Microsoft has introduced Copilot Health, an AI feature within its Copilot app designed to help users understand their medical records and fitness data. The tool aims to provide context for doctor visits without replacing professional medical advice. It integrates data from wearables and health providers to offer personalized insights.
Microsoft announced Copilot Health on March 12, 2026, as a new AI-powered experience in its consumer Copilot app. The tool aggregates medical records, health history, and fitness data from wearables to create a "coherent story" for users, helping them prepare informed questions for healthcare providers. It is housed in a separate, secure space to ensure privacy, with data siloed from general Copilot interactions and protected by encryption at rest and in transit. Users can delete their information or revoke access at any time, and Microsoft states it will not use this data to train its AI models.
Copilot Health draws from over 50 devices, including Apple Watch, Oura, and Fitbit, for activity, fitness, and sleep data. Through HealthEx, it accesses records from more than 50,000 US hospitals and providers, including visit summaries, medications, and test results. It also connects to lab results via Function and real-time US provider directories to match clinicians by location, specialty, language, and insurance.
The feature was developed with input from Microsoft's clinical team and over 230 physicians from dozens of countries, adhering to responsible AI principles. It has earned ISO/IEC 42001 certification for AI management systems. Fine-tuned using the National Academy of Medicine's framework, it incorporates verified information from health organizations in 50 countries and Harvard Health content.
"We are really on the cusp of building a true medical superintelligence," said Mustafa Suleyman, Microsoft AI CEO, emphasizing its potential to learn from personal health data for support and insights. However, Dr. Dominic King, vice president of health at Microsoft AI, clarified: "Copilot Health is not meant to give you a definitive diagnosis or a formal treatment plan, but it's certainly here to support you in getting to the right answers."
Initially available in English for US adults aged 18 and over via a waitlist, it starts free but will move to a subscription model, with pricing undisclosed. This launch follows similar efforts by Amazon, OpenAI, and Anthropic in health AI, amid ongoing concerns about accuracy and data privacy in the sector.
