Pricing
FreemiumOpenEvidence is free for all verified US healthcare professionals. NPI verification is required to access the platform. The free tier includes full medical AI search, DeepConsult, Visits, Voice Mode, clinical calculators, and the AI-Integrated Doctor Dialer.
Enterprise pricing applies to health system deployments with EHR integration (Epic), multi-subspecialist AI agents, custom knowledge bases, priority compute, advanced visualization, and API licensing for clinical decision support integration into third-party platforms.
Contact OpenEvidence through openevidence.com for enterprise and health system pricing. Note: The platform withdrew from the EU and UK in April 2026 and is currently available to US healthcare professionals only.
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.

Microsoft's enterprise ambient AI for physicians, nurses, and radiologists — formerly Nuance DAX
OpenEvidence Pros & Cons
Pros
- Free for all verified US physicians — no cost barrier for individual clinician adoption
- 757,000+ verified physicians, 40%+ of US doctors use it daily — most widely adopted clinical AI in the US
- $12B valuation (January 2026), $250M Series D — Thrive Capital and DST Global backed
- Answers grounded exclusively in peer-reviewed literature — zero hallucination risk from non-medical sources
- 20M+ clinical consultations per month — proven real-world clinical usage at unprecedented scale
- Epic EHR integration live at Sutter Health — first public health system embedding of clinical AI in EHR
- DeepConsult AI agent handles multi-step clinical reasoning — goes beyond basic search to structured clinical analysis
Cons
- Withdrew from EU and UK in April 2026 — US-only availability limits international use
- Free tier requires verified NPI number — not accessible to non-US clinicians or students without credentials
- Impact on actual clinical decision-making scored only 1.95/4 in one study — physicians still cautious
- DeepConsult and enterprise features require institutional pricing
- Full chart-aware clinical support (reading patient records proactively) not yet available
- Only 20% of physicians fully support AI in clinical decision-making — adoption barriers remain
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
