About Stellaro

Stellaro.net computes birth charts and Human Design bodygraphs –
precisely, from the Swiss Ephemeris – and then has an AI read the result back to you in
plain language.

What the site does

You enter date, time and place. From that we build the chart: planetary positions,
houses, aspects – and, if you want it, the Human Design bodygraph with gates, channels
and centres. The maths runs on the Swiss Ephemeris, the standard of astrological
software; positions are accurate to arcseconds. Four frameworks sit side by side:
Western astrology, Vedic astrology (Jyotish), Human Design and its sidereal variant.

Calculating is one half. Reading is the other: what stands in the chart is described
and connected, in text you can follow without technical vocabulary.

The reading comes from an AI

The calculation is astronomy, and therefore checkable. The reading is not. It is
produced by a language model that has read the astrological tradition and shapes a text
from it – which is why there is no objective right or wrong in it. The same configuration
can be read in different ways; two runs may emphasise different things. Take the texts as
an invitation to think, not as a statement of fact. What is precise are the numbers
behind them.

Why true constellations – an experiment

Part of the site does not use the familiar zodiac but the actual boundaries of the
constellations in the sky. The thought behind it: if you take astrology seriously, then
you assume there is such a thing as a cosmic quality – one that exists above as it does
below. And if that is meant seriously, you have to go back to the root: to what is
physically out there in space. The classical signs are twelve equal segments, an order on
paper. The constellations are unequal, irregularly bounded – and real.

Whether better readings come out of it is an open question. This is explicitly an
experiment, and it is allowed to be fun. It stands beside the established methods, not in
their place.

Who stands behind this

I am Reinhard Fritz, and everything on this site is my own view – not a doctrine.

I built Stellaro.net for myself first. I wanted one place where Human Design and the astrological methods sit side by side in a single calculator: to compare, and to play. Not to find out which of them is “the right one” – honestly, that question interests me less than looking at the same birth through four different lenses.

The experiment with the true constellation boundaries comes from the same direction: I think a cosmic quality shows itself in the large as in the small – and if you take that seriously, it is worth going back to the root, to what actually stands in the sky. It stays experimental all the same, and it is labelled as such.
