AI ambient scribe and clinical AI partner for clinicians
Listens to the consultation in real time and converts it into a structured clinical note, with an emphasis on accurate drug names and specialty terminology.
Reviews the edits a clinician makes, groups recurring corrections, and proposes word library entries, auto-edit rules, and template changes to approve.
Writes referral letters, letters back to the GP, care plans, and patient recaps straight from the finished note.
Builds the day's list, stages meds, allergies and recent results per patient, and drafts ISBAR-style shift handovers.
