Birth chart app with AI: the chart is calculated first, then the AI reads it

The Cosmic Codex is a birth chart app with AI that calculates your chart before the AI says a word. Your planets, houses and aspects come from the Swiss Ephemeris, and the AI answers from that calculated chart. Your chart is free; the AI conversation is part of Premium.

Calculated first

An AI can’t guess where the planets were when you were born. That’s arithmetic, and the Codex does it first: the Swiss Ephemeris, the tropical zodiac and Placidus houses. Your Human Design, Gene Keys and numerology are calculated from the same birth data and linked to it.

Test it on three placements you already know. If those are right, you can trust the ground the rest stands on.

Astrology profile: a natal chart wheel with signs, houses and aspect lines, beside a list of placements with sign, degree and house.

How the AI reads you

The Contemplation Chamber answers from your calculated chart: your placements and aspects, your Human Design gates and channels, your Gene Keys, your numerology and your transits. You can see the chart the Chamber reads from, in a panel beside the conversation. It offers guided contemplations as well as open questions. What rings true stays yours to decide.

If you’ve been pasting your placements into a chat and correcting it, here the groundwork is done before you ask: the chart is calculated and every tradition is linked.

What you get on the free plan

  • Your full chart in astrology, Human Design, the Gene Keys and numerology, calculated with the Swiss Ephemeris (tropical zodiac, Placidus houses), each linked to the others.
  • Your Sun reading: the first page of your Blueprint, written for you and unlocked.
  • The meaning of every placement in your chart, in each tradition.
  • Today’s sky, drawn with your chart.
  • The Library, with its pages linked to your chart.
  • Two profiles, so you can add someone you love.

What Premium adds

Premium opens the Contemplation Chamber (paid in AI tokens; there’s no free conversation), your Blueprint (a reading for every placement, kept on your profile), up to 10 profiles, two charts read side by side and your transits on your own chart.

Contemplation Chamber: a ring of rooms for Astrology, Alchemy, Numerology, Cosmic Embodiment, Human Design and Gene Keys around a Cross-system center.

Who built it

Felipe Poggi studied astrology, Human Design and the Gene Keys for years, each on its own, and kept knowledge bases to hold them together. The Codex is the tool he built to read his own chart whole.
