DAX Copilot vs Nabla
One randomized trial put both tools in the same academic health system, and only Nabla's arm reached significance. In the NEJM AI study of 238 outpatient physicians, Nabla users cut time in note by 9.5% (p=.02) while DAX users cut it by 1.7%, not significant. Usage was low in both, 29.5% of visits for Nabla and 33.5% for DAX. A department chief choosing on measured time saved therefore has data only for Nabla. DAX still has the stronger case in a Microsoft shop. A Microsoft blog says audio and transcripts fall under the hospital's existing BAA with Microsoft, the Azure environment is HITRUST CSF certified, and Epic needs the May 2025 release or later. Nabla lists SOC 2 Type II and ISO 27001, and its BAA is not confirmed on an official page. Both price by quote. A reseller lists DAX at $369 per user per month plus $700 setup on a 12-month commitment, and Nabla's terms bill a monthly per-user fee in euros excluding VAT.
