Glass Health is distinct from standard "search" tools. It is built to simulate a physician’s reasoning process. Instead of just finding a fact, it acts as a "second brain" for complex cases. You input a "Problem Representation" (e.g., 55y male, acute chest pain, normal EKG, tearing sensation), and Glass Health uses a specialized clinical knowledge graph to generate a prioritized Differential Diagnosis (DDx) and a drafted Assessment & Plan.
