PharmaBridge

Voice-first AI medical rep. WhatsApp + Offline app. Drug info anytime, anywhere.

Inspiration

In rural India, doctors see 50+ patients daily with unreliable internet and zero time to type queries into drug databases. Medical representatives visit once a month — but drug interactions matter at the moment of prescription. We asked: what if every doctor had a 24/7 AI medical rep in their pocket?

What it does

PharmaBridge is a voice-first AI medical representative that works everywhere:

Online Mode: Doctors send a WhatsApp voice note asking about drugs, dosages, or interactions. Our cloud AI responds with voice + text in seconds.
Offline Mode: A lightweight Android app with on-device inference. No internet? No problem. Ask via voice, get instant answers locally.

When connectivity returns, everything syncs — usage logs, updated drug databases, new interactions.

How we'll build it

WhatsApp Business API for voice note ingestion
Speech-to-text (Whisper) and text-to-speech pipeline
RAG architecture with medical knowledge base (drug interactions, dosages, contraindications)
Quantized on-device LLM (Phi-3 mini) for offline inference
SQLite + vector DB for local drug storage
Sync protocol with conflict resolution for seamless online/offline transitions

Challenges we anticipate

Ensuring medical accuracy with hallucination guardrails
Optimizing LLM for edge devices with limited RAM
Handling voice in noisy clinic environments
Designing sync logic for intermittent connectivity

What makes it unique

No app downloads for WhatsApp mode. No internet needed for offline mode. Voice-native — because doctors don't have time to type. Built for the real world, not demo day.
