Microsoft opened a waitlist Thursday for Copilot Health, an isolated section of its Copilot chatbot designed to pull together medical records, wearable data, and lab results into a single AI-readable profile. The service connects to over 50 wearable devices (Apple Health, Oura, Fitbit among them) and taps electronic health records from more than 50,000 U.S. hospitals through a partnership with HealthEx.
The pitch: Copilot Health takes scattered health data and surfaces patterns a user might miss on their own, then helps them prep better questions for actual doctor visits. Responses pull from sources verified by a panel of 230-plus physicians across 24 countries and include citations alongside answer cards from Harvard Health. Microsoft says Copilot already fields 50 million health queries a day, so this formalizes something millions of people were already doing informally.
Mustafa Suleyman, Microsoft's AI chief, called it "first steps towards a medical superintelligence," which is a bold framing for a tool that explicitly disclaims being medical advice. The company stresses that Copilot Health runs in an encrypted, isolated environment, separate from general Copilot chats. Health data won't be used for model training. Microsoft holds ISO/IEC 42001 certification for the platform.
The timing is crowded. OpenAI launched ChatGPT Health in January, and Amazon expanded its own health chatbot this week. Copilot Health is available via waitlist to U.S. adults only, in English, with broader rollout planned later.
Bottom Line
Microsoft is third to market behind OpenAI and Amazon, but bets its integration with 50,000-plus hospital systems via HealthEx gives it an edge in data breadth.
