Market Brain
AI that explains why Indian markets move — daily
I watched CNBC during a Fed meeting and had no idea what it meant for my Indian portfolio. How does a Fed rate cut affect Nifty? Which sectors benefit? I couldn't find a simple answer. So I built one. Market Brain explains WHY Indian markets move — daily. → 6 AI agents scan 70+ sources every morning → Causal chains: Event → India sector impact → Ask it anything about markets Free. No login. Just reasoning.
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.
