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.

Summary
The cheapest, fastest text-to-speech API for developers
Ambient AI that turns patient visits into clinical notes, dictation, and coding — right inside the EHR
Unreal Speech Pros & Cons
Pros
- Significantly cheaper per character than ElevenLabs, Amazon Polly, Azure, and Google Cloud TTS
- Very low streaming latency suited for real-time and conversational applications
- Generous free tier that lets developers test the API before committing to a paid plan
- Per-word timestamps make it easy to build synced captions or text-highlighting features
- Simple REST and WebSocket API that is quick to integrate
- Can generate very long audio files quickly, useful for audiobooks and podcasts
Cons
- Voice selection is smaller than some premium competitors and does not include voice cloning
- Some users report confusion around how character overage billing is calculated
- Multilingual voice quality and expressiveness lag behind higher-end providers like ElevenLabs
- No built-in support for importing ebooks or web pages directly, text must be supplied manually
- Free plan requires attribution to Unreal Speech when publishing generated audio
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
