Woebot Health
Pros
- + Peer-reviewed randomised evidence behind the CBT dialogue — the 2017 JMIR RCT is one of the few in this category I consider methodologically serious
- + Between-session CBT exercises were genuinely fast in my use: a full thought record in roughly four minutes through chat
- + Crisis language screening with routing to external resources is built into the conversation layer, not bolted on
- + WB001 postpartum depression program holds FDA Breakthrough Device Designation (granted May 2021) with a double-blind pivotal trial underway since January 2023
- + Shutdown handling was disciplined: stated transcript deadline (July 15, 2025) and explicit data retention posture
Cons
- - The consumer app was retired June 30, 2025 — no new accounts, no individual purchase route at all
- - Pricing is quote-only per member per month or population licence; no published numbers to budget against
- - Scripted dialogue loops back to its CBT framework when conversations go off-script, in my experience within two exchanges
- - No FDA marketing authorisation for WB001; the company concluded in 2025 that pursuing it was not achievable at acceptable cost
- - Not a treatment for severe conditions — adjunctive support for mild to moderate presentations only
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
