Anyone wanting a structured first look at symptoms gets a free assessment, and it is not a diagnosis.
Kenning's take
What it does
Ada is a symptom checker app. The user answers simple questions about their health and symptoms, and Ada's AI compares the answers with its medical knowledge of thousands of conditions to produce a report of possible causes and suggested next steps, such as where to seek care.
- 24/7 symptom assessment by question and answer
- report of possible causes and next steps
- checks for the user or a relative
- doctor-written medical library on ada.com
Who it suits. Suits people who want a structured first look at their symptoms before deciding whether to see a GP, not a diagnosis.
