What Duetto does
Five ways to read the sky
Every reading starts from real astronomical positions computed for your birth date, time, and city — then an AI language model turns the chart into something you can actually use.
Natal chart
Sun, Moon, Ascendant, and every planet, placed by house and aspect from your exact birth moment. Natal readings are free.
Read more →Daily transits
Each day the planets touch points in your chart. Duetto picks the three that matter most today and can remind you at the hour you choose.
Read more →Synastry
Add someone's birth details and see how two charts talk to each other — where energy flows, where friction lives, what you each bring out in the other.
Read more →Composite chart
The "third" chart: the midpoint map that describes the relationship itself as an entity, rather than either person in it.

From a birth date to a reading
01 · Enter
Your birth data
Date, city, and — if you know it — the time of birth. Time sharpens the houses and the Ascendant, but it is optional.
02 · Compute
A real chart, not a sun sign
Our engine resolves your coordinates and time zone and computes planetary positions with the Swiss Ephemeris — the same data a working astrologer uses.
03 · Read
Plain language, your chart
An AI model reads the aspects, houses, and transits of that specific chart and writes it up without the jargon. Come back daily for transits.

Things people ask
Is this a horoscope?+
No. A horoscope is a sun-sign average written for millions of people. Duetto computes your actual natal chart from your birth date, time, and city, and reads that — including transits, synastry, and composite charts.How accurate can it be?+
The astronomy is exact: planetary positions come from the Swiss Ephemeris, the same data professional astrologers use. The interpretation is written by an AI language model, and astrology itself is not a science — treat a reading as a thoughtful prompt for reflection, not a verdict. Duetto is for entertainment.Where can I use Duetto?+
Today, as a Telegram Mini App — no install, no password. An iOS app is in development and will appear on the App Store once review is complete. The product speaks English, Russian, Spanish, and Brazilian Portuguese.What data do you need?+
A birth date, a birth city, and optionally a birth time. For synastry or a composite chart, the same for the other person. Nothing else is required.Is my birth data safe?+
Your name and all birth data are encrypted at the application layer with authenticated encryption, on top of storage-level encryption, and the primary database is hosted in the EEA. We never sell your data and our AI provider is contractually barred from training on it. You can delete everything from your profile at any time.What is free and what costs money?+
Natal readings are free, along with your first synastry reading and a three-day trial of daily transits. Beyond that, transits and further compatibility readings are paid — with Telegram Stars in the Mini App, or through App Store in-app purchases and subscriptions in the iOS app. Prices are always shown before you confirm, and subscriptions are cancelled in your Apple Account settings.
