AI for patient

Cases of patients who used AI to understand test results, organize symptoms, prepare questions for appointments and follow treatments. Clinical decisions remain with the health professional.

Each case includes the original account with a link to the source, what worked, what went wrong and a prompt we wrote for you to adapt to your own situation. Replace what is in brackets with your own details and review the result before using it.

12 cases, 3 of them from Brazil, from newest to oldest. The tools that show up most in these accounts are ChatGPT, Claude, and Grok Bot. The most common topics are health. Every case is checked by hand before it enters the directory.
