## Summary

People report growing trepidation about artificial intelligence in many fields, but health care shows some optimism. AI tools built on large language models, such as the chatbot ChatGPT, are widely used for health advice. It is estimated that one‑third of US adults turn to chatbots for answers to health questions, and it has been suggested that about 230 million people ask ChatGPT health and wellness questions every week.

Writing in Nature, Heydari et al. present their response to this demand by creating and assessing an AI personal health ‘agent’. The agent is designed to analyse an individual’s health data and offer personalised advice, illustrating a prototype for future AI‑driven health support.
