We announced the Public Preview of our personal health coach will start rolling-out tomorrow. Our vision is to help empower everyone to live a longer, healthier life with a proactive, personalized and adaptive AI-powered coach.

We’re approaching this work thoughtfully and iteratively, grounded in science and with feedback from the scientific community and you. We continuously validate the coach for safety, helpfulness, accuracy, relevance and personalization, based on data from more than 100,000 hours of human evaluation from generalists and experts in areas like fitness, family medicine, sleep and behavioral science. For more information on how we’re building this, you can dive into our research:
