Pricing
CustomMicrosoft does not publish self-serve pricing for DAX Copilot / Dragon Copilot; access is sold through Microsoft sales or authorized Cloud Solution Provider resellers, and pricing has varied significantly by channel and date. For years, authorized resellers commonly quoted $369-$830+ per provider per month plus a one-time setup fee (often around $650-$700), depending on contract size and minimum term. In a May 2026 marketplace restructuring, Microsoft published tiered list pricing including a Flex plan at roughly $604.80 per user per month (base license plus pay-as-you-go ambient use) and a higher uncapped Per-User tier around $1,512 per user per month (itself a 57% cut from a prior list price). A lower-cost "Physician Practice" license aimed at 5-50 clinician offices was briefly offered via the CSP channel at roughly $150-$160 per user per month before reaching end-of-sale on May 1, 2026. Large health systems negotiating volume, multi-year contracts frequently report effective rates well below these list prices. There is no public free trial for individual purchase, though Microsoft runs structured 30-90 day enterprise pilot programs for qualifying health systems.

Summary
Microsoft's enterprise ambient AI for physicians, nurses, and radiologists — formerly Nuance DAX
Your AI-powered academic co-pilot for essays, math, research & more.
DAX Copilot Pros & Cons
Pros
- Broadest role coverage of any major ambient AI platform, spanning physicians, nurses, and radiologists in one product family
- Deepest, longest-running Epic integration in the category, built on two decades of Dragon speech technology
- Backed by Microsoft's security, compliance (HITRUST, SOC 2 Type II), and Azure infrastructure at massive scale
- Extensible via a Developer Kit and third-party app marketplace rather than a closed, single-vendor tool
- Strong, publicly documented customer outcomes (time-in-note reductions, added appointments) across large health systems
- Available across multiple countries for physicians, with continued regional expansion
Cons
- No public pricing; buyers must go through Microsoft sales or a reseller, and quoted rates vary enormously (roughly $150 to $1,500+ per provider per month across sources)
- No self-serve signup or public free trial, unlike most consumer-facing AI scribes; enterprise procurement is required even for small practices
- Historically the most expensive mainstream ambient scribe, which prices out solo clinicians and small independent practices
- EHR write-back connectors for non-Epic systems are sometimes a separate, additional cost arranged through third-party partners
- Nurse and radiologist experiences have more limited geographic availability (US-only, with radiology still in preview) than the physician product
