Market Brain - AI that explains why Indian markets move — daily

Hey Product Hunt! 👋 I'm Himanshu, Sr. Tech Lead from India. I built Market Brain over 3 weeks — nights and weekends after office hours. The moment that sparked this: I was watching CNBC when a Fed meeting was about to happen. Everyone around me seemed to understand what it meant. I had no idea how a decision made in Washington would affect my Nifty SIPs, my IT stocks, my home loan EMI. I Googled for 30 minutes. Got 10 articles. Still confused. That frustration became Market Brain. The core insight: most finance apps show you WHAT happened. Nobody explains WHY — and specifically, what it means for Indian markets and Indian investors. What I built under the hood: - 6 AI agents running in sequence — extract events, build causal chains, map India impact, narrate, verify, format - A dedicated verifier agent that catches hallucinations before they reach you - Math engine in pure Python — AI never touches a number - Precise NSE index tracking — Nifty PSU Bank vs Private Bank move differently, the AI now knows this - Morning brief (8 AM) + Evening recap (4:30 PM) with accuracy tracking Would love your feedback — especially from fellow engineers who also invest and feel confused by macro. 🔗 market-brain.vercel.app
