Microsoft Healthcare AI Pulls From 50,000 Hospitals

Microsoft launched Copilot Health on March 12, a consumer-facing healthcare AI platform that aggregates personal health data from over 50 wearable devices — including Apple Watch, Oura, and Fitbit — alongside medical records from more than 50,000 U.S. hospitals and provider organizations through HealthEx.

The platform answers health questions using verified data, identifies patterns across sleep, activity, and vital signs, suggests questions for doctor appointments, and connects users to clinician directories filtered by specialty and insurance. "Fifty million people every day come to Microsoft with health questions," said Dominic King, VP of health at Microsoft AI. "Our belief is that a true health companion needs to do more than general answers."

Copilot Health runs in an isolated environment separate from standard Copilot. Health data is encrypted at rest and in transit and is not used for model training. Microsoft opened a waitlist on March 12 but has not announced a timeline for broader availability.

The consumer-facing approach sets Microsoft apart from Amazon and Salesforce, which both targeted healthcare providers and health systems with their March launches. Where AWS and Salesforce are automating AI clinical workflows for providers, Microsoft is building a medical records AI companion for patients — aggregating and interpreting the information people carry to appointments rather than streamlining what happens inside the exam room. The sector continues to face significant adoption challenges despite the scale of opportunity.
