Symptom Checker AI

A quick hackathon demo app that turns a free-text symptom into a triage recommendation with a severity color bar.

Features

• Single demo user profile (pregnant 25 y/o with asthma).
• Uses OpenAI Responses API with Structured Outputs (JSON Schema) for reliable UI rendering.
• Visual green→red severity bar with a marker positioned by the triage level.

Setup

python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -r requirements.txt

# set your key (Mac/Linux)
export OPENAI_API_KEY="sk-..."
# Windows PowerShell:
# $env:OPENAI_API_KEY="sk-..."

# optional: choose a model
export OPENAI_MODEL="gpt-5"

Run

streamlit run app.py

Open the local URL in your browser. If no API key is set, the app will still run using a simple mock ruleset.

Notes

• uses healthcare databases
• For a real build, plug in a vetted medical content source and add stronger red-flag rules.
