OpenEvidence

OpenEvidence is an AI platform for clinical decision support, giving physicians evidence-based answers to medical questions at the point of care, with citations back to the primary literature. Built on partnerships with leading medical publishers and journals, it is designed for the accuracy and traceability medicine demands — every answer shows its sources. By 2026 it had become one of the most widely adopted physician-facing AI tools in the United States, used by a large share of US doctors and handling well over a million clinical consultations a day, and reached a multi-billion-dollar valuation.
