ada.comAbout Ada Health
Ada Health is an AI-powered symptom checker and health assessment platform used by over 12 million people and deployed by healthcare systems in 140+ countries. Ada's AI asks about your symptoms the way a doctor would — systematically, following up on responses with relevant clarifying questions — then generates a prioritized differential diagnosis with probability-weighted possible conditions. Ada is medically certified as a Class I medical device in the EU and FDA-registered in the US. Unlike consumer symptom checkers that rely on decision trees, Ada uses a Bayesian network with over 10,000 conditions. It's used by Bupa, Vifor Pharma, and NHS in clinical deployments.
