Frequently Asked Questions

Horary is the branch of astrology that answers a specific question from a chart cast for the moment the question is asked, at the place it is asked. The ruler of the Ascendant stands for you, the ruler of the house of the matter stands for what you ask about, and the aspects between them show whether and how it comes about.

No. Horary uses the chart of the question, not your birth chart, so AstroGPT never asks for your birth data.

One concrete question about a matter you genuinely care about right now: "Will I get the job I interviewed for?", "Should I accept this offer?", "Will we sign the lease?", "Where is my lost ring?". Very broad questions, two questions in one, or questions about other people’s private affairs are hard to judge.

Traditionally, no: ask again when the situation has changed, not because you didn’t like the answer. A repeated question gets a new chart, and the tradition holds that it says less than the first.

It is not a substitute for a doctor, lawyer or financial adviser, and it won’t predict death, trading results or lottery numbers. AstroGPT is for reflection and entertainment only.

When you start a chat, the app takes the current time and your location and calculates the chart with the Swiss Ephemeris, which reproduces NASA JPL’s planetary ephemeris to well under an arcsecond. In the Western tradition it uses the tropical zodiac, geocentric positions and Equal houses from the Ascendant, with the Sun, Moon and planets out to Pluto, Chiron and the true Node. The Vedic chart is described below.

Yes. In the app’s menu, under Astrology tradition, you can switch between Western horary and Vedic Prashna; in India, Nepal, Sri Lanka, Bangladesh and Pakistan the app suggests Vedic first. The Vedic chart uses the sidereal zodiac with the Lahiri ayanamsa, whole-sign houses from the Lagna and the nine grahas, Rahu and Ketu included, with their nakshatras and padas, graha drishti and dignities. The reading follows Prashna: the Lagna and its lord, the bhava of the matter and its lord, and the Moon. If the outcome looks unfavourable, it may suggest a simple remedy such as a mantra, a fast or charity — never gemstones or paid rituals.

The Ascendant and the houses depend on where on Earth the question is asked. The app reads your location from the phone when you start a chat; a city-level position is plenty, since a few kilometres move the Ascendant by only a fraction of a degree.

The chart is calculated, not generated: the positions are exact. The reading is written by an AI language model instructed in traditional horary astrology (or, in Vedic mode, Prashna), and each answer explains the houses, rulers and aspects it relies on so you can follow the reasoning. Like any interpretation it can be wrong.

The sky moves: the Ascendant changes sign roughly every two hours. You can ask follow-up questions about the same chart for up to an hour; after that, start a new chat and a new chart is cast for the new moment.

The app is available in nine languages: English, Spanish, Portuguese, German, French, Italian, Russian, Turkish and Hindi, with Latin American Spanish and Brazilian Portuguese versions. Ask in any language you like — AstroGPT answers in the language of your question.

Yes. You start with free trial questions, and once you’ve used them you can earn more by watching a short ad. AstroGPT Pro, a subscription, gives you a much higher daily limit without ads.

The iPhone app is coming soon to the App Store. Until then, AstroGPT is available on Google Play for Android.

There are no accounts, and your questions and answers are not stored: the conversation lives only in the app while the chat is open and is sent over an encrypted (TLS) connection with each message. To write the answer, the question and its chart — but not your location coordinates or device identifier — go to our AI provider, OpenAI, which doesn’t use them to train its models. We don’t sell your data. See our Privacy Policy for details.

There is no account to delete, and your chats aren’t stored. To remove what the app keeps on your phone, clear its storage in Android settings or uninstall it (on iPhone, delete the app); you can also reset your advertising ID in Android settings or turn off tracking in iPhone settings. Our server keeps only question counters and technical logs linked to a device identifier, not to your name. For any questions, email support@astrogpt.me.
