What is Ada?
Ada is a free AI-powered symptom assessment app built with doctors. You answer questions about your symptoms, and Ada compares them with thousands of conditions to show possible causes and suggested next steps. It is a CE-marked Class IIa medical device in the EU, holds ISO 27001 and EN ISO 13485 certification, and works in seven languages.
Searching symptoms online often surfaces alarming, unrelated results. Ada instead runs a structured interview, asking follow-up questions the way a clinician would, and returns a ranked list of possible conditions with advice on urgency. It does not replace a diagnosis, but it helps you decide between self-care, a GP appointment or urgent care. You can run assessments for yourself or a family member and share the report with a doctor.
