Executive brief
Ambient AI scales when the generated artifact is explicitly a draft and accountable professionals retain edit and signature rights.
AI value · Adoption and encounter coverage
Verified3,442 physicians used the tool in 303,266 encounters; 968 used it in at least 100 encounters.
Adoption does not by itself prove clinical benefit.

Work that left the path
Human role before
Physicians captured and composed encounter documentation.
Human role after
Physicians focus more on the patient, then verify, edit, and sign machine-drafted notes.
AI roleDecision mode: draft generation. Converts encounter audio into a proposed note; it does not diagnose, order, or sign.
