The birth chart: a unique photograph of the sky at the moment you were born
Your birth date, time, and place hide a map you've been carrying without knowing it
We calculate your birth chart instantly with real astronomical data and explain your three pillars — sun, moon, and ascendant. If you want to go further, you can generate an AI analysis trained on Silvia Susach's method.
Includes an explanation of your sun sign, ascendant, and moon
Your chart and its analysis are generated through an AI tool specifically trained on Silvia Susach's method and work. It's a guide to start getting to know yourself and understanding your birth chart better, but it doesn't replace a human interpretation. If you'd like to go deeper into your chart and your current moment in life, you can always book an individual consultation with our team.
Most people are seriously wrong about what a birth chart actually is
When you think of astrology, you're probably thinking of your sun sign:
“I'm an Aries”
“I'm a Sagittarius”
“I'm a Gemini”
And that's fine: it's a gateway.
But it's also why astrology often seems to fall short.
Maybe you've read things about your sign and thought, "Yes… but not quite."
Maybe you've met two people with the same sign who are nothing alike.
Maybe you have decisions and reactions of your own that make you wonder: "Why do I always end up like this?"
The answers are always in the birth chart.
Your birth chart isn't your horoscope. It's the map of how the sky looked the moment you were born: the Sun, the Moon, the Ascendant, and the rest of the positions that make up your unique astrological configuration, calculated from your birth date, time, and place.
That's why it's extremely rare to find two identical birth charts.
And that's why two people with the same sign can be so different.
The birth chart doesn't predict what will happen to you either, or box you into "that's just how you are."
It's the foundation from which you can start reading how you react, what you need emotionally, how you connect with others, and what patterns you repeat.
That's what changes when you stop looking only at your sun sign and start looking at the whole chart.
The three pillars of your birth chart
Your free chart already includes an explanation of your three natal pillars:
☀️
Sun
It's the sign you already know.
Even if it isn't always the one that best describes you. It speaks to how you think and make sense of what you experience: your particular way of seeing things.
🌙
Moon
It's your most emotional side.
The one almost no one sees at first glance. It speaks to how you feel, how you handle it, and what you need to feel secure.
↑
Ascendant
It's the first impression you give.
How you present yourself, how others perceive you at first, and the way you tend to start things.
Some of the things your birth chart talks about
Your character
There are traits of who you are that go far beyond your sun sign. Your birth chart captures the specific combination behind how you react, decide, and relate to others.
Your essence
There's a part of you that stays there even as you change jobs, partners, cities, or life stages. Your birth chart speaks to that foundation: what moves you, what matters to you, and what you need to feel like yourself.
Your life purpose
Your birth chart points to themes that repeat along your path and experiences that help you grow. It doesn't tell you what to do with your life, but it does show which situations repeat to teach you something specific.
Where your calling shines
Not every job, project, or environment brings out the best in you. Your birth chart holds clues about what kinds of activities activate your energy and what ways of working suit you best.
How you are in relationships
Your birth chart speaks to how you connect: what you need to feel secure, how you experience intimacy, and what you look for when you choose someone. It also reveals what dynamics tend to repeat in your relationships.
Patterns you repeat
Sometimes you react, choose, or protect yourself in a way you repeat over and over, without being fully aware of it. Your birth chart points to that tendency so you can start recognizing it when it shows up in your decisions, emotions, or relationships.
Your relationship with money
Money isn't only about numbers. Your birth chart holds information about how you experience security, self-worth, deservingness, and the way you manage your resources.
How you are within your family
Not everyone understands home the same way. Your birth chart speaks to your relationship with family, roots, care, and what you need to feel you belong.
And much more about you than you ever imagined.

Astroteca is a tool created together with Silvia Susach, founder of Comunidad Astral, Spain's largest astrology membership
From law to astrology: the less conventional path
Silvia studied law and for years moved in environments where rigor, logic, and "sensible" decisions carried the most weight. From the outside, everything matched what was expected of her: good education, stable jobs, international experience... But inside, something never quite fit.
Working with people, the common thread running through it all
Legal work, tourism, human resources, recruiting… Silvia moved through very different fields, but they all shared something: an interest in understanding people. That's where astrology started to fit in as a tool for understanding patterns, needs, bonds, and ways of living.
A hobby that grew bigger than she imagined
In 2019 she started talking about astrology on Instagram while juggling other jobs. She shared what she knew clearly, directly, and grounded in real life. No sensationalism, mysticism, or fear-mongering.
2022: the year of the big decision
The birth of her son marked the turning point. She could no longer juggle work, her project, and motherhood without sacrificing real time with him. So she left the security of stability behind and bet everything on astrology.
From Instagram to Comunidad Astral, a book, and the media
Today Silvia runs Comunidad Astral, Spain's largest astrology membership; she has over 46K followers on Instagram, has published an introductory book on astrology, and has appeared in the media sharing her way of understanding this tool for self-knowledge.
