If documentation is eating your evenings, you have probably evaluated Nabla — a widely adopted ambient AI assistant known for easing clinician burnout, setting up quickly, and supporting a broad range of languages. You may also be weighing LucasAI, a US-focused ambient clinical platform built by physicians that goes beyond note-taking to also code your encounters in real time, handle prior authorizations, automate patient outreach, and support both outpatient and inpatient care.
Both tools listen to your visit and draft the note for you. But they are built around different priorities. This guide breaks down where each one shines so you can pick the right fit — whether your top concern is reclaiming time, capturing revenue, or running a full practice.
LucasAI vs Nabla at a glance
Here is a side-by-side summary of how the two platforms compare across the features that matter most to clinicians. Details follow in the sections below. Competitor details should be verified with the vendor before relying on them.

What is Nabla?
Nabla is an ambient AI assistant that listens to a patient encounter, transcribes the conversation, and generates a structured clinical note for the clinician to review and finalize. Its product positioning emphasizes clinician well-being — reducing the documentation burden that drives burnout — along with rapid setup and broad multilingual support. The company originated in Europe and has been expanding its presence in the United States.
For a clinician whose primary goal is to stop taking notes home, Nabla addresses that pain directly: it is designed to be quick to adopt and to work across many languages, which is valuable in diverse patient populations.
Nabla's design center is the ambient note and the clinician experience. Capabilities tied to US revenue cycle — comprehensive real-time coding, prior authorization, and billing alignment — are not the core of its positioning, so practices that depend heavily on those workflows should confirm exactly what is supported.
What is LucasAI?
LucasAI (lucashealth.ai) is an ambient clinical platform built by a team of clinicians, technologists, and entrepreneurs, headquartered in Miami, Florida. It starts from the same foundation — a real-time ambient scribe that writes your note as you talk — but treats documentation as the beginning of the workflow rather than the end of it, with a deliberate focus on the US market.
On top of the scribe, LucasAI layers:
- CodingAI — integrated, real-time CPT, CPT II, ICD-10 and E&M service-level suggestions, one-click optimization, and a Magic Addendum to keep documentation complete and compliant with US billing requirements.
- Prior AuthAI — automatically compiles the documentation needed for prior authorizations, from billing codes to risk factors.
- EmilyAI — automated patient outreach that calls patients before and after visits to close care gaps, complete screenings, and update the chart for you.
- AI document management — vision-based scanning that digitizes labs, images, and medication lists into the chart.
- Inpatient tooling — Rapid Rounds, Swift Summaries, Lightning Handoffs, and Observation/Inpatient status justification for hospital workflows, alongside full outpatient support.
- Provider & Team Mode — coordinated, multi-role workflows spanning the front desk, medical assistants, and providers.
LucasAI reports outcomes including an average 25% increase in revenue per provider, a 90% reduction in coding queries and downstream admin, and meaningful gains in compliance support for HEDIS and risk scoring.
Ambient scribe & note quality
This is the category where the two are most similar — and where Nabla is genuinely strong. Both products capture the conversation ambiently and generate a structured note (SOAP and other formats) with specialty awareness, and both support multiple languages.
LucasAI's differentiators here are real-time generation (the note is ready by the time you walk out of the room rather than after a processing step) and robust handling of blended, code-switched speech like Spanglish, where a clinician and patient move fluidly between languages mid-sentence. If your visits are bilingual, that matters.
Bottom line: for pure scribing, both are capable. If a clean ambient note and reduced burnout are the only things you need, Nabla is a reasonable choice.
Medical coding & revenue capture
This is the clearest dividing line between the two products.
Nabla centers on the ambient note and clinician well-being, and surfaces suggested codes such as ICD-10 to support billing; comprehensive, real-time coding aligned to US reimbursement is not the heart of its positioning.
LucasAI treats revenue capture as a primary job. CodingAI suggests CPT, CPT II, ICD-10 codes and E&M service levels in real time, flags under-documentation, and offers one-click optimization plus a Magic Addendum to support a compliant, defensible note. Explore the details on the LucasAI medical coding page. The company reports an average 25% revenue increase per provider and a 90% drop in coding queries.
If you are an employed physician who only cares about getting notes done, this difference may not move you. If you are an independent clinician or a US group where every correctly captured code is real revenue, it is significant — accurate coding can pay for the software many times over.
Prior auth, outreach & document capture
Beyond coding, LucasAI builds in workflows that typically fall to staff. Prior AuthAI compiles the supporting documentation for prior authorizations. EmilyAI places automated calls to patients before and after visits to close care gaps and update the chart. And AI document management uses vision to digitize labs, images, and medication lists.
Nabla's positioning centers on the ambient note and clinician well-being rather than on revenue-cycle automation such as prior authorization or outbound patient outreach; confirm exactly what is offered if these workflows matter to you.
Specialties & care settings
Nabla is positioned for outpatient and ambulatory care across a range of specialties.
LucasAI covers outpatient workflows too, but adds a dedicated inpatient product line for hospital medicine — Rapid Rounds, Swift Summaries, Lightning Handoffs, code-blue/resuscitation documentation, and Observation vs. Inpatient status justification. If you round in a hospital or work across both settings, that is a meaningful advantage for LucasAI.
US focus & languages
Nabla originated in Europe and has been expanding in the US, and it emphasizes broad multilingual support — useful for clinicians serving diverse, multilingual patient populations.
LucasAI is built with a US focus, aligning its coding, billing, and compliance workflows to US requirements, while still supporting multilingual encounters — including blended, code-switched speech such as Spanglish. For US practices whose revenue depends on accurate CPT/ICD-10/E&M capture, that alignment is a practical advantage.
Security & HIPAA compliance
Both vendors describe themselves as HIPAA compliant and will sign a Business Associate Agreement (BAA).
- Nabla describes itself as HIPAA compliant and offers a BAA; review its current security documentation for specifics such as data handling and retention.
- LucasAI is HIPAA and GDPR compliant and offers an organizational BAA, which matters for groups and any practice with international considerations.
For most U.S. practices either posture is sufficient; for multi-site organizations, LucasAI's organizational BAA and GDPR coverage are useful additions. Always review each vendor's current BAA and security documentation for your own risk assessment.
Pricing
Pricing transparency is one of LucasAI's differentiators.
Nabla pricing (2026)
- Plan-based pricing that varies by plan and organization size, and is often quoted directly by the vendor.
- Verify current plans, tiers, and any free trial directly with Nabla before comparing.
LucasAI pricing (2026)
- Free trial available
- Premium — $69.99/month
- Pro — $299/month
- Enterprise — $999/month
See the full breakdown on the LucasAI pricing page. LucasAI's plans bundle coding, prior auth, outreach, and team capabilities, so the right way to compare cost is against the combined value of a scribe plus the revenue those features capture, not against a scribe alone.
