NatalChart.AI

NatalChart.AI is an online service that generates natal charts and provides AI-powered astrological interpretations grounded in precise astronomical calculations. It addresses the need for accurate, data-driven astrological self-reflection by first computing chart positions with the Swiss Ephemeris before generating any interpretive text.

The service calculates every planet, house cusp, and aspect to arc-second accuracy using the Swiss Ephemeris, the same library employed in professional astrology software. Users receive readings organized into six life spheres: Self, Heart, Body, Matter, Roots, and Mind. Each sphere includes a score derived from actual placements along with interpretations that explicitly cite the relevant aspects or positions rather than generic zodiac descriptions. Additional capabilities include live transits overlaid on the chart, solar return reports for any selected year, electional scoring over periods of 7, 14, or 30 days, and synastry analysis for compatibility with others. Readings are available in eight languages: English, Ukrainian, Russian, Spanish, Portuguese, Hindi, Chinese, and Korean.

The process begins with entry of birth data consisting of date, time to the minute if known, and city of birth. If the exact time is unavailable, the service defaults to noon and notes which chart elements depend on precise timing. Computation occurs server-side, delivering the chart wheel, Sun, Moon, Rising sign, and sphere scores within seconds. Users can then query the AI about any aspect of the chart, with each response tied back to the computed data. Charts and readings can be shared via public links that allow recipients to generate their own charts for free.

Access requires no signup for basic chart creation, sphere readings, and limited daily AI queries. A subscription unlocks higher daily message limits, saved compatibility connections, relocation astrology, expanded solar return options, and electional timing features. The service frames astrology strictly as a reflective language for noticing personal patterns and trade-offs, not as a predictive, diagnostic, or deterministic system, and it emphasizes that all interpretations derive from the ephemeris-derived chart data passed to the language model.
