Pricing
PaidAmazon Rekognition uses pay-as-you-go pricing with no upfront commitment across four usage categories. Image analysis: Group 1 APIs (face search/compare/index) and Group 2 APIs (labels, moderation, text, celebrities) are billed per image on a tiered scale starting at $0.0010 per image for the first million images per month, dropping to $0.0004 per image at higher volumes; Image Properties is billed separately starting at $0.00075 per image. Face metadata storage costs $0.00001 per face or user vector per month. Video analysis: stored video is billed per minute (for example $0.10/min for Label Detection, $0.05/min for Shot Detection), while streaming video events cost around $0.00817 per minute processed. Custom Labels charges $1 per training hour and $4 per inference hour (inference must be manually deprovisioned to stop billing). Face Liveness checks start at $0.015 per check for the first 500,000 checks per month, decreasing at higher volumes. Custom Moderation adds $5 per training hour plus a tiered per-image inference cost starting at $0.0012 per image. New AWS accounts get a 12-month Free Tier (1,000 images/month, 60 video minutes/month, 2 free training hours) plus up to $200 in AWS Free Tier credits.
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.

AWS Rekognition

AWS Rekognition Pros & Cons

Pros

  • Pay-as-you-go pricing with no minimum fees or upfront commitment, and a genuinely useful 12-month free tier
  • No machine learning expertise required to add production-grade computer vision to an application
  • Broad feature set covering faces, labels, text, moderation, and custom object detection in one service
  • Custom Labels can train a usable model from as few as 10 to 20 images via AutoML
  • Deep integration with the AWS ecosystem, including S3, Kinesis Video Streams, and Lambda
  • Scales automatically from small projects to millions of images or hours of video per month

Cons

  • Pricing can scale quickly for high-volume use cases (millions of images or hours of video per month), requiring careful cost modeling
  • Requires an AWS account and familiarity with the AWS console, IAM permissions, and SDKs, which adds setup overhead for non-AWS users
  • Face recognition and identity verification features raise privacy and compliance considerations, especially for biometric data in regulated regions
  • Custom Labels training and inference are billed hourly even when idle unless resources are manually deprovisioned
  • No built-in low-code interface for non-developers — it is API-first and expects a technical integration
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
