KAXANTA
You want Eastern metaphysics integrated with your Western chart
K A X A N T A and Cosmic Copilot are the two AI-native astrology platforms most directly comparable in approach. Both ship deterministic chart math (Cosmic Copilot uses VSOP87; K A X A N T A uses NASA JPL via astronomy-engine) and both layer an AI guide on top. The difference is scope: Cosmic Copilot is a Western-astrology product with an AI assistant called Ask Cosmos and an astrocartography overlay; K A X A N T A is a multi-system platform that brings Human Design, Ba Zi, Numerology, Feng Shui, and four more Eastern traditions into the same chart, with The Architect AI reading across all nine. They are the same archetype — deterministic math + AI synthesis — applied to different surfaces.
You want Eastern metaphysics integrated with your Western chart
Western astrology is your primary interest and you don't need other traditions
| Aspect | KAXANTA | Cosmic Copilot |
|---|---|---|
| Calculation engine | NASA JPL ephemeris (astronomy-engine) + lunar-javascript for Chinese metaphysics | VSOP87 deterministic planetary positions |

| Astrocartography | Not yet — listed in the future roadmap (TASKS.md), not currently shipped | Built-in feature — a clear strength of Cosmic Copilot |
| Eastern systems | Six dedicated engines (Ba Zi, Zi Wei Dou Shu, Qi Men Dun Jia, Feng Shui, XKDG, Water Formula) plus Human Design | Not covered |
Cosmic Copilot is the closest direct comparable to K A X A N T A in product architecture: deterministic math + AI assistant. The differences are scope (Western-only vs nine-system), one feature each direction (astrocartography vs Eastern engines), and currency. If your astrology need is strictly Western and astrocartography matters, Cosmic Copilot may be the better fit. If you want the full nine-system blueprint with AI synthesis across them, K A X A N T A is purpose-built for that surface.
Not yet. Astrocartography is on the future roadmap but not in current scope. If astrocartography is a must-have for you on day one, Cosmic Copilot ships it today and is a clean fit for that need.
K A X A N T A uses the astronomy-engine library, which implements NASA JPL DE-440 ephemeris algorithms; Cosmic Copilot uses VSOP87. Both are well-established astronomical models with sub-arcminute precision for the core natal chart. For the planetary positions a Western chart needs, the difference is below the threshold any astrology methodology cares about.
Yes for cross-system questions; ask both for a single-system Western question and the answers will be of comparable quality. Where The Architect adds something different is when your Western-astrology question intersects with Ba Zi or Human Design or numerology — then the synthesis hierarchy kicks in and you get a multi-tradition answer Ask Cosmos isn't built to give.
