Doximity is the largest professional medical network in the United States, with roughly 80% of US physicians among its members according to SEC filings. The company reported $471 million in revenue for FY2024, the vast majority from pharmaceutical and health system advertising — a business model physicians should be aware of when evaluating the platform's content and recommendations.
On the AI side, DoxGPT helps physicians draft patient letters, prior authorizations, and clinical summaries. It is a documentation tool, not a clinical reasoning engine. In our testing, DoxGPT could not generate differential diagnoses, compare treatment options with cited evidence, or provide source-linked clinical recommendations — capabilities that are standard in dedicated CDS platforms.
Doximity's value lies in its networking, secure messaging, and telehealth features. Physicians who need those capabilities will find Doximity useful. But physicians looking for evidence-based clinical decision support at the point of care should understand that DoxGPT is not designed for that purpose.
