How Health to AI works
Three steps from the Health app on your iPhone to a smarter conversation with your AI.
Choose what to share
Sign in with Apple (anonymously) and pick exactly which Apple Health data types to sync. Anything you don’t allow is never read.
Encrypt, then sync
Your records are summarized and encrypted on device with AES-256-GCM. The cloud only ever stores ciphertext.
Connect the AI you trust
Authorize ChatGPT, Claude, Gemini, Cursor or another compatible tool via MCP with OAuth or a read-only API key — then just ask.
Built for people who want AI to understand their health — privately
Apple Health already knows a lot about you. Health to AI is the secure bridge that lets your AI assistant use that context, on your terms.
Encrypt first, then sync
Health records are encrypted on your device before upload, and the data key stays in your iPhone’s Keychain.
- Check sync status and recent sync history at a glance
- Sync manually any time; background timing is managed by iOS
- No plaintext health data stored in the cloud
Choose exactly what you share
Explore 100+ supported health and fitness data types and switch each one on or off.
- Activity, sleep, heart, body measurements, nutrition, workouts, mindfulness
- Daily or hourly summaries, prepared on your device
- Availability depends on your device, iOS version and permissions
Connect AI you trust
Use MCP with OAuth, or create a read-only API key, for AI clients that support it.
- Works with ChatGPT, Claude, Gemini, Cursor and other MCP-capable tools
- See which AI read what, and when
- Revoke any single connection instantly
Stay in control
No advertising tracking. Your data is never sold or used for ads, profiling or model training by us.
- Delete your account and cloud data in the app
- Cloud data auto-deletes after 180 days without an authorized AI query
- Health to AI never writes to Apple Health
Works with the AI you already use
Connect through the open Model Context Protocol (MCP) with OAuth, or a read-only API key. Step-by-step guides:
Connection options depend on each AI service, your account and plan. Health to AI has no built-in chatbot — it brings your data to the AI you choose.
What you can ask once your AI has context
Real questions people ask after connecting Apple Health to their AI assistant.
100+ Apple Health data types, your choice
Share only what helps your AI help you. Examples of supported categories:
Activity
Steps, distance, flights climbed, active energy, exercise minutes

Sleep duration, stages (core, deep, REM), time in bed
Heart
Heart rate, resting heart rate, HRV, walking heart rate
Workouts

Privacy is the product, not a feature
Health data is sensitive. Health to AI was designed so that you decide what is shared, with whom, and for how long.
On-device encryption
AES-256-GCM before upload. The cloud stores ciphertext; plaintext API keys and data keys are never stored on the server.
Anonymous sign-in
Sign in with Apple provides an anonymous identifier. We don’t collect your name or email.
Explicit consent per AI
Access is granted only when you confirm a specific, named AI recipient. Syncing alone is never consent.
Read-only access
Connected AI tools can read the data you synced — they can’t change it, and nothing is written to Apple Health.
Access log & revoke
See recent reads by each AI (kept 90 days) and revoke any connection with one tap.
Automatic expiry
Cloud health data is deleted after 180 days without a successful authorized AI query. Delete everything instantly in Settings.
