Glass Health vs Nabla — 2026 Comparison

Plus Clinical Decision Support in 2026?

Glass Health pairs ambient scribing with real-time clinical decision support — differential diagnosis, structured A&P generation, and clinical Q&A backed by clinical guidelines and medical literature — starting free. Nabla is an AI scribe with 20+ EHR integrations and documentation-focused capabilities, but it offers documentation only with no CDS or diagnostic reasoning.

Nabla has built proprietary language models and integrations with 20+ EHR systems including Epic and Oracle — making it one of the more technically developed AI scribes available. Glass Health shares that technical ambition but goes further: ambient scribing paired with real-time clinical insights — including differential diagnosis, suggested history questions, and potential next steps — plus structured assessment and plan generation and clinical Q&A backed by clinical guidelines and medical literature.

Key Takeaways

Nabla has deep EHR integrations (20+ systems including Epic, Oracle Health, and athenahealth) and has been validated by a randomized clinical trial.
Glass Health integrates with Epic, eClinicalWorks, and Athena via SMART on FHIR. Nabla integrates with more EHR systems but does not provide clinical decision support within any of them.
Nabla supports 35+ languages and 55+ specialties. Glass Health currently supports English but provides clinical reasoning tools that Nabla does not offer at any tier.

What Is Nabla?

Nabla is an AI-powered ambient medical scribe founded in 2018 in Paris, France by Alexandre Lebrun, Delphine Groll, and Martin Raison. The engineering team includes members with strong machine learning backgrounds, and Nabla’s AI is built on proprietary language models and speech-to-text — not a GPT wrapper (Hospitalogy, 2025).

As of mid-2025, Nabla reported 85,000+ clinicians across 150+ healthcare organizations, processing 20 million+ patient encounters per year. A randomized clinical trial demonstrated that Nabla users had a decrease in time-in-note compared to control groups.

What Nabla Does

Nabla listens to patient-clinician conversations and generates structured clinical notes in approximately five seconds. Key features include:

Ambient documentation: Real-time transcription and clinical note generation (SOAP format)
Medical coding: Automatic ICD-10 code suggestions with HCC and CPT coding being added
Custom templates: Customizable note templates per specialty and physician writing style
Patient-friendly summaries: Auto-generated plain-language visit summaries
Magic Edit: Post-generation note editing with personalized instructions
Nabla Connect: Plug-and-play module enabling any EHR to embed Nabla’s ambient AI
White-label capability: Powers NextGen Healthcare’s Ambient Assist and Greenway Health integrations
Agentic AI features: Context-Aware Agent, Proactive Coding Agent, and Care Setting Agent that adapts to different clinical environments

What Nabla Does Not Do

Nabla does not generate differential diagnoses, clinical Q&A answers, or clinical reasoning. The Assessment & Plan section requires the clinician to verbally discuss it during the encounter — Nabla transcribes what is said but does not independently generate clinical assessments or treatment plans. CDS and DDx features are on Nabla’s long-term roadmap but will require FDA approval according to company leadership.

How Does Glass Health Compare to Nabla on Features?

Nabla prioritizes documentation speed and EHR coverage. Glass Health matches its scribing capability and adds clinical reasoning on top — real-time clinical insights (differential diagnosis, suggested history questions, and next steps), structured A&P generation, and evidence-based Q&A that Nabla does not attempt.

What Can’t Nabla Do That Glass Health Can?

Nabla’s engineering is real, but the product is scoped to documentation and coding. For clinicians who need diagnostic reasoning alongside their notes, these limitations matter:

Differential diagnosis is not part of the product. Nabla can transcribe a clinician’s spoken differential, but it cannot generate one. It will not suggest diagnoses the clinician has not already mentioned, flag conditions that should be ruled out, or rank possibilities by clinical probability. Glass Health produces a structured DDx automatically during the encounter — organized into Most Likely, Expanded Differential, and Can’t Miss tiers, each with specific diagnostic next steps — and refines it live as new exam findings and test results appear.

The A&P is transcribed, not generated. Nabla captures whatever the clinician says during the assessment and plan portion of the visit and writes it into the note. But it does not independently reason through the clinical data. If a clinician forgets to mention a key consideration, Nabla will not catch it. Glass Health takes the encounter data — history, exam, labs — and builds a complete A&P: problem-based assessments, prioritized diagnostic next steps, treatment recommendations, and citations from medical literature. The AI contributes clinical reasoning, not just a transcript of the clinician’s spoken plan.

No evidence-based Q&A capability. Nabla does not include any mechanism for answering clinical questions, searching medical literature, or citing peer-reviewed sources. If a clinician needs to check a drug interaction or verify a guideline mid-encounter, they must leave Nabla entirely. Glass Health’s built-in clinical Q&A runs agentic searches across clinical guidelines and the broader medical literature, returning cited answers within the same workspace.

Patient history resets every encounter. Nabla does not store patient records, prior labs, imaging, or specialist notes between visits. Each encounter begins without context from the last one. Nabla’s Context-Aware Agent is being developed to incorporate historical patient data, but it is not yet equivalent to persistent longitudinal context. Glass Health maintains a persistent patient record — uploaded documents, imaging, and lab trends carry forward — so that reasoning builds on the patient’s clinical history over time.

Coding nudges are not clinical insights. Nabla’s Proactive Coding Agent suggests ICD-10 codes and documentation integrity improvements, but these are billing optimization cues, not diagnostic guidance. Glass Health provides a fundamentally different kind of real-time input: differential diagnoses that update as the encounter unfolds, history questions the clinician may not have asked, and management considerations relevant to the patient’s presentation.

