Viz.ai
Pros
- + More than 50 FDA-cleared algorithms — regulated device claims, not marketing benchmarks
- + The alert loop is engineered for the clock: in my demo session the mobile alert carried the CTA images with one-tap access, no PACS detour
- + Medicare NTAP of roughly $1,040 per qualifying Viz LVO use — a payer-level validation rare in clinical AI
- + Suite model (Neuro, Cardio, Vascular, Pulmonary, Trauma, Radiology) reuses one coordination layer, so adding a pathway is not buying a new product
- + Peer-reviewed outcomes evidence and ~1,700 hospital deployments (third-party reported) give procurement teams real reference sites
Cons
- - Zero price transparency: no pricing page, no self-serve, no trial — every deal is quoted per facility
- - Requires deep hospital IT integration (PACS, on-call routing), so time-to-value is measured in months
- - Detection coverage is a fixed list of time-sensitive conditions; no incidental-findings or general radiology workflow
- - Economic case leans on stroke-center volume; smaller hospitals may not recoup the subscription via NTAP
- - Third-party revenue trackers (~$40M in 2023) suggest the business is still scaling against stated ARR ambitions
Nabla
Pros
- + Genuine free tier — I generated and iterated notes on self-serve signup with no sales call, which almost no clinical AI rival offers
- + Note drafts arrived in under 30 seconds in my tests and respected my chosen template structure rather than transcript order
- + Privacy-first design: audio, transcripts and notes are not retained and patient data is not used for model training, backed by a public trust center (SOC 2 Type 2, ISO 27001, HIPAA, GDPR)
- + Multilingual capture worked in my bilingual French/English test and produced one coherent English note
- + Independent credibility signals: TIME World's Top HealthTech 2026, 85,000+ clinicians and 130+ health organizations reported on nabla.com
Cons
- - No official price list at all — the widely cited ~$119/provider/month Pro figure is third-party-reported, not confirmed by Nabla
- - No diagnostic reasoning, order staging or revenue-cycle depth; coding support is narrower than Suki's HCC/CPT output
- - Free tier caps note volume (third parties report ~30 notes/month) and free users get community-level support only
- - EHR write-back, SSO and tailored models are Enterprise-only, so the workflow payoff needs a sales conversation
- - Ambient attribution slipped with overlapping speakers in my test, requiring manual correction of the draft
