Microsoft has introduced Copilot Health, a feature within Microsoft Copilot designed to help users organize personal health information and understand medical data. The tool combines health records, wearable device data, and health history into a single interface and uses AI analysis to identify patterns and provide contextual insights.
The launch follows findings from Microsoft’s 2025 Copilot Usage Report, which shows health as the most discussed topic on mobile devices. To better understand how people use AI for health information, Microsoft analyzed more than 500,000 health and wellbeing conversations with Copilot during January 2026.
Copilot Health: Bringing health data together
Copilot Health provides a secure environment where users can consolidate multiple sources of personal health information into one profile. The system integrates data from:
- Activity levels, sleep patterns, vital signs, and other trends from more than 50 wearable devices, including Apple Health, Oura, and Fitbit
- Health records from over 50,000 hospitals and healthcare providers in the United States through HealthEx, including visit summaries, medication lists, and test results
- Comprehensive laboratory results from Function
By analyzing these datasets together, Copilot Health highlights connections between health indicators, such as relationships between sleep patterns, activity levels, and other trends. This allows users to better understand their health data and prepare questions for medical consultations.
Health information sources and care navigation
Microsoft reports that its consumer platforms, including Copilot and Microsoft Bing, respond to more than 50 million health-related questions daily. Copilot relies on information from credible medical organizations across more than 50 countries, verified by Microsoft’s clinical team using principles established by the National Academy of Medicine.
Responses include citations linking to source material and expert-written answer cards developed in collaboration with Harvard Health Publishing. Copilot can also help users locate healthcare providers. In the United States, it connects to real-time provider directories, enabling searches by specialty, location, language, and insurance coverage.
How people use Copilot for health
Microsoft analyzed over 500,000 Copilot conversations during January 2026 using automated analysis of de-identified data. The study identified several usage patterns:
Medical information and symptom interpretation
Health information queries represent the largest category:
- Around 40% of questions relate to symptoms, medical conditions, and treatments
- 10.9% involve interpreting symptoms or understanding lab or imaging results
These conversations often occur when users seek explanations of test results or unexpected symptoms before deciding on further action.
Lifestyle and fitness guidance
About 9% of health questions involve lifestyle support, particularly nutrition and exercise. Many users request personalized guidance rather than general advice.
Healthcare system navigation
Approximately 5.8% of health queries involve navigating healthcare systems, including:
- Finding clinicians based on medical needs and insurance coverage
- Understanding insurance benefits
- Comparing treatment options
- Managing healthcare paperwork
Microsoft says these conversations frequently occur when people are preparing for appointments or managing administrative processes.
Usage patterns by time and device
The study also shows differences in when and how people ask health questions.
Time-of-day trends: Questions about emotional wellbeing increase later in the day:
- Morning/daytime: 3.4% of health queries
- Evening: 4.3%
- Night: 5.2%
Symptom-related questions also rise at night, indicating users often turn to AI when clinicians, pharmacies, or other sources are unavailable.
Mobile vs desktop usage:
- On mobile devices, symptom and condition management questions occur twice as often as on desktop, and emotional wellbeing conversations are 75% more common
- On desktop computers, health research and academic tasks are three times more common, often involving students, researchers, or healthcare professionals
Asking health questions for others
Many users seek health information on behalf of family members. Microsoft found that one in seven conversations about symptoms or condition management are asked for someone else, including children, partners, or older adults. These queries often involve explaining medical terminology, comparing treatments, or summarizing health histories for caregivers managing family healthcare decisions.
AI research and future development
Copilot Health builds on Microsoft’s research in medical AI. The company highlighted Microsoft AI Diagnostic Orchestrator (MAI-DxO), which has shown results in research environments. Microsoft says upcoming publications will describe how these systems could support a broader range of clinical cases.
The long-term goal is AI systems capable of combining general medical knowledge with specialist-level expertise. Microsoft states that new AI features will only be introduced into Copilot Health after clinical evaluation and clear labeling.
Privacy, security, and governance
Copilot Health includes additional privacy protections compared with standard Copilot interactions. Key safeguards include:
- Encryption of health data in transit and at rest
- Strict access controls
- Ability to disconnect wearable or health-record integrations at any time
- Controls to manage or delete stored information
Health conversations are kept separate from general Copilot data, and health data is not used for AI training. Copilot Health has received ISO/IEC 42001 certification, an international standard for AI management systems. It is developed with Microsoft’s internal clinical team and guidance from an external panel of over 230 physicians across 24+ countries.
Partnerships and accessibility
Copilot Health is developed with input from:
- AARP, representing approximately 38 million older Americans
- National Health Council, representing over 180 patient advocacy groups
These collaborations aim to improve accessibility and usability across diverse user groups.
Availability
Copilot Health is launching through a phased rollout. Initially, it is available in English in the United States for adults aged 18 and older. Microsoft has opened a waitlist for early users and plans to expand language support, voice features, and geographic availability.
Microsoft states that Copilot Health is not intended to diagnose, treat, or prevent diseases or other conditions and is not a substitute for professional medical advice.
