Pick where to start: all you'll need is a birth date, time, and place.
Sun, Moon, and Ascendant, planets by sign and house, the aspects between them — explained in plain language, no astrology jargon. You'll see at a glance where your strengths lie and where your familiar sore spot is.

We overlay your chart on your partner's and look at what's genuinely there between you: a shared language, warmth, attraction, alignment on what matters — and what holds a couple together for years, not just the first six months.

In short — what you brought with you into this world. The Sun is about what truly matters to you and where you're drawn. The Moon is about feelings, habits, and what helps you feel at ease. The Ascendant is about how people read you at first meeting, before you've said a word. The rest of the planets file away your mind, love, drive, and stubbornness — each trait on its own shelf.
"A chart isn't read for fate, but for how you're built."
The houses show where those traits speak loudest: in work, in money, in close relationships, at home. The aspects — the angles between planets — explain why some sides of you live in harmony while others argue their whole lives. That's how a living person comes together, not just a Sun-sign label from your feed.
Reading a chart is easier than it seems. Start with three — Sun, Moon, Ascendant: they already reveal a great deal. Then look at where it hurts right now — the chart will point to the strength you can lean on. And you always have daily horoscopes, Tarot spreads, and a lunar calendar at hand.

The essentials
It's a snapshot of the sky at the moment you were born: where the Sun, Moon, and planets sat across the signs and houses, and the angles they made to one another. Together this builds a portrait of your character, your strengths, and the recurring themes of your life. The chart doesn't promise specific events — it shows the potential within you and how to work with it.
Your time of birth determines the Ascendant and the entire layout of the houses — and that's a good half of the chart's meaning. The sky turns about one degree every four minutes, so even fifteen minutes can shift the Ascendant into the neighboring sign. We can calculate the planets' positions without an exact time, but for the full picture it's best to check the hour on your birth certificate.
The Ascendant is the sign that was rising on the horizon at the moment you were born. It governs first impressions: how people read you before you say a word, and how you instinctively step into a new situation. That's why the Ascendant is often more noticeable than your headline Sun sign — and why it needs an exact birth time.
We draw the planets' positions from precise astronomical tables — the same ones behind the professional software astrologers use. Houses are calculated with the classic Placidus system. That means the positions of the luminaries in your chart will match a professional calculation; any difference lies in interpretation, not in the astronomy itself.
Yes. You can build both your personal chart and a compatibility reading for free, with no sign-up and no hidden conditions. Everything is calculated right in your browser: your date, time, and place of birth never leave your device and stay only with you.
Chart compatibility (synastry) overlays two complete natal charts onto each other, rather than comparing two Sun signs. We look at the real angles between your planets and your partner's: where there's warmth and a shared language, where there's attraction, and where you'll need to learn to truly listen. That makes it far more accurate than any "Aries + Libra" table — it accounts for both partners' Moon, Venus, Mars, and Ascendant, not just one sign from a horoscope.
Start typing the name — suggestions appear as you go, and you can use Latin letters too. If your place still isn't there, pick the nearest large city or enter the coordinates by hand: what matters for the chart is latitude, longitude, and time zone, not the exact address. It barely affects the result — neighboring towns produce an almost identical chart.
