This clever ring deploys an AI chatbot trained in medical journals

Artificial intelligence is the buzzword in the health technology industry at CES 2025. Everywhere you look, you will find AI algorithms, AI health recommendations, and AI chatbots. The thing is, AI has a reputation for figuring things out, and when it comes to health, the stakes for accuracy and privacy are high.

That’s why the clever ring maker Movano wants to make one thing clear his fresh chatbot, EvieAI: This one was trained exclusively in peer-reviewed medical journals.

EvieAI is designed to be a more right alternative to something like ChatGPT. The difference is that unlike ChatGPT and other similar generative AI assistants, EvieAI will theoretically not tap into the immense repositories of public data where misinformation about health and wellness is rampant. According to Movano CEO John Mastrototaro, it was trained on more than 100,000 medical journals written by physicians.

All data the LLM has access to comes from accredited sources referenced by the medical advisory board, Mastrototaro says. This includes FDA-approved journals, practices, and procedures. EvieAI is a constrained LLM solution, which means it will only operate data from the “post-training” phase after it is initially created. In this case, it is about medical data. The data is then compared to organizations such as Mayo Clinic, Harvard and UCLA. LLM does this by referencing this external data before responding and ensuring there is no conflict.

According to Movano, the score is 99 percent, although we weren’t able to test EvieAI ourselves before CES. The company says this is possible because every time you send a request to EvieAI, LLM tracks whether the information provided in the interview is consistent and right compared to the data it was trained on.

Achieving this level of accuracy is a high order and a bold claim. Most chatbots do not make reliably right claims, and some specifically avoid health and medicine precisely because the stakes are so high. However, when I ask about the AI’s tendency to hallucinate, I am firmly told that Movano is not afraid of EvieAI telling users it doesn’t have the answer.

“If you ask, ‘What do you think about the elections?’, he won’t answer,” Mastrototaro says. “He won’t tell you because he doesn’t have any information about it.”

“I think it’s okay to say no if you don’t know the answer to a question,” he adds. “And I think sometimes, using other tools available, they will respond one way or another, whether it’s good or bad. We will simply give an answer only if it is correct.”

EvieAI aims to be a conversational resource that provides clear and concise answers to questions about health and wellness, with a focus on women’s health (similar to the company’s Evie Ring).

Yet health, wellness and medicine are constantly changing. Even peer-reviewed studies may present conflicting conclusions. Doctors don’t always agree on emerging science. Generally speaking, health tech also avoids anything that could be considered diagnostic or medical advice – something that would require FDA oversight.

To this end, Mastrototaro says the LLM is updated monthly with fresh approved documents such as medical journals and articles detailing breakthroughs. It also emphasizes that EvieAI avoids any diagnostic activities. The AI ​​will not be treated, but will act more as a guide that asks clarifying questions to guide you in the right direction. For example, if you think you may have diabetes, they may ask questions to clarify whether you have experienced vision loss or weight gain, and may also ask about your diet. However, if you tell him that you have cut off your finger or express that you are having suicidal thoughts, he will refer you to the emergency department or a number to call the appropriate helpline. We hope EvieAI will aid people better research and prepare for a doctor’s visit in a more natural and supportive way than, say, falling down the WebMD rabbit hole.

In terms of privacy, Movano says EvieAI will follow industry-standard encryption during storage and transmission, and that no conversations will be traceable to specific individuals. Mastrototaro also says that call data will be deleted periodically and will not be used for targeted advertising.

It’s basic to roll your eyes when you hear promises of privacy and accuracy in health technology. To date, Movano has demonstrated an unwavering commitment to healthcare industry best practices and standards. Recently gained FDA Clearance for EvieMED Ringa corporate version of the ring designed for remote patient monitoring and clinical trials. Movano too recently reissued a consumer version of the Evie Ring that better incorporates initial customer feedback such as improved sleep and heart rate accuracy.

In the future, Movano hopes to continue to incorporate individual health data collected by clever rings. For now, however, the beta version will be made available to existing Evie Ring users from January 8 at no additional cost.
