New: talk to your birth chart in ChatGPT and Claude
If you use ChatGPT or Claude every day, you have probably asked them something about astrology. The answer usually sounds polished and confident, and it is usually wrong in the detail that matters: your rising sign, the house a planet sits in, today's transit. The AI is not being careless. It simply does not compute the sky, it estimates.
Starting today, anyone with the Full Map on AstrologyApp can change that. You can connect your chart to the AI app you already use, and from then on the AI answers with your chart's real calculations.
What changes in practice
Before, to get the AI talking about your chart you had to paste your data into the conversation and hope it interpreted correctly. Now the connection is made once. When you ask "how is my day?", the AI queries your chart on AstrologyApp, gets today's sky computed for your birth date and city, and only then writes the answer.
A few things you can ask:
- How is my day? And my week?
- What does this month ask of me at work?
- Best day in the next three weeks to sign the contract?
- When is the next New Moon in my sign?
- How is my year from my birthday on?
- What does my Moon in the 8th house mean?
You talk in your own words. The AI receives your whole chart and answers like an astrologer who knows it by heart.
Who it is for
The conversation works with charts that have the Full Map. It is a one-time payment per chart, no subscription, and if you already bought it there is nothing more to pay. Charts without the Full Map stay out until you activate it.
Today it works in Claude (any plan, including free) and in ChatGPT (Plus or higher). It is in beta: connecting still takes a few steps, and we want to know where you got stuck, if you did.
How to connect
In Claude it is one tap: a button opens the app with everything filled in, you confirm, log in to your AstrologyApp account and that is it. In ChatGPT you open the plugins area, copy the address we show and paste it into three fields. The step by step with screenshots is on the page Your birth chart in ChatGPT and Claude.
Want to disconnect? Account, Connected apps, one tap. Or remove the app inside Claude or ChatGPT.
What we do not do
We do not read your conversations. They happen inside Claude or ChatGPT. We only hand over your chart's numbers when the AI asks, and we keep a record of which queries were made, never the text. The AI is yours, the calculations are ours.
Frequently asked questions
Do I have to pay anything?
Connecting costs nothing. Readings use each chart's Full Map, a one-time payment. If you already have it, you can use it now.
Does it work on the phone?
Yes. In Claude, the phone app is enough. In ChatGPT, setup happens on a computer and then works in the app as well.
What if the AI says something odd?
Ask again naming the chart: "using Lena's chart" or "with my connected chart". If it still looks wrong, reply to the announcement email or reach us through the site's contact page. It is a beta, and every report helps.
