The AI tool is a symptom checker called symptomchecker.io with the name AI Power Medic. It allows users to describe their symptoms in detail, including start time, severity, changes, and relevant factors like health issues and medical history. Users can also list current and recent medication use and relevant medical tests. The tool is not a substitute for professional medical advice or diagnosis and should not be used to make medical decisions. It was created as an experiment to investigate the potential of future AI healthcare.
