Hi ProductHunt! π I'm Karthik, the solo founder of Rekhai.
The problem I kept running into with AI astrology apps: they hallucinate. Ask ChatGPT about your Ashtakavarga and it makes something up.
Real Jyotish has thousands of specific rules in classical texts β things like "if Jupiter is in the 9th house in Cancer (exalted) with the 5th lord in kendra, the combination produces a Gajakesari Raj Yoga." Those rules exist in
Sanskrit manuscripts. I spent 12 months OCR-ing and extracting them.
**The tech:**
- 14 Sanskrit/Tamil manuscripts β 13,503 extracted rules
- Birth chart math is pure JS (VSOP87B + Lahiri ayanamsa + RAMC formula) β no AI involved in calculations
- Claude Sonnet writes interpretations using those rules as RAG context
- Vanilla JS PWA, Firebase, Cloudflare Worker proxy
**What's live today:**
- Palm reading (Samudrika Shastra)
- Full Vedic birth chart (Dasha, Navamsha, Ashtakavarga, 26+ Yogas, Doshas, Shadbala)
- Face reading (Mukhanga Shastra)
- Daily Panchangam with oracle
- Muhurtha Calculator (finds auspicious dates for marriage, travel, business)
- Tamil, Hindi and English
