Pricing
CustomViz.ai operates exclusively on custom enterprise contracts with hospitals, health systems, and imaging networks. There is no published pricing or self-serve access. Pricing is negotiated based on hospital type, imaging volume, number of conditions covered, and multi-site deployment needs. Viz.ai's Medicare NTAP designation provides hospitals with an additional reimbursement of approximately $1,040 per qualifying patient encounter, partially offsetting platform costs. Contact Viz.ai through viz.ai to schedule a demo and begin enterprise procurement discussions.
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.

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
