About Twelvera

Twelvera pairs daily horoscopes, numerology and a chat with a virtual astrologer with an actual calculation behind it, not just text a language model invents on the spot.

Planet positions, houses and aspects are computed by our own calculation engine. It draws on the JPL DE441 ephemeris — the same data NASA JPL publishes and uses to navigate its own spacecraft. It's not a guess or an approximation, it's an exact astronomical position for a given moment and place.

Numerology follows one named method, consistently, not a different one every time. The model receives the finished numbers and keywords and writes readable text from them — it never calculates anything on its own.
