Hi ProductHunt! 👋 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 — 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 → 13,503 extracted rules - Birth chart math is pure JS (VSOP87B + Lahiri ayanamsa + RAMC formula) — 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 Free at rekhai.in — would love your honest feedback, especially if you know Jyotish 🙏
