AI symptom checkers are digital tools that use artificial intelligence to assist patients in understanding potential causes of their symptoms and determining appropriate care pathways. These tools typically rely on natural language processing and machine learning to analyze user-provided information, such as symptoms, medical history, and demographics, against extensive medical databases. By providing personalized recommendations, AI symptom checkers can guide users toward self-care, telehealth consultations, or in-person visits based on the urgency and complexity of their symptoms. They are often integrated into broader healthcare systems, including patient portals and telehealth platforms, to enable seamless transitions from symptom assessment to care delivery.
