Microsoft has launched Copilot HealthWithin the Copilot AI assistant, a dedicated, secure space that integrates personal health data from wearables, electronic health records and lab results, then applies AI to uncover what the company calls a “relevant story” about the user’s health.
The product opened its waiting list on March 12, 2026, and is being phased in to English-speaking adults in the United States first.
The launch marks Microsoft’s most direct foray into consumer healthcare AI, placing it alongside its OpenAI ChatGPT Health in January 2026 and Anthropic, which introduced Claude for Health in the same month.
In the words of Dominic King, vice president of Microsoft AI for Healthcare: “2026 feels like an important year for consumer health.”
Microsoft’s consumer AI products Copilot and Bing already ask more than 50 million health-related questions a day, he told attendees at the press briefing.
Copilot Health appears as a dedicated tab in the Copilot web interface and mobile app. Users create a health profile by entering basic details such as age and gender, then optionally combine data sources.
From there, the tool can analyze lab results, interpret wearable readings, surface relationships between data streams, and help users prepare questions before clinical appointments.
Information plumbing
Three connectors power the personal health layer of the platform. Wearable data, including activity levels, sleep patterns and vital signs, comes in from more than 50 devices, including Apple Health, Oura and Fitbit.
Electronic health records are accessed through HealthEx, a US health information infrastructure provider whose network spans more than 52,000 healthcare organizations through direct FHIR endpoint exchange, as well as through TEFCA individual access services at more than 12,000 organizations. Lab results are coordinated through Function, an enterprise-backed medical testing provider.
HealthEx confirmed the partnership in a separate press release issued the same day. The company’s co-founder and CEO Priyanka Agarwal, MD, described the integration as giving users access to their health history. “labs, drugs, conditions, clinical notes and more” with the ability to revoke access at any time.
Microsoft itself has confirmed that users can instantly disconnect any connector and that health data in Copilot Health is not used for AI model training, a point the company has prominently reiterated in all communications around the product.
Unlike personal data, for general health information, Microsoft says it has high content from trusted health organizations in 50 countries, and source selection is validated by a clinical panel using standards set by the National Academy of Medicine.
Answers include citations and source links. The platform also serves up expert-written answer cards from Harvard Health and connects to real-time US provider directories, allowing users to search for clinicians by specialty, location, languages spoken, and insurance coverage.
Artificial intelligence roadmap: towards ‘medical superintelligence’
Microsoft touts Copilot Health as a step toward a longer-term goal it describes as “medical superintelligence.” The company has been using this term since at least the end of 2025. Vision is an artificial intelligence that can combine the breadth of a general practitioner with the depth of a specialist.
The most cited tool for this ambition is the Microsoft AI Diagnostic Orchestrator (MAI-DxO), a research-stage system that the company says has produced strong results in clinical evaluation environments.
Microsoft says that future releases will detail how MAI-DxO can be applied across a wider range of situations and circumstances. The company says any new AI features based on these research capabilities will be released to Copilot Health only after rigorous clinical evaluation and with clear labeling that reads as much as a regulatory buffer as a product design principle.
“We truly believe that we are on the way to medical superintelligence that combines both the broad knowledge of a family physician or general practitioner and the deep field experience of a specialist” said Dominic King, vice president of Microsoft AI for Healthcare.
The question of privacy, governance, and HIPAA
Microsoft has been careful about data management. Copilot Health data and conversations are kept separate from general Copilot interactions, encrypted at rest and in transit, subject to stricter access controls, and not used for model training.
The product has achieved ISO/IEC 42001 certification, the international standard for AI management systems, which requires third-party verification of how an organization builds, manages and improves AI services.
The platform was also developed with an external advisory panel of more than 230 physicians from more than 24 countries, along with consumer advocacy organizations including AARP, which serves 38 million older Americans, and the National Health Council, which represents more than 180 patient advocacy groups.
However, an important regulatory caveat emerged during the press briefings. King confirmed that Copilot Health is not subject to HIPAA, the US federal law governing the privacy and security of patient health information, because it operates as a direct-to-consumer service where users share their information, rather than as a covered healthcare facility.
The king said: “When you’re using your own data, HIPAA isn’t required for a direct-to-consumer experience like this,” In addition to adding that Microsoft intends to announce updates to its HIPAA control systems. He declined to specify what those updates would entail.
This distinction is important. HIPAA compliance forces healthcare organizations to adhere to strict data management, breach notification and minimum necessary use standards.
Consumer health platforms that opt out of HIPAA are not subject to the same enforcement regime as when Copilot Health was launched. The FDA’s easing of rules on wearable clinical decision support in early 2026 adds more regulatory complexity: it means more AI-powered health tools could reach consumers without FDA premarket review.
Clinical admission
Initial expert reaction has been more cautious than hostile. Arjun Manrai, an assistant professor of biomedical informatics at Harvard Medical School, told Healthcare Brew that this approach makes strategic sense, describing the use of personal context in healthcare interactions with artificial intelligence, which will become a defining trend in 2026. Helping people prepare for doctor appointments is a good target for broad language models, he said.
Doctors interviewed by the New York Times acknowledged that AI-powered health tools could help people gain access to health information at a time when care is becoming increasingly expensive and clinicians are increasingly stretched thin.
But the same doctors have raised concerns about the potential for tools like Copilot Health to lead to unnecessary clinical visits, worrying about privacy risks from sharing records with big tech companies and exposing users to potentially clinically irrelevant data samples.
Microsoft’s standard disclaimer is located at the bottom of every Copilot Health communication: the product is not intended to diagnose, treat, or prevent disease and is not a substitute for professional medical advice.
