What is Microsoft Nuance DAX?
Microsoft Nuance DAX is the most widely deployed ambient clinical documentation solution, used by 550+ health systems. Microsoft acquired Nuance in 2021. DAX activates at the start of a patient encounter, listens to the natural conversation, and generates a structured clinical note automatically — without dictation or manual entry.
DAX Copilot extends beyond documentation to include ChatGPT-powered patient message drafting, prior authorisation support, and clinical AI workflow assistance. Customers report 50-70% reduction in post-visit documentation time, directly addressing physician burnout driven by documentation burden.
Deep Epic integration — covering 30%+ of US hospitals — and decades of clinical voice AI history differentiate DAX from newer entrants like Nabla and Suki.
How Microsoft Nuance DAX works
Microsoft Nuance DAX runs as speech-to-text software built around audio and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios, and android.
