Microsoft has introduced Copilot Health, a new AI-powered health companion designed to help people interpret their personal health information and prepare more effectively for conversations with healthcare professionals. The service, currently rolling out in phases in the United States, aims to combine health records, wearable data and medical information into a single digital environment that generates personalized insights.
According to Microsoft, the new feature creates a dedicated and secure space within its Copilot ecosystem where users can organize health-related data and receive contextual explanations about their health status. The company emphasizes that the system is intended to support patients rather than replace medical professionals. With the introduction of Copilot Health, Microsoft follows in the footsteps of counterparts Open AI with ChatGPT Health and Anthropic with Claude for Helathcare, both introduced in the first weeks of this year.
From fragmented data to personal insights
Many people already collect large amounts of health-related data through wearables, lab tests and electronic health records. However, interpreting these data and connecting them to symptoms or lifestyle factors remains challenging.
Copilot Health is designed to aggregate information from multiple sources, including activity trackers, sleep data and vital signs from more than 50 wearable platforms such as Apple Health, Oura and Fitbit. The system can also connect to health records from more than 50,000 hospitals and healthcare providers in the United States through the HealthEx network, allowing users to view visit summaries, medication lists and diagnostic results in one place.
Using AI, the platform analyzes patterns in these datasets to generate explanations and suggestions that could help users better understand their health. For example, it may highlight links between sleep patterns, activity levels and other measurable indicators.
Access to trusted medical information
Microsoft says Copilot Health also aims to improve access to reliable health information. The company reports that its consumer platforms already answer more than 50 million health-related questions every day.
To increase the reliability of responses, the system prioritizes information from recognized health organizations across more than 50 countries. These sources are reviewed by Microsoft’s clinical team using evaluation principles derived from the National Academy of Medicine. Responses include citations and links to original sources, as well as expert-written explanations from Harvard Health.
In addition, the platform integrates with real-time US healthcare provider directories, enabling users to search for clinicians by specialty, location, language and insurance coverage.
AI-driven health analysis
Copilot Health builds on several ongoing AI initiatives within Microsoft’s health research activities. One example is the Microsoft AI Diagnostic Orchestrator (MAI-DxO), a system designed to analyze clinical information and support diagnostic reasoning. While still primarily evaluated in research environments, such technologies could eventually contribute to more advanced health analysis capabilities within the platform.
Microsoft describes this development as part of a broader ambition to provide access to highly advanced medical AI systems capable of combining broad general medical knowledge with specialized expertise. The company states that any new AI features will only be introduced after clinical evaluation and will be clearly labeled.
Privacy and security
Because Copilot Health processes sensitive medical information, Microsoft has implemented additional privacy and security measures. Health-related conversations and data are separated from the general Copilot environment and protected with encryption, strict access controls and user-managed data settings.
Users can disconnect linked data sources, such as electronic health records or wearable devices, at any time. Microsoft also states that personal data within Copilot Health will not be used to train AI models.
The platform has been developed in collaboration with an internal clinical team and with input from an international advisory group of more than 230 physicians from 24 countries. Microsoft says the system follows its responsible AI principles focused on transparency, fairness and accountability.
Copilot Health has also obtained ISO/IEC 42001 certification, a recently introduced international standard for AI management systems.
Initial rollout in the United States
Microsoft is launching Copilot Health initially in English in the United States for adults aged 18 and older. The company has opened a waitlist for early users and plans to expand language support and geographic availability in the future.
Microsoft stresses that Copilot Health is not intended to diagnose, treat or prevent medical conditions and should not replace professional medical advice. Instead, the platform is designed to help people better understand their health information and prepare more informed discussions with healthcare providers.
