OpenAI has expanded access to ChatGPT Health, rolling out the feature to all U.S. users. The tool lets people discuss health questions and concerns with ChatGPT, with the ability to pull in personal health data from third-party services including Apple Health, Function, and MyFitnessPal.

The feature works by allowing users to share their health data directly within ChatGPT conversations. This integration means the AI can reference specific metrics like exercise logs, nutrition information, and other wellness data when responding to health-related questions. Users maintain control over what data they share and can revoke access at any time.

OpenAI launched ChatGPT Health as a limited pilot earlier this year. The expansion to all U.S. users represents a significant step in making the tool more widely available, though the rollout remains geographically restricted for now.

The move fits OpenAI's broader strategy of expanding ChatGPT beyond general conversation into specialized domains. Health is a natural application given how many people search for wellness information online. However, OpenAI emphasizes that ChatGPT Health is not a replacement for professional medical advice. The company recommends users consult healthcare providers for diagnosis or treatment decisions.

Integrating health data into ChatGPT raises privacy considerations. OpenAI uses standard data encryption and security practices, though storing health information with an AI service introduces new attack surfaces that users should weigh carefully. The feature also depends on third-party health app integrations, which adds complexity to the data flow.

The ability to cross-reference personal health data with an AI assistant could improve personalized guidance for lifestyle questions, workout planning, and nutrition tracking. At the same time, accuracy remains a concern. ChatGPT sometimes generates confident-sounding but incorrect information, a problem that becomes more serious in health contexts.

This expansion comes as other tech companies push deeper into
