What 12andus Astrology does in ChatGPT
The 12andus Astrology plugin creates astrology readings in ChatGPT from birth details. You add a person with their birth date, time and place, and it calculates their birth chart with planets, houses, aspects and retrograde positions. It then writes a reading about personality, relationships and work based on astrological tradition.
It also produces transit charts, which describe how current planetary positions relate to a birth chart, for periods from one day up to a year ahead. For two people it can make synastry charts, which compare both charts, and composite charts, which combine them, for romantic, family or business relationships.
You can save up to 50 people under your account so you do not need to re-enter their details. If a birth time is unknown, it leaves out the parts that depend on it. Astrology is a belief system, so treat readings as entertainment or reflection rather than predictions.
