planets are at play. A high score doesn't guarantee a match, and a low score isn't a verdict — aspects describe patterns of interaction; how you nurture them is up to you.
Yes. The birth date alone is enough to position the major planets like the Sun and Moon, which covers the core cross-chart aspects. Birth time only refines the Ascendant and houses — a bonus, not a requirement.
Yes. Choose your relationship type in the first step (friends, crush, colleagues…), and the chart will tailor the reading to that dimension of your connection.
No. Nicknames are only used for display in the report — feel free to use aliases. Birth details are used solely for this chart calculation.
No. The score reflects how smoothly your energies interact, and lower dimensions usually point to lessons that need work. Many lasting relationships are complementary — treat the report as a map for understanding each other, not a verdict.
