Overview

## What True Sky does

Mastering the Zodiac LLC provides astrological chart computation in ChatGPT. The calculations cover natal charts with planetary positions, house cusps, and aspects; transits timed against a birth chart; synastry between two charts; composite midpoint charts; and solar and lunar returns.

Configuration is exposed rather than fixed. Seven house systems are supported, among them Placidus, Whole Sign, Koch, and Equal, along with eleven zodiac systems including Tropical, Lahiri, and True Sidereal. Asteroids can be added as an option.

The listing states a free allowance of 100 calculations per day. A prompt supplies birth date, time, and place, as in the example asking for a weekly horoscope from a 1985 Dallas birth.

### Who it is for

Astrologers and hobbyists who need particular house and zodiac settings rather than a generic reading.

### What stands out

House system, zodiac system, and asteroid options are all selectable, so a calculation can match a specific school of practice.

## Where True Sky is listed

True Sky is listed in the ChatGPT apps directory only. Mastering the Zodiac LLC has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
