Copilot Health, Microsoft’s new AI assistant for personal health

Microsoft has announced the launch of Copilot Health, a dedicated section within its Copilot assistant designed to consolidate users' health information and provide personalized analysis through artificial intelligence. The service opens a waitlist today for early access in the United States, initially available in English for users aged 18 and over.

The tool integrates data from three main sources: medical records from more than 50,000 US hospitals and healthcare organizations through the HealthEx platform, data from more than 50 wearable devices — including Apple Health, Oura and Fitbit — and laboratory test results from Function. From this data, the system builds a unified health profile that can surface patterns, such as the connection between sleep quality and other wellness indicators.

For general health questions, Microsoft reports that its consumer products already handle more than 50 million health queries a day. Within Copilot Health, responses draw on information from accredited health organizations across 50 countries, verified against criteria established by the National Academy of Medicine, and are supplemented by expert-written answer cards from Harvard Health. The service also includes a doctor search tool that filters by insurance coverage, specialty, location and languages spoken, connected to real-time provider directories.

On the technical side, Microsoft references its MAI-DxO system (Microsoft AI Diagnostic Orchestrator), a research initiative aimed at combining the broad knowledge of a general physician with the depth of a specialist. The company states that any new features drawing on these capabilities will undergo clinical evaluations before being introduced to the product.

On privacy, Copilot Health data is kept separate from the rest of Copilot and encrypted both at rest and in transit. The data is not used for model training. The service has achieved ISO/IEC 42001 certification, the first international standard for AI management systems, and was developed with input from a panel of more than 230 physicians across 24 countries. Microsoft emphasizes that Copilot Health is not intended to replace doctors or to diagnose and treat diseases.
