From Tokyo: Microsoft has joined the rush to put artificial intelligence at the centre of consumer healthcare, unveiling Copilot Health, a tool designed to help patients make sense of fragmented medical records and wearable fitness data. The company released the product on Thursday, opening a waitlist for access in the United States.
The tool represents an intriguing bet on AI's potential to bridge a genuine gap in healthcare. There is a growing mismatch between demand for healthcare and its constrained supply, with shortages of clinicians and long wait times for medical appointments. By consolidating scattered health information, Microsoft hopes patients will arrive at appointments better informed and ask more useful questions.
Copilot Health brings together health records, wearable data, and health history into one place, then applies intelligence to turn them into a coherent story. The tool can pull data from wearable devices such as an Oura ring or Fitbit, as well as health records from more than 50,000 US hospitals and provider organisations through a platform called HealthEx. It also accesses lab results and can help users find nearby clinicians based on location, specialty and insurance coverage.
Microsoft's timing reveals something important about where Silicon Valley sees the market heading. Users ask more than 50 million health-related questions every day across AI-powered consumer products like Copilot and Bing. In an analysis of more than 500,000 de-identified Copilot conversations from January 2026, Microsoft found that nearly one in five involved personal symptom assessment or condition discussion. People are already turning to AI for health answers; the companies building these tools simply want to be the ones providing that service.
Yet Microsoft is hardly alone in this space. Two months ago, OpenAI rolled out ChatGPT Health, a feature that connects its artificial intelligence chatbot with users' medical records and wellness apps. Amazon expanded its Health AI tool beyond One Medical, making it available on the Amazon website and app, with Prime members in the US having the option to chat about certain conditions with a One Medical provider via direct message at no extra cost.
Microsoft emphasises its approach carries extra safeguards. Copilot Health conversations and data are isolated from general Copilot and kept under additional access, privacy, and safety controls, with data protected by encryption at rest and in transit, strict access controls, and the ability to manage and delete information. The company also notes it will not use health data to train its underlying AI models, matching a commitment OpenAI made with ChatGPT Health.
The clinical credentials matter here. Copilot Health is developed with Microsoft's internal clinical team and informed by an external panel of more than 230 physicians from more than 24 countries, who contribute medical expertise, safety feedback, and real-world perspective. The tool has obtained ISO/IEC 42001 certification, an independent standard for AI management systems.
Yet even as companies build in safeguards, real risks persist. Research published recently found ChatGPT Health often underestimated the severity of serious cases, like recommending a patient going into respiratory failure see a doctor within 24 to 48 hours instead of going to the emergency room. AI systems can hallucinate, providing confident-sounding advice that is medically wrong. Distinguishing between a reassuring symptom checker and a tool that might delay necessary emergency care is not academic.
Microsoft's response to these concerns is straightforward: the tool is designed to support doctor visits, not replace them. Copilot Health does not replace a doctor but makes every minute with them count more. Still, once a patient has a coherent, AI-generated narrative of their health history, the temptation to defer medical consultation may prove strong.
While users will be able to try Copilot Health for free at first, Microsoft plans to charge for access via a subscription, though the company has not yet disclosed pricing details. For now, the company is taking a careful approach, opening access through a phased rollout with a waitlist. The tool is currently available in English for adults in the United States, with expanded language support and additional geographies to follow.
What emerges is a genuine tension: Given how tough it is for many people to access affordable healthcare and the fact their data and health records are often spread across a number of providers, there are perceived benefits of using such tools from AI companies. Yet trusting a chatbot with your complete medical history, even a carefully built one, requires a comfort with AI-assisted medicine that many patients, and many regulators, have not yet developed. Microsoft's Copilot Health will succeed or fail not on its technology alone, but on whether people trust the company more than they fear AI getting healthcare decisions wrong.
