At the 2025 Consumer Electronics Show (CES), Artificial Intelligence (AI) emerged as a key focus in health technology. AI algorithms, health recommendations powered by AI, and AI chatbots were ubiquitous. However, due to frequent misinformation generated by AI, especially in the healthcare sector where precision and privacy protection are paramount, it has become a contentious topic.
Movano, a smart ring manufacturer, has set strict boundaries for its new chatbot EvieAI: it is trained exclusively on peer-reviewed medical journals during its post-training phase.
EvieAI aims to be a more accurate alternative to ChatGPT. Unlike ChatGPT and other similar generative AI assistants, EvieAI theoretically does not draw information from public databases riddled with inaccuracies regarding health and wellness. According to John Mastrototaro, CEO of Movano, EvieAI is trained solely on materials authored by over 100,000 medical professionals and remains confined to this scope.
All data accessed by EvieAI comes from authoritative sources approved by a medical advisory board, including FDA-approved journals, practices, and procedures. As a constrained Large Language Model (LLM), EvieAI references only the medical data it was exposed to during its "post-training" phase after initial creation. This data is cross-verified with organizations such as Mayo Clinic, Harvard University, and UCLA before providing responses.
Movano claims that EvieAI achieves an accuracy rate of up to 99%, though verification prior to CES was not possible. The company attributes this high accuracy to the LLM's continuous verification of the consistency and accuracy of information provided in conversations against its training data.
Achieving such a high level of accuracy is both a formidable challenge and a bold claim. Most chatbots struggle to provide reliable statements, with some deliberately avoiding the health and medical domains due to the high risks involved. Nonetheless, when questioned about AI-generated misinformation, Mastrototaro stated that Movano is not concerned about EvieAI admitting it doesn't know the answer.
EvieAI is designed to serve as a conversational resource for health and wellness queries, particularly focusing on women's health (similar to the company's Evie Ring). However, health, wellness, and medicine are ever-evolving fields. Even peer-reviewed studies can yield conflicting results, and doctors may have differing views on emerging science. Moreover, health tech typically avoids offering content that could be construed as diagnostic or medical advice, given the regulatory requirements of the FDA.
To address this, Mastrototaro mentioned that the LLM will undergo monthly updates, incorporating newly approved documents such as medical journal articles and reports on breakthroughs. He also emphasized that EvieAI will refrain from any diagnostic content. Instead of proposing treatment plans, EvieAI acts as a guide by asking clarifying questions to direct users. For example, if a user suspects diabetes, it might inquire about symptoms like vision changes or weight fluctuations, along with dietary habits. If a user indicates severe conditions like severed fingers or suicidal thoughts, it directs them to emergency services or provides appropriate helpline numbers. EvieAI aims to assist users in researching and preparing for medical consultations in a more natural and supportive manner, steering clear of the information overload found on sites like WebMD.
In terms of privacy, Movano assures that EvieAI will adhere to industry-standard encryption protocols for storage and transmission, ensuring no chat can be traced back to an individual. Mastrototaro further noted that conversation data will be periodically deleted and not used for targeted advertising.
While commitments to privacy and accuracy in health tech can easily be dismissed, Movano has consistently upheld the best practices and standards of the medical industry. The company recently obtained FDA approval for its EvieMED ring, intended for remote patient monitoring and clinical trials. Additionally, Movano has relaunched the consumer version of the Evie Ring to better address initial customer feedback, such as improving sleep and heart rate monitoring accuracy.
Looking ahead, Movano plans to integrate personal health data collected by its smart rings. For now, the beta version of EvieAI will be available free within the Evie app starting January 8th for existing Evie Ring users.
