Quick answer

DAX Copilot from Nuance (Microsoft) is a market-leading ambient scribe, deeply integrated with Epic and enterprise EHRs. It targets health systems and larger groups but is increasingly available for independent practices. Pricing is per-provider-per-month; expect enterprise-style procurement.

Editorial verdict

Nuance DAX is a defensible default in Epic and Microsoft-aligned environments. Independent practices willing to run enterprise procurement can get real value. If you're a small practice without an IT team, Abridge, Suki, or Freed will typically deliver faster and at more predictable pricing.
