At CES 2025, artificial intelligence is the buzzword of the moment, especially in the health tech world. Everywhere you turn, there’s an AI algorithm, an AI-powered health recommendation, or an AI chatbot making promises. But AI’s reputation for “hallucinating” or fabricating information has understandably raised concerns—especially when the stakes involve people’s health and privacy.
That’s where Movano’s new chatbot, EvieAI, comes in. Built for the company’s smart ring lineup, this AI assistant aims to set itself apart by being grounded in accuracy and reliability. Movano has made it crystal clear: EvieAI has been post-trained exclusively on peer-reviewed medical journals.
Unlike other generative AI tools like ChatGPT, which pull from massive public datasets riddled with misinformation, EvieAI is specifically tailored for medical use. According to Movano CEO John Mastrototaro, the chatbot draws from over 100,000 accredited medical journals, practices, and procedures vetted by a medical advisory board. These include FDA-approved sources and trusted organizations like the Mayo Clinic, Harvard, and UCLA.
EvieAI’s large language model (LLM) is a “bounded” system, meaning it only references the medical data included in its post-training phase. Whenever a user asks a question, the AI checks for consistency and accuracy by cross-referencing its database. Movano claims this process allows EvieAI to achieve an impressive 99% accuracy rate.
While we couldn’t test EvieAI ourselves at CES, the company’s approach is refreshing. Instead of attempting to answer every question, the AI is programmed to acknowledge when it doesn’t have the information. “If you ask it, ‘What do you think about the election?’, it’s not going to respond,” Mastrototaro explains. “And I think it’s okay to say no if you don’t know the answer to something. We’re only going to give an answer if it’s right.”
EvieAI is positioned as a conversational resource for health and wellness queries, particularly women’s health, aligning with Movano’s focus on products like the Evie Ring. However, it’s designed to guide rather than diagnose. For example, if a user suspects they might have diabetes, EvieAI might ask clarifying questions about symptoms like weight changes or vision issues, but it won’t provide a diagnosis or suggest treatment. In cases of emergencies—like severe injuries or mental health crises—EvieAI will direct users to the ER or provide hotline numbers.
Movano is also keenly aware of the sensitive nature of health information. The company emphasizes that EvieAI adheres to industry-standard encryption for data storage and transmission. Conversations can’t be traced back to individuals, and the chatbot doesn’t collect data for targeted advertising. To further safeguard privacy, chat histories will be periodically deleted.
Movano’s commitment to accuracy and privacy is part of a broader strategy to bring trust to health tech. The company recently secured FDA clearance for its EvieMED ring, a version of its smart ring designed for remote patient monitoring and clinical trials. It has also relaunched the consumer Evie Ring with improvements based on user feedback, such as enhanced sleep tracking and heart rate accuracy.
For now, EvieAI will roll out as a beta version starting January 8th, available to existing Evie Ring users through the Evie app at no extra cost. Movano hopes to eventually integrate individual health data collected by its rings to further personalize the AI assistant.
In a world where health tech often overpromises and underdelivers, Movano’s EvieAI is a bold step forward—one that prioritizes accuracy, privacy, and user trust. By focusing on peer-reviewed medical knowledge and ethical design, EvieAI could redefine what it means to combine AI and health tech.
