AI Health Export vs ChatGPT Health: Which Is Right for You?
ChatGPT can now read your Apple Health data directly. But sending your most personal health information to OpenAI's servers isn't the only option. Here's an honest comparison so you can decide which approach fits your needs.
Two different approaches to AI health analysis
Both tools let you use AI to understand your Apple Health data, but they take fundamentally different approaches to where your data goes and how it gets processed.
AI Health Export
An iPhone app that reads your Apple Health data locally, processes it on your device with on-device AI, and gives you the option to export clean CSV files to any AI tool you choose. Your data never touches a server unless you decide to share it.
ChatGPT Health
A feature built into the ChatGPT app that connects directly to Apple HealthKit and sends your health data to OpenAI's servers for analysis by GPT. It works within the ChatGPT conversation interface.
Side-by-side comparison

Data stays within ChatGPT. No export option.
Pro plan. Or $39.99/yr. Free tier with 7 days and 20 metrics.
Basic features free. ChatGPT Plus required for GPT-4o analysis.
On-device AI runs without an internet connection.
All processing happens on OpenAI's servers.
On-device AI + export to Claude, GPT-4o, Gemini, and more.

The privacy question
This is the biggest difference between the two tools. Health data is some of the most sensitive information you have -- it includes your heart rate patterns, sleep habits, menstrual cycles, medications, and more. Where that data goes matters.
ChatGPT Health sends your Apple Health data to OpenAI's servers for processing. OpenAI's privacy policy governs how that data is stored and used. By default, conversations may be used to improve their models unless you opt out.
AI Health Export processes everything on your iPhone by default. The on-device AI never sends your data anywhere. If you choose to export a CSV and upload it to an external AI tool, that's your decision -- but the default is completely private.
Why privacy-first matters for health data
- 1.Health data can reveal conditions you haven't disclosed to anyone
- 2.Once data is on a server, you lose control over its long-term storage and use
- 3.Data breaches at major tech companies are not hypothetical -- they happen regularly
- 4.On-device processing means there's nothing to breach -- the data never leaves your phone
Data portability: own your data or rent access to it
With ChatGPT Health, your health analysis lives inside ChatGPT conversations. You can't take the structured data to another AI tool, load it into a spreadsheet, or share it with your doctor in a standard format.
AI Health Export gives you CSV files -- the universal data format. Upload them to ChatGPT if you want, or use Claude for a second opinion, or open them in Google Sheets for your own analysis. You can also share a clean summary with your healthcare provider. The data belongs to you, in a format that works everywhere.
Any AI Tool
ChatGPT, Claude, Gemini, Copilot, or local models
Any Spreadsheet
Excel, Google Sheets, Numbers, or data analysis tools

When to choose each tool
Choose AI Health Export if you...
- Want your health data to stay on your device by default
- Need to track a wide range of metrics (87 available, including HRV, blood pressure, nutrition, and sleep stages)
- Want the flexibility to use multiple AI tools -- Claude for deep analysis, GPT-4o for visualization, Gemini for a different perspective
- Need CSV exports for spreadsheets, personal records, or sharing with a doctor
- Want AI analysis that works without an internet connection
- Care about data portability and not being locked into a single platform
Choose ChatGPT Health if you...
- Already pay for ChatGPT Plus and want health analysis included at no extra cost
- Are comfortable with your health data being sent to OpenAI's servers
- Only need basic health metrics analyzed (steps, heart rate, sleep duration)
- Prefer a conversational interface and don't need data exports
- Want the simplest possible setup with no separate app
Why using multiple AI models matters
Different AI models have different strengths. Claude excels at careful, nuanced analysis and long-context reasoning. GPT-4o is strong at data visualization and code generation. Gemini integrates well with Google's ecosystem. By exporting your health data as a CSV, you're free to use whichever AI gives you the best insights -- or use several for a more complete picture.
ChatGPT Health locks you into GPT models. If a different AI is better at spotting patterns in your sleep data or correlating your HRV with exercise recovery, you have no way to get a second opinion without manually re-entering data.
AI Health Export also includes a built-in on-device AI that runs entirely on your iPhone. This means you can get health insights immediately, with zero data leaving your device, and then optionally export to more powerful cloud-based models for deeper analysis.
Works without internet
AI Health Export's on-device AI runs completely offline. Traveling, in airplane mode, or just don't want to connect to Wi-Fi? You can still analyze your health data, review trends, and export CSV files. ChatGPT Health requires an active internet connection for every interaction because all processing happens on OpenAI's servers.
