Microsoft has introduced Copilot Health, a secure feature within its Copilot AI assistant that compiles personal health data from wearables, electronic health records, and lab results to create a “coherent story” of a user’s health. The waitlist opened on March 12, 2026, with a phased rollout starting in the U.S. for English-speaking adults. This launch positions Microsoft in the consumer health AI sector, joining OpenAI’s ChatGPT Health and Anthropic’s Claude for Healthcare. Dominic King, VP of Health at Microsoft AI, said that 2026 is pivotal for consumer health. Microsoft’s Copilot and Bing handle over 50 million health-related questions daily.
Copilot Health is available as a dedicated tab in the Copilot web interface and app. Users can build a health profile by entering basic information and optionally linking data sources. This tool can analyze lab results, interpret wearable data, identify data connections, and assist users in preparing questions for healthcare appointments.
The platform’s personal health layer leverages three connectors: data from over 50 wearables like Apple Health, Oura, and Fitbit; electronic health records via HealthEx from over 52,000 healthcare organizations; and lab results through Function. HealthEx confirmed this collaboration, emphasizing user access to extensive health histories with revocable access. Microsoft ensures users can instantly disconnect connectors and states health data in Copilot Health is not utilized for AI training.
Microsoft has elevated content from credible health bodies across 50 countries for general health information, with citations and source links in responses. The service also offers expert-written answers from Harvard Health and connects to U.S. provider directories for clinician searches.
Microsoft envisions Copilot Health as a path to “medical superintelligence,” combining the broad insights of a general physician with a specialist’s depth through the Microsoft AI Diagnostic Orchestrator (MAI-DxO). Forthcoming publications will explore MAI-DxO’s broader applicability, emphasizing rigorous evaluation and clear labeling before new AI features release.
Privacy and data governance are priorities for Microsoft. Copilot Health data is stored separately, encrypted, and not used for model training. The product has received ISO/IEC 42001 certification and was developed with input from physicians and consumer advocacy groups.
However, Copilot Health isn’t bound by HIPAA as it’s a direct-to-consumer service where users share their data. King discussed future updates on HIPAA controls. This distinction means the platform is exempt from HIPAA’s strict regulations. The FDA’s relaxed rules on AI health tools add another layer of regulatory complexity.
Initial reactions from experts are cautious. Arjun Manrai from Harvard Medical School called the personal context in AI health interactions a likely 2026 trend, noting its potential to prepare people for clinical visits. Physicians cited the benefits of AI health tools in a costly and stretched healthcare landscape but expressed concerns about privacy, unnecessary visits, and anxiety from data interpretations.
Microsoft’s disclaimer underscores that Copilot Health isn’t for diagnosing, treating, or preventing diseases, and doesn’t replace professional medical advice.
