What it is
You have data in Apple Health, Oura, Whoop, Libre, MyFitnessPal, your lab portal, and a Notes app full of symptoms. None of them talk to each other. APIs are a nightmare. Exports are CSVs that take a weekend.
This workflow uses one AI tool and your phone's screenshot folder to build a single, structured ledger across every source — no integrations, no API keys, no engineer. You drop in screenshots, the prompts extract structured rows (date, metric, value, unit, source, note), and the AI returns a clean Markdown or CSV ledger you can paste into Notion, Sheets, or the Wellness & AI app.
Includes the screenshot-naming convention that doubles extraction accuracy, the extraction prompt with strict schemas (so the AI stops hallucinating units), a deduplication prompt for overlapping sources, and a weekly review prompt that turns the ledger into one paragraph you can show a clinician.
Who it's for
For people running their own AI Health Stack.
Best for
- You already collect data from a tracker, lab, or app and want to read it yourself.
- You're tired of one-app dashboards and want a system you control.
- You're comfortable pasting prompts into Claude, ChatGPT or Gemini.
Not the right fit if
- You want a single app that decides everything for you.
- You're looking for medical advice — this is a personal-knowledge tool.
