Pricing
PaidVapi offers two plans. Build is usage-based with 60+ free call minutes included, then $0.05 per call minute and $0.005 per SMS/chat message for Vapi hosting (model provider costs for STT, LLM, and TTS are passed through at cost, or $0 if you bring your own API key), 10 call lines included with additional lines at $10/line/month, 14-day call history and 30-day chat history, and community Discord and email support. Scale is an annual contract with a fixed platform fee and committed volume, custom volume-based per-minute pricing, enterprise-grade SSO, RBAC, and SOC 2, data residency options, a support SLA, and a dedicated account team. Both plans offer HIPAA compliance as a $2,000/month add-on and Zero Data Retention as a $1,000/month add-on.
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.

Vapi Pros & Cons

Pros

  • Sub-500ms average latency for natural, real-time voice conversations
  • Proven at massive scale with over 1 billion calls handled for enterprise customers
  • Bring-your-own-API-key option lets teams pay $0 in model provider costs
  • Strong enterprise trust signals including SOC 2, HIPAA, and PCI compliance options
  • Flexible, API-first architecture that fits into any application, hardware, or phone system

Cons

  • Usage-based pricing (calls, model provider costs, add-ons) can be complex to forecast versus a flat monthly fee
  • Enterprise features like SSO, RBAC, and SOC 2 are only included on the custom-priced Scale plan
  • HIPAA compliance ($2K/month) and Zero Data Retention ($1K/month) are costly add-ons rather than included features
  • Being API-first and developer-focused, it requires engineering resources to configure and is not a no-code tool for non-technical teams
  • Call history retention is limited to 14 days on the Build plan unless upgraded
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
