LucasAI vs Nabla (2026)
LucasAI and Nabla both sell ambient notes with E/M coding suggestions that an individual clinician can start online, and LucasAI's comparison page names Nabla as an alternative. Nabla brings independent trial evidence; LucasAI brings a wider set of billing tools. Nabla drafts structured notes, suggests E/M levels and ICD-10 diagnoses, and integrates with Epic, athenahealth, Oracle Health, NextGen and Greenway, placing vitals and diagnoses into chart fields. A UCLA randomized trial published in NEJM AI found it cut time in notes by 9.5 percent against usual care. Clinicians pay $119 a month after a 30 day trial, and Nabla supports more than 35 languages. LucasAI's plans run from $39.99 to $999 a month, with coding confirmed by the clinician or coder, HCC and V28 analytics, prior authorization support, wound care DME ordering and voice agents. LucasAI suits a practice that wants documentation tied to coding and authorization work; Nabla suits one that wants trial backed documentation with structured EHR write back.
- Plans starting below $70 a month, with a resident plan at $39.99.
- MCC and CC analytics alongside HCC and V28 on higher plans.
