A chatbot symptom checker developed in Israel performs better than seven rival products, according to an independent study. Symptom checkers use AI to simulate a conversation with a doctor, and provide a more accurate diagnosis than Googling a series of symptoms. However, physicians are skeptical to trust them, as they were designed to be used by patients rather than by doctors making diagnoses. A new study published in the International Journal of Medical Informatics (IJMI) found that Israeli-based Kahun gathered the best and most relevant insights. The researchers assessed the data-gathering capabilities of eight chatbot symptom checkers – K Health, Babylon, ADA, Buoy, Kahun, Mediktor, Symptomae, and Your.MD.
