A privacy-first, offline medical scribe powered by Gemma 4 E4B for global healthcare resilience.
Offline Clinical Reasoning at the Edge addresses the critical need for reliable AI in medical environments with poor or zero connectivity. In rural clinics, field hospitals, and disaster zones, cloud-based AI tools fail entirely, leaving doctors buried in paperwork with no intelligent assistance. This project solves that by deploying the Gemma 4B model locally via Ollama and mobile-edge infrastructure, enabling full AI-powered medical scribing with absolutely no internet access required.

This repository details the high-level architecture, hardware platforms, optimization methods, and performance benchmarks for running Gemma 4 E4B directly on edge hardware platforms for an offline, privacy-first clinical scribe application.
This architecture focuses on maximizing on-device processing for privacy and offline capability, leveraging Gemma 4 E4B's efficiency.
