Where Nuance DAX Copilot Wins
DAX wins on a dimension no competitor has matched: it lives inside Epic. Not alongside it, not connected to it through an API — inside it. When a physician opens a patient chart in Epic’s Haiku or Hyperdrive interface, DAX is already there, capturing the conversation and writing the note directly into the chart without the clinician touching a separate application, browser tab, or mobile device.
This native embedding eliminates the single biggest barrier to ambient scribe adoption: workflow disruption. Clinicians who’ve tried standalone scribes that require opening a separate app, pressing a record button, and then copy-pasting notes into the EHR often abandon the tool within weeks. DAX removes every one of these friction points. The physician’s workflow doesn’t change — they open the chart, see the patient, and find a draft note waiting for review. For health systems where clinician adoption is the primary implementation risk, DAX’s invisible integration is the decisive advantage.
The human QA option is unique among the three platforms. For organisations where documentation accuracy has legal, billing, or compliance implications, DAX offers a layer of human review that catches errors the AI might miss. This doesn’t mean every note is human-reviewed — it means the option exists for high-complexity encounters, new specialties during initial deployment, or quality assurance sampling. Neither Suki nor Nabla offers this hybrid approach.
Enterprise compliance and governance are built into DAX’s architecture, not bolted on. HITRUST CSF certification, SOC 2 Type II compliance, and Microsoft Azure’s healthcare-specific security infrastructure satisfy the institutional procurement requirements that large health systems demand. When a hospital’s CISO, compliance officer, legal counsel, and privacy officer all need to approve an AI tool, DAX’s compliance posture and Microsoft’s enterprise relationship simplify the approval process significantly.
Where DAX falls short: The pricing is the highest in the market ($370–600/provider/month plus $650–700 implementation fees per provider). The 12-month minimum contract eliminates flexibility. Implementation requires significant IT coordination — weeks to months for full deployment. It’s enterprise-only; solo practitioners and small practices are effectively locked out by cost and complexity. And despite its documentation strength, DAX doesn’t offer voice commands for orders, referrals, or prescriptions the way Suki does — it’s a scribe, not an assistant.
Where Suki AI Wins
Suki wins by redefining what an ambient scribe can do. While DAX and Nabla focus on documentation — listening to encounters and generating notes — Suki extends into clinical workflow, functioning as a voice-activated AI assistant that handles documentation as one capability among several.
The voice command interface is the strategic differentiator. A physician using Suki can speak naturally to retrieve a patient’s last haemoglobin result, create an order for imaging, generate a referral letter to a specialist, stage a prescription, and document the encounter — all through voice, all within the same interaction. This goes beyond scribing into genuine workflow automation, eliminating the keyboard and mouse interactions that fragment a clinician’s attention during patient encounters.
EHR compatibility is Suki’s other decisive advantage. With confirmed integrations across Epic, Oracle Health, athenahealth, MEDITECH Expanse, eClinicalWorks, Elation, and additional systems, Suki serves health organisations that DAX and Nabla can’t reach. A regional health system with athenahealth at its primary care clinics and MEDITECH at its hospital can deploy Suki across both environments — a scenario where DAX (Epic-focused) and Nabla (lighter integrations) would leave gaps.
The ICD-10 and HCC coding suggestions generated alongside clinical notes create measurable revenue value. Accurate coding directly impacts reimbursement — a single missed HCC code can cost thousands in risk-adjusted revenue for Medicare Advantage patients. Suki surfaces these coding opportunities as the note is generated, bridging the gap between documentation and revenue cycle in real time.
Multilingual support across 80+ languages makes Suki practical for clinics serving diverse patient populations where encounters occur in multiple languages. DAX’s multilingual capability is more limited, and Nabla currently supports three languages (with more in beta).
Where Suki falls short: Specialty depth varies — KLAS respondents report that performance is strongest in primary care, with some specialties requiring additional tuning. The pricing ($300–400/provider/month) places it in the mid-to-premium range, above Nabla but below DAX. There’s no human QA option for organisations that want documentation accuracy verified by a person. And while EHR integration breadth is the widest, the depth of each individual integration may not match DAX’s Epic-specific embedding.
Where Nabla Wins
Nabla wins on the three factors that matter most for smaller clinical organisations: speed, price, and simplicity.
Sub-20-second note generation is the fastest in the market — a genuinely differentiating metric when you’re seeing 25 patients per day and every minute between encounters matters. DAX takes 2–3 minutes. Suki takes approximately a minute. Nabla delivers a structured note in under 20 seconds. Over a full clinic day, this speed advantage compounds into meaningful time savings.
