OpenAI has made its ChatGPT Health feature available to all users in the United States. This expansion allows users to access and integrate their health and wellness data from various services, including Apple Health, Function, and MyFitnessPal. The feature enables users to manage and track their personal health information in one place. This development is significant as it provides users with a centralized platform to monitor their health and wellness data, potentially leading to better health management and decision-making.
