# Ada Health

> Ada is an AI symptom assessment app used by 15 million people globally. Answer questions about your symptoms and Ada provides a personalized assessment of potential causes and recommended next steps.

Ada Health is one of the world's most clinically validated AI health assessment tools. Through a conversational interface, Ada asks questions about a user's symptoms — their location, character, duration, severity, and associated factors — and produces a personalized assessment of potential medical conditions, ranked by probability and seriousness. Ada's assessments are built on a medical knowledge base developed with physicians and continuously updated with clinical evidence. Over 15 million people in 130+ countries have used Ada, and its clinical accuracy has been independently validated against physician assessments in peer-reviewed research. The app also provides a personal health log where users can track symptoms, medications, and conditions over time — generating a health timeline they can share with doctors to provide better context in consultations. For healthcare providers, Ada's B2B platform (Ada for Health Systems) integrates symptom triage into patient portals, enabling patients to complete a guided symptom assessment before appointments. This triage data arrives in the clinical record before the patient enters the room, improving consultation efficiency. Ada operates under strict data privacy standards with ISO 27001 certification and GDPR compliance. It is registered as a medical device in the EU (Class IIa Medical Device) and has received regulatory recognition in multiple markets — a rare achievement for consumer health apps.
