NATAL CHART
Your full birth chart in 60 seconds
Astraly calculates every planet, house, and aspect from real ephemerides — the same engine professional astrologers use — and explains what each one means for you in plain language.
Why Astraly is different
Professional-grade accuracy
VSOP87 ephemerides and Placidus houses — the same standard Astro.com and Solar Fire use. Accurate to under one arcminute. Not the simplified math most free calculators rely on.
Every point that matters
Sun through Pluto, Ascendant, Midheaven, North & South Nodes, Black Moon Lilith, Chiron — 14 points and 12 houses, not just "the Big Three". Most free tools stop at half of these.
Read in plain language
Tap any planet, house, or aspect to see what it actually means for you — written by an AI astrologer that's read your full chart, not a stock paragraph keyed to your sun sign.
How it works
- 1
Enter your birth data
Name, date, time, and city. If you don't know your exact birth time, Astraly works with an approximate time and flags which placements (Ascendant, houses) are tentative.
- 2
See your wheel
An interactive chart appears with your Sun, Moon, Ascendant highlighted at the top, every planet on the wheel, and aspect lines drawn in. Long-press any point for an instant reading.
- 3
Ask anything
"Why is my Moon in the 12th house lonely?", "What does my Venus square Saturn mean for relationships?" — the AI astrologer answers from your actual chart, not generic copy.
Frequently asked questions
What do I need to build my chart?
Your name, full birth date, your time of birth (if you have it), and the city you were born in. Astraly geocodes the city to longitude/latitude and looks up the historical time zone — no need to compute UTC offsets yourself.
What if I don't know my birth time?
You can still build the chart with an approximate time (e.g. "around noon" or "morning"). The Sun, Moon, and personal planets stay accurate to within a fraction of a degree, but the Ascendant, Midheaven, and house cusps are tentative — Astraly marks them as approximate so you know which readings to take with a grain of salt.
How accurate is the calculation?
We use VSOP87 series-B ephemerides (under 1 arcminute of error for every planet) and Placidus houses — the same algorithms running inside professional software like Solar Fire and Astro.com. Our values match theirs to within a few arcseconds; if you compare side-by-side, you'll see the placements line up.
Can I build charts for other people?
Yes. Your account supports multiple natal charts — partner, family, friends. Each chart lives in My Circle and can be opened, read, and compared against yours through the AI astrologer.
Is it free?
Building your chart is free and stays free. The AI interpretations of your chart, daily horoscope, and transits are also included on the free tier with a daily token allowance. Paid plans add unlimited AI conversations and additional charts.
Can I share my chart?
Yes — every chart has a Share button that produces a public link. The link renders a beautiful read-only view with the wheel + Big Three + planet table, with a rich preview that pastes nicely into Telegram, WhatsApp, iMessage and X.
How is this different from a Co-Star natal chart?
Co-Star is a shorthand chart with brief blurb per placement. Astraly gives you the full professional-grade chart (every planet, every house, every aspect) plus an AI that's been trained on 500 years of astrology corpus and can answer your actual questions — "why does this transit feel so heavy?" rather than a pre-written paragraph.
See your full chart in under a minute
Real ephemerides, every placement, every aspect — and an AI that reads them with you. Free to build, free to share.
