Knowtex vs Nabla
Knowtex's strength is government scale. It is a prime awardee on a VA ambient scribe contract with a shared ceiling of $775.72M and reports 79 VA medical centers live. Nabla's strength is a controlled trial. NEJM AI published a three-arm study of Nabla, DAX Copilot and usual care. Nabla cut time in note by 9.5%, DAX's change was not significant, and about 15% of treated physicians never used either tool. Knowtex's University of Rochester orthopedics pilot, with note time under one minute and pajama time down 29%, was published by the vendor.
A VA medical center takes Knowtex. A CMIO at a private system who wants controlled evidence is better served by Nabla.
Neither vendor lists a price, and Knowtex routes buyers to a demo form. Nabla reports 130-plus organizations and a $70M Series C that brought total funding to $120M.
