Natal Compass: Birth Chart

Natal Compass calculates your birth chart, also called a natal chart, from real astronomical data and explains it in plain language: your Sun, Moon and Rising sign, the planets, houses and aspects, and the transits crossing your chart today.

It is astrology for self-reflection. Not a sun-sign horoscope, and not a forecast of what will happen to you.

Sun signs use one placement. A chart uses all of them, plus the houses, the aspects between them, and the angles that only a birth time can place.

How it is made

The positions come first. Every placement, aspect and transit is calculated from ephemeris data on our servers, and the writing follows the numbers. The interpretation library was drafted with AI, then reviewed and corrected by a professional astrologer with more than 30 years of practice.

We mark which parts are AI written. That seemed like the minimum.

What it will not do

No fortune telling. No warnings about what is coming for you. A hard transit is a season to understand, and we will not dress one up as a threat to keep you opening the app.

Natal Compass is educational software for self-reflection. It describes tendencies, not certainties, and it does not offer medical, legal, financial or psychological advice.
