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.
FreemiumNabla does not publish exact pricing on its official website; the primary calls-to-action are a free trial (via app.nabla.com) and "Talk to our team" for enterprise sales. Third-party sources consistently report a free tier with usage limits, with paid individual/clinician plans starting around $119/month per provider and higher tiers reported near $239/month per provider. Larger health-system deployments — Nabla's core market, spanning 130+ organizations — are sold via custom enterprise contracts with volume-based pricing, with independent estimates placing typical enterprise rates in the $150-$400/month per provider range depending on scale, EHR integration depth, and features. Exact costs require a sales conversation with Nabla.

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
Nabla Pros & Cons
Pros
- Fast note generation, roughly five seconds, that closely mirrors real clinical documentation in independent tests
- Deep native integration with Epic and other major EHRs rather than copy-paste workflows
- Broad specialty and language coverage suited to large, diverse health systems
- Strong compliance posture (HIPAA, SOC 2 Type 2, ISO 27001, GDPR) with configurable data retention
- Backed by peer-reviewed evidence, including a NEJM AI randomized trial showing documentation-time reductions
- Combines documentation, dictation, and coding in one platform instead of separate point tools
Cons
- Pricing isn't published; individuals and smaller practices must go through a sales conversation or rely on third-party estimates to budget
- Primarily built for hospitals and health systems, so solo clinicians and small practices may find it less tailored than SMB-focused scribes
- Relies on ambient recording, so encounters where a patient or clinician can't or won't be recorded aren't well supported
- Some independent reviews note limited customization and quality drop-off on complex, multi-problem visits
- Mobile app store ratings are mixed and based on a relatively small number of reviews compared to the platform's overall clinician base
