ComboDiet

A lightweight website for comparing symptoms and diet notes across multiple conditions.

What it does

• Lets you enter each diagnosis or condition.
• Tracks symptoms for each one.
• Highlights overlapping symptoms shared by more than one condition.
• Summarizes repeated food themes and caution notes from the data you enter.
• Generates clinician questions to bring to an oncologist or registered dietitian.

Important safety note

This app does not generate a medically verified treatment diet. It only organizes the information entered by the user. Any cancer-related diet plan should be reviewed by a licensed clinician.

How to use it

1. For the basic local version, open index.html in a browser.
2. Add conditions manually.
3. Review the overlap analysis on the right.

Run locally

1. Create a local .env file based on .env.example.
2. Put a fresh OPENAI_API_KEY in that file.
3. Start the server with:

cp .env.example .env
npm start

4. Open http://127.0.0.1:3000.
5. Click Run AI Analysis after entering conditions.

Deploy for your sister

The easiest path is Render.

1. Put this project in a GitHub repo.
2. Make sure .env is not committed.
3. Create a new Render Web Service from the repo.
4. Render will detect render.yaml and use the included settings.
5. In Render, add a secret environment variable:

OPENAI_API_KEY=your_real_key_here

6. Deploy, then send your sister the Render URL.

Important privacy note

If your sister will enter real medical information, only share this app over a deployment you control and be thoughtful about who has access to the link and logs.

Good next steps

• Replace manual entry with a clinician-reviewed condition database.
• Add printable visit summaries.
• Add medication tracking and supplement warnings.
• Add secure storage if private health data will be saved long-term.
