ICYMI: Microsoft begins phased US rollout of Copilot Health

Microsoft has initiated a phased launch for Copilot Health, a dedicated health-focused space within Copilot that integrates medical records, wearable data, and health history to provide personalized health insights. The initial rollout is limited to adults aged 18 and older in the United States, available in English, and is driven by a waitlist. Microsoft positions this tool for individuals who wish to understand test results, track health patterns over time, and prepare more informed questions for doctor visits, rather than as a tool for diagnosing or treating diseases.

The product emphasizes data aggregation. Microsoft states that Copilot Health can connect to over 50 wearable sources, including Apple Health, Oura, and Fitbit. It can import records from more than 50,000 U.S. hospitals and provider organizations via HealthEx and incorporate lab results from Function. Additionally, it integrates with live U.S. provider directories, allowing users to search for clinicians by specialty, location, language, and insurance. Microsoft assures that responses are based on health organizations from 50 countries, include source citations, and feature expert-written answer cards from Harvard Health. Health conversations are kept separate from the general Copilot; connectors can be revoked at any time, and the company asserts that this data is not used for model training.

The timing of this launch is informed by Microsoft’s own data. The company reports that its consumer products already handle over 50 million health questions daily. A recent analysis of Copilot health usage revealed that approximately 40% of questions pertain to symptoms, conditions, and treatments, while nearly 1 in 5 conversations involve individuals describing their symptoms, interpreting test results, or managing a condition. Microsoft is also linking Copilot Health to a broader research initiative. Its MAI-DxO diagnostic orchestrator, which reportedly achieved up to 85% accuracy on NEJM case proceedings in research settings, is part of the roadmap toward what Microsoft terms “medical superintelligence.” However, any new capabilities will be released only after clinical evaluation and clear labeling.

This launch illustrates how Microsoft is expanding its health AI strategy on two fronts simultaneously. On the clinician side, the company has been promoting Dragon Copilot, developed from Nuance and DAX assets, for clinical documentation and workflow support. On the consumer side, Copilot Health advances Microsoft’s position as a front-end for personal health data. This competition is intensifying rapidly: HealthEx, the same records connector mentioned by Microsoft, announced in January that it had already linked over 50,000 provider organizations to Anthropic’s Claude for personalized health conversations. Microsoft is now establishing its presence in that same domain, with Copilot serving as the consumer interface and its comprehensive healthcare stack supporting it.
