Fitbit AI Coach to Read Medical Records in US Preview
SkimNews Take
Wearable data piped into AI coaches creates a feedback loop where the more users share, the sharper the personalization—and the harder it becomes to switch platforms, locking patients into whichever tech giant aggregates their full health history first.

- Google announced Fitbit's AI health coach will read users' medical records—lab results, medications, and visit history—starting in preview for US users next month, following Amazon, OpenAI, and Microsoft into consumer health AI.
- Google health intelligence PM director Florence Thng said combining medical data with wearable data will yield "safer, more relevant and more personalized" advice, but a disclaimer states the coach "is not intended to use your medical records to diagnose, treat, cure, prevent, or monitor any disease or condition."
- Fitbit will let users securely share records and AI summaries with family or health providers via link or QR code in the coming months, with Google stressing the data won't be used for ads and that users control sharing and deletion.
- Fitbit's sleep tracking is getting a separate 15% accuracy boost to better distinguish actual sleep from time spent trying to sleep, rolling out in preview over the next few days with an improved sleep score to follow.
- Anthropic and OpenAI explicitly encourage users to share health data with Claude and ChatGPT, while Oura and Woop run dedicated health chatbots—a competitive rush the article notes is potentially "treading a fine line" with regulators like the FDA.
- Many AI-based health products aren't yet available in Europe under stringent privacy laws, and experts warn users should be careful with what they share, "doubly" so for reproductive data in America.
Why it matters: Google is feeding lab results and medication histories into a consumer AI that is legally barred from diagnosing or treating disease but marketed as delivering personalized wellness advice. That gap between what the disclaimers forbid and what the product promises—and the fact that EU privacy law already keeps comparable products out of Europe—makes regulatory friction, not technical capability, the binding constraint on this category.
