Ada is a clinically grounded symptom assessment app that guides users through a personalized medical interview and suggests appropriate care steps.
Ada combines a medical knowledge base with probabilistic reasoning to deliver symptom assessments that have been validated in clinical studies. Users describe their symptoms in plain language, Ada asks intelligent follow-up questions tailored to their age, history, and risk factors, and the app presents possible explanations with urgency guidance. The company licenses its assessment engine to health systems and insurers, integrating it into digital front doors so patients route to the right level of care before booking. Its content is authored and reviewed by clinicians, and its safety-first design errs toward escalation when uncertainty is high. With assessments completed in dozens of languages, Ada is one of the most widely used AI symptom checkers in the world. Recent product work focuses on care navigation โ not just telling users what might be wrong, but connecting them to telehealth, local providers, or self-care pathways that fit their situation.
The Ada app is free for individuals with optional premium features. Enterprise licensing for health systems and payers is priced by integration and assessment volume through direct agreements.
Individuals seeking trustworthy symptom guidance at any hour, and healthcare organizations that want a clinically validated front door that routes patients to the right care before they consume scarce appointments. It fits populations with variable health literacy, since the interview adapts its language and depth to each person rather than assuming medical vocabulary.