No extended reasoning for difficult cases. When a patient presents with overlapping multi-system symptoms that resist easy categorization, Glass Health’s Deep Reasoning mode applies sustained analytical depth to produce a more thorough differential and plan. Nabla offers no parallel capability — complex cases receive the same documentation treatment as straightforward ones.

Clinical decision support is years away, not months. Nabla’s leadership has acknowledged that CDS and DDx features sit on the company’s long-term roadmap but will require FDA approval before they can ship. That regulatory timeline means diagnostic reasoning is not an imminent addition — it is a multi-year endeavor that does not help clinicians who need these capabilities today.

Pricing Comparison

	Glass Health	Nabla
Free tier	Lite — $0/month (limited CDS + limited ambient scribing)	Free — $0/month (30 consultations/month; no BAA)
Starter	$20/month ($18/month annual) — extended CDS + ambient scribing	Starter — reportedly ~$119/month (unlimited consultations, EHR integration)
Pro	$90/month ($81/month annual) — unlimited scribing, CDS, all documentation types	Pro — reportedly ~$239/month
Max	$200/month ($180/month annual) — everything + EHR integration (Epic, eCW, Athena)	—
Enterprise	Custom pricing available	Enterprise — custom (SSO, custom ML models, dedicated support)

Contract	Month-to-month or annual	Month-to-month or annual

Glass Health Pro ($90/month) delivers unlimited scribing plus the full CDS suite — three-tier DDx, A&P generation, clinical Q&A, Deep Reasoning, 6 documentation types, custom templates — at a fraction of the cost of Nabla’s reportedly ~$239/month Pro tier, which provides documentation and coding without clinical decision support. Even Nabla’s Starter tier (reportedly ~$119/month) costs more than Glass Health Pro while offering no CDS capabilities.

Nabla’s free tier for interns and residents is a strong academic adoption play. Glass Health’s free Lite tier provides both limited scribing and limited CDS, offering clinical reasoning tools that Nabla doesn’t include at any price.

FAQ

Does Nabla offer clinical decision support?

No. Nabla provides clinical documentation integrity (CDI) nudges for medical coding, but it does not generate differential diagnoses, assessment and plans, treatment suggestions, or clinical reasoning. CDS is on Nabla’s long-term roadmap but will require FDA approval. Glass Health combines ambient scribing with full CDS — real-time clinical insights including differential diagnosis, suggested history questions, and next steps, plus A&P generation, clinical Q&A with citations to clinical guidelines and medical literature, and Deep Reasoning for complex cases.

How does Nabla’s documentation accuracy compare?

Nabla reports high note accuracy — validated by a randomized clinical trial demonstrating a measurable decrease in time-in-note. Both Nabla and Glass Health produce accurate clinical documentation, but Glass Health adds clinical reasoning (DDx, A&P, clinical insights) that Nabla does not offer.

Does Nabla integrate with EHR systems?

Yes. Nabla has 20+ EHR integrations including Epic, Oracle Health, athenahealth, NextGen, Greenway, and Altera, with structured note export directly into EHR fields. Nabla Connect (launched October 2025) enables any EHR to embed Nabla’s ambient AI. Glass Health integrates with Epic, eClinicalWorks, and Athena via SMART on FHIR on the Max plan. Nabla currently has broader EHR coverage.

How many languages does Nabla support?

Nabla supports 35+ languages including English, French, Spanish, Arabic, Mandarin, Hindi, Vietnamese, and many more. Glass Health currently supports English. For multilingual practices, Nabla has a clear advantage on language support.

Is Nabla’s free tier HIPAA compliant?

Nabla’s free tier reportedly does not include a Business Associate Agreement (BAA), which means it may not be suitable for processing protected health information (PHI). The Pro and Enterprise tiers include BAA support. Glass Health’s free Lite tier includes HIPAA compliance with BAA support.

Can Nabla generate differential diagnoses or assessment and plans?

No. Nabla transcribes the clinician’s spoken assessment and plan but does not independently generate clinical reasoning. It does not produce differential diagnoses, evidence-based treatment recommendations, or structured diagnostic reasoning. Glass Health generates structured three-tier DDx, complete A&P with evidence citations, and provides clinical Q&A with agentic search of clinical guidelines and medical literature.

Which is better for large health systems?

Nabla has broader EHR coverage and enterprise deployment capability — white-label capability (NextGen, Greenway), Nabla Connect for custom EHR embedding, and deployments across a range of health systems. Glass Health offers custom enterprise pricing with EHR integration. The choice depends on whether the health system needs documentation only (Nabla) or documentation plus clinical decision support (Glass Health).

Bottom Line

Glass Health vs Nabla comes down to whether you need a documentation-focused scribe or a scribe plus clinical reasoning platform. Nabla is a technically developed AI scribe with proprietary models, 20+ EHR integrations, and a substantial clinician user base. But Nabla is a documentation and coding tool. It does not generate differential diagnoses, assessment and plans, clinical Q&A answers, or real-time diagnostic insights.

At significantly less than Nabla’s reported pricing, Glass Health Pro adds the clinical reasoning layer that Nabla’s roadmap promises but cannot deliver today — structured DDx during encounters, A&P generation with evidence citations, clinical Q&A backed by clinical guidelines and medical literature, and Deep Reasoning for complex cases. Nabla excels at documentation speed. Glass Health adds the diagnostic thinking that comes before the note. Try it free at glass.health/signup.
