Healthcare AI

Lets a nurse chart by talking instead of typing. Runs on the hospital’s own hardware, so patient data never leaves the building.

Problem

Clinical AI has to be useful without being careless.

Privacy, latency, and interpretability matter as much as the model does, and a nurse mid-shift will not wait on a round trip to someone else’s API.

Approach

I built a clinical assistant with hard privacy constraints: nothing leaves the device that doesn’t have to.

Local speech-to-text, self-hosted models, and an interface a nurse could use one-handed while doing something else.

How it works

A voice-first clinical assistant a nurse can use one-handed, mid-shift.

  1. Flutter and TypeScript application layer built around voice-first clinical workflows: tasks, reminders, and patient vitals.

  2. Self-hosted LLaMA 3.2 with a zero-API, on-device speech pipeline, so protected health information never leaves the device.

  3. Deployed and tested across Indiana hospitals.

Private speech, local models, real hospital testing

Screens

  • Home screen with a large microphone button under the prompt 'How can I help you today?', plus shortcuts to add a task or reminder and to view patient vitals

    Voice-first home screen. The microphone is the primary control.

  • Task and reminder list screen in the clinical assistant

    Tasks and reminders, dictated hands-free during a shift.

  • Patient vitals screen in the clinical assistant

    Patient vitals, captured without touching a keyboard.

Impact

Time nurses got back at the bedside instead of at a keyboard.
