What is Ada Health?

Ada Health is a medical AI platform that provides symptom assessment and health guidance through a conversational interface informed by one of the largest medical knowledge bases in the world. The app asks targeted questions about your symptoms โ€” their onset, severity, associated factors, and medical history โ€” then uses probabilistic reasoning across thousands of conditions to generate a ranked list of possible causes with confidence percentages. Unlike simple symptom checkers that match keywords to conditions, Ada's AI considers the complex interplay between symptoms, demographics, risk factors, and medical history to provide assessments that peer-reviewed studies have shown match the diagnostic accuracy of general practitioners for common conditions. The platform covers over 12,000 symptoms and conditions across all body systems and age groups, including rare diseases that general practitioners might overlook. Ada is available in 10 languages and has completed over 36 million health assessments globally. The assessment report can be shared with your doctor, providing a structured summary that improves the efficiency of clinical consultations. For healthcare providers, Ada offers an enterprise platform that integrates into telehealth workflows and triage systems, helping organizations route patients to appropriate care levels. The AI is developed with input from over 50 medical specialists and undergoes regular clinical validation studies. Ada takes medical accuracy seriously โ€” it errs on the side of caution, recommending professional consultation for anything beyond clearly benign conditions. While Ada does not diagnose or prescribe treatment, it empowers patients with informed understanding of their symptoms before seeking professional care.
