A patient-facing symptom assessment, not a diagnosis
Ada is a symptom-assessment app that interviews a person and suggests possible causes plus a level of urgency. It is a patient-facing product, not a clinician order. Regulatory status and intended use differ by country. An assessment is not a diagnosis, not a prescription, and not a reason to delay emergency care when red-flag symptoms are present.
Clinical setting
People using a phone before they decide whether to seek care, and some health systems that offer the same interview as a front door. A clinician is not in the loop unless the person is handed off.

What was reported
No diagnostic-accuracy figure is copied here. Published evaluations exist and disagree in method; they should be read individually rather than as a single sensitivity.
This is an illustrative composite, not a trial report. At discharge, a model drafts a short explanation of the diagnosis, medicines, and warning signs from the clinician’s own note, in the patient’s language where the hospital supports it. The clinician or pharmacist edits every line before it is printed or sent. The draft is not allowed to add a new instruction that is absent from the signed note. It is not a chatbot the patient can ask for new medical advice.
This is an illustrative composite, not a trial report. A unit feeds monitor alarms through a second layer that withholds repeats already explained by motion, a loose lead, or a value the nurse just acknowledged. The bedside alarm for a new life-threatening rhythm still sounds. The point of the scenario is the governance question: who is allowed to silence what, and how a missed true alarm would be reviewed.
This is an illustrative composite, not a trial report. As the triage nurse types the chief complaint and first vitals, a model suggests an acuity level. The nurse accepts or overrides it, and the accepted level is the one that enters the queue. The scenario is about keeping a human on the decision when under-triage would delay care. No accuracy percentage is claimed, because this entry is not a study.