The pricing structure makes Nabla accessible to practices that DAX and Suki price out. A free tier allows genuine evaluation with real patient encounters (verify BAA availability before using with PHI). Paid plans from approximately $119/provider/month cost a third of Suki and a fifth of DAX. For a four-physician family medicine practice, the annual cost difference is substantial: Nabla at ~$5,700/year versus Suki at ~$16,800/year versus DAX at ~$24,000+/year. The documentation quality needs to justify that price gap — and for many routine primary care and general medicine encounters, it doesn’t.
Deployment simplicity matches the pricing accessibility. Nabla is operational in hours, not weeks. No IT department needed. No enterprise procurement process. A physician can sign up, connect to their EHR (15+ supported systems), configure templates for their specialty, and begin using the tool the same day. For practices without IT support — the reality for most private practices — this self-serve deployment is the difference between adopting AI now and waiting indefinitely.
Customisable templates across specialties allow clinicians to configure note output formats that match their documentation preferences, institutional requirements, and specialty-specific structures. The emerging agentic features (pre-charting, medical codification, patient summary generation) signal Nabla’s evolution beyond pure documentation toward broader clinical workflow support.
Where Nabla falls short: The free tier may not include a BAA — critical for HIPAA compliance with real patient data. EHR write-back varies by integration; some EHR connections require copy-paste rather than direct note insertion. Nabla is less established in large US health systems than DAX or Abridge, making institutional procurement harder. The compliance certifications, while solid, don’t include HITRUST CSF (which some enterprise procurement teams require). And the multilingual support (three languages plus beta) is far behind Suki’s 80+.
Pricing Comparison
| Nuance DAX | Suki AI | Nabla | |
|---|---|---|---|
| Solo provider (monthly) | Not available | ~$300–400 | Free–$119 |
| 5-provider practice (monthly) | ~$1,850–3,000 + implementation | ~$1,500–2,000 | ~$595 (or free tier) |
| 20-provider group (monthly) | ~$7,400–12,000 | ~$6,000–8,000 | ~$2,380 (or enterprise custom) |
| 100-provider system (monthly) | Custom (volume discounts) | Custom | Custom |
| Implementation fees | $650–700/provider | Minimal | None |
| Contract minimum | 12 months | Flexible | Monthly available |
| Free trial/tier | Demo/pilot only | Trial available | Free tier |
| Annual savings | ~20% on annual billing | Negotiable | ~20% |
The pricing gap is dramatic at small scale and narrows at enterprise scale. For a solo provider, Nabla’s free tier versus DAX’s “not available” makes the comparison moot. For a 5-provider practice, Nabla costs $595/month versus Suki at $1,500–2,000 and DAX at $1,850–3,000 — before DAX’s implementation fees. At 100+ providers, enterprise negotiations bring all three platforms into more comparable territory, and the decision shifts from price to integration depth and institutional requirements.

Frequently Asked Questions
Can I switch between these platforms if my first choice doesn’t work out?
Yes — ambient scribes don’t create deep lock-in. Your clinical notes live in your EHR, not in the scribe platform. Switching means installing a new tool and adjusting to a different note style, but your data stays in your EHR. The transition takes 1–2 weeks of parallel use to verify note quality with the new tool. The exception: if you’ve customised extensive specialty templates in Nabla, you’ll need to rebuild those templates on the new platform.
Will Epic’s native AI scribe make DAX obsolete?
Epic announced a native AI scribe (leveraging Microsoft’s Dragon AI) for wider release in 2026. Since DAX is already built on Dragon/Microsoft technology, the native Epic scribe is essentially DAX embedded even more deeply. For existing DAX customers, the transition should be seamless. For health systems that haven’t yet deployed an ambient scribe, the native Epic option may offer a simpler procurement path. However, Epic’s native tool may initially lag behind DAX, Suki, and Nabla in specialty breadth and feature depth — a common pattern when EHR vendors build capabilities that specialist AI companies have refined over years.
Which scribe is most accurate for specialty encounters?
No single platform dominates across all specialties. DAX is strongest in high-volume specialties with established deployment patterns at major health systems. Suki reports the strongest primary care performance with specialty depth that varies by site. Nabla’s customisable templates allow specialty-specific configuration but require clinician investment in template design. For complex specialties (oncology, cardiology, psychiatry), dedicated platforms like DeepScribe and Ambience Healthcare may outperform all three general-purpose ambient scribes. Always trial with 20–30 real encounters in your specific specialty before committing.
