How znakai astrology produces a reading: precise math via Swiss Ephemeris, a disciplined interpretation method, and a voice that talks to you like a friend.

This page describes how we produce a reading.

Two layers: math and language

From your birth date, time, and place we compute exact planetary positions, house placements, and aspect angles. The astronomy runs on Swiss Ephemeris — the same high-precision ephemeris (based on NASA’s JPL data) used by astro.com and professional astrologers, accurate to fractions of an arc-second.

The interpretive layer is a large language model. What makes it work is precise math plus a disciplined interpretation method: how to read aspects, which orbs to use, how to handle stelliums, and how to hold the voice.

A friend’s voice

Specific over vague, conversational over aspirational, confident without pleading. We say: “Saturn in your 6th house — that’s why growing up feels tied to work.” The discipline is part of the method and is reproducible regardless of which model is used.

Open pricing

FAQ

01 How precise is the math?
The astronomy (planetary positions) is exact math from Swiss Ephemeris, accurate to fractions of an arc-second. The reading is built on those exact coordinates.
02 What does the chart say about the year ahead?
Transits to your natal chart show which themes the coming year brings into focus. The natal-portrait PDF gives them a chapter of their own — the lessons of the year.
03 Who writes the interpretation?
A large language model with an astrological interpretation method writes the text. The planetary positions are computed by a separate astronomical layer, so the model doesn’t invent coordinates.
