Ada Health

What is Ada Health?

Ada Health is a symptom assessment application developed by Ada Health GmbH, headquartered in Berlin, Germany. Founded in 2011, Ada uses clinical artificial intelligence to conduct a structured conversation with the user about their symptoms, medical history, age, and gender, generating a ranked list of possible associated conditions.

The system was developed based on a vast database of medical knowledge and has been used by more than 11 million people worldwide. Unlike generic internet searches for symptoms, Ada asks questions in a logical sequence — similar to medical triage — to narrow down diagnostic hypotheses with greater accuracy.

In addition to the consumer version (which is free), Ada offers B2B solutions for hospitals, insurers, and healthcare systems, integrating its clinical AI as a triage tool into existing healthcare workflows.

How it works

The user starts an assessment by describing the main symptom. Ada then asks additional questions about location, intensity, duration, factors that make it better or worse, and relevant health history. Based on the answers, the system generates a report with the most likely conditions, ordered by relevance, and indicates the urgency level of care — ranging from self-care to an immediate visit to an emergency room.

The report can be saved and shared with a doctor, functioning as a structured summary of the patient's complaint before the consultation.
