Your birth chart — also called your natal chart — is a map of the sky at the exact moment you were born. Every planet was in a specific sign and house. The relationships between them (called aspects) create a completely unique pattern that describes who you are: how you think, love, work, heal, and evolve.
Unlike a generic horoscope based only on your sun sign, a birth chart reading takes into account your moon sign (your emotional inner world), your rising sign (how you show up in the world), and the placement of every other planet — Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto — in your chart.

How it works
From Birth Data to Personalized Reading
Stellara uses your birth date, birth time, and birth city to calculate your complete natal chart — including your rising sign (which requires a precise birth time). Once your chart is calculated, Claude (Anthropic's AI) generates your personalized readings, grounded in your specific planetary placements.
Every reading is written fresh for your chart. Not a template with your name swapped in — a genuine interpretation of your exact planetary blueprint, written in the style you prefer: psychological, spiritual, modern, or classical.
Common Questions
Birth Chart FAQ
Do I need to know my exact birth time?
Your birth time is needed to calculate your rising sign and houses. Without it, Stellara can still read your sun and moon signs — but the rising sign and house placements won't be accurate. Check your birth certificate, or ask a parent. Even an approximate time (morning, afternoon, evening) helps narrow it down.
How is this different from a generic horoscope?
A generic horoscope is written for everyone born in the same 30-day window — roughly 1 in 12 people on the planet. Your natal chart is unique to the exact minute and location of your birth. Stellara reads your chart and writes to its specific placements, not a sign-wide average.
What does "personalized based on rising sign" mean?
Your rising sign determines your house system — which life areas each zodiac sign governs. Two Scorpios born on the same day but at different times can have completely different rising signs, meaning Aries rules career for one but creativity for another. Your rising sign makes the reading specifically yours.
Can AI really interpret a birth chart accurately?
Stellara uses Claude, one of the most capable AI models available, trained on a vast body of astrological knowledge. It interprets your planetary placements, sign combinations, and current transits to produce readings that professional astrologers recognize as accurate and nuanced. Many users find them more personal than readings they've paid hundreds of dollars for.
What's the difference between a one-time reading and the daily horoscope?
The Natal Birth Chart reading covers the timeless landscape of your chart — who you are, how you love, what drives you. The daily horoscope does the same thing but through the lens of what's happening in the sky today: which planets are activating your chart, what the transits mean for you right now. Pro subscribers get both, every morning.
