Utilizes a proprietary reasoning engine that can ingest unstructured medical data (faxes, PDFs, EHR notes) and map it directly to specific insurance policy requirements with high clinical precision, bridging the gap between clinical medicine and insurance operations.

How they differentiate

Its flagship agent, 'Florence,' acts as a digital medical director capable of parsing thousands of pages of unstructured medical records in seconds to automate complex clinical reasoning rather than just administrative workflows.
