Microsoft launches AI platform, Copilot Health

Microsoft is making yet another advance into healthcare AI, launching a new platform called Copilot Health designed to help patients make sense of their health information.

The AI platform gathers data from wearables including Apple Watches and Oura rings, and pulls users’ medical records and lab results into one place, according to the Thursday announcement, leveraging all that data to give users a “coherent” picture of their health.

“Fifty million people every day come to Microsoft with health questions,” Dominic King, VP of health at Microsoft AI, said during a press briefing. “Our belief is that a true health companion needs to do more than general answers. It needs to draw on your health information in context.”

However, not everyone can use Copilot Health just yet. Microsoft opened a waitlist for the platform on March 12, with plans to open access up to the wider public once the company makes sure “everything is working as smoothly and as well as possible.”

King didn’t specify how many people would be able to join the waitlist or how long it would take users on the list to gain access to Copilot Health, though he said it would happen “relatively quickly.”

How it works. In addition to providing personalized health insights, Copilot Health answers users’ questions using data from “credible health organizations across 50 countries,” verified by a team of more than 230 physicians, Microsoft officials said. It includes citations along with the answers so users can see where the information is coming from.

For instance, a patient could ask the platform what patterns it notices in their sleep data or which questions they should ask at an upcoming doctor’s appointment, King said.

Upon launch, Copilot Health will be able to give users insights such as whether their blood pressure is “trending in the wrong direction,” King said. Insights will “get more sophisticated over time,” he added, but did not specify how.

In addition, Copilot Health is connected to clinician directories, allowing users to find a doctor when needed based on specialty and insurance.

In the press release, Microsoft officials said that in order to protect people’s private health information, data included in Copilot Health is kept separate from Copilot and is not used to train any AI models.

“Data in Copilot Health is protected with industry-leading safeguards, including encryption at rest and in transit, strict access controls, and the ability to manage and delete your information when you choose,” the release stated.

The bigger picture. Arjun Manrai, assistant professor of biomedical informatics at Harvard Medical School, told Healthcare Brew this move from Microsoft makes a lot of sense, as Big Tech companies are looking to leverage the context they have on users to personalize services and make chatbots more efficient.

“I think 2026 is the year of context,” he said. “Figuring out how to bring context into your interaction with the [large language model, LLM] is going to be a very important trend and really change how people interact with these chatbots.”

Microsoft’s goal of using Copilot Health to help people prepare for their doctor’s appointments is “a spot-on target for LLMs,” Manrai added, as the technology is always available, whereas a doctor usually isn’t.

However, accuracy is always a concern when it comes to AI, he added.

“These [tools] can be helpful to understand what your doctor told you to prepare you in between visits, but at the end of the day, I’m still going to the doctor,” Manrai said. “You shouldn’t make decisions just based on the advice that’s coming out of these models.”

Not its first rodeo. Microsoft has been making big moves in the healthcare AI space lately.

Earlier this month, the company announced a partnership to integrate its Dragon Copilot AI clinical assistant with professional software provider Wolters Kluwer Health’s clinical decision support tool, UpToDate. Through the partnership, information from Microsoft’s ambient listening tools will be coupled with information from UpToDate, with the goal of giving providers custom recommendations for patient care.

At a February press briefing, Joe Petro, corporate VP of Microsoft health and life sciences solutions and platforms, said that more than 100,000 clinicians have used Dragon Copilot and more than 600 health systems have used the company’s ambient scribe tool, DAX Copilot, in the last 18 months.

Other Big Tech companies including Amazon One Medical, Anthropic, and OpenAI have also launched similar AI tools designed to help patients understand their health data.
