The most widely used clinical AI platform for US physicians (757K+ verified doctors, 20M+ monthly consultations), now agentic via DeepConsult multi step clinical reasoning, valued at $12B with models trained on 35M+ peer reviewed publications.

OpenEvidence is the most widely used clinical decision support platform among US physicians, with 757,000+ verified doctors, more than 40 percent of US physicians using it daily, and over 20 million clinical consultations per month. Founded in 2022 by Daniel Nadler and Zachary Ziegler, its specialized models are trained on 35M+ peer reviewed publications with content licensing partnerships including NEJM and JAMA, citing evidence for every answer. The platform has expanded from search into agentic and documentation workflows: DeepConsult, its first AI agent purpose built for physicians, handles multi step clinical reasoning tasks that combine hundreds of studies into research grade reports, while OpenEvidence Visits produces clinical documentation and OpenEvidence 2.0 added prior authorization letters, ICD-10 suggestions, order set recommendations, and discharge summary drafting. Free ad supported access for NPI verified clinicians; enterprise deployments (Epic and Cerner integration, custom knowledge bases, SOC 2 Type II) monetize per seat. Valued at $12B as of January 2026 with roughly $700M raised.

Pricing

Free for verified clinicians

Public — partialMedium variable costFree tier

What is public

The free tier is fully public: verified US clinicians get core search, literature summaries, and the DeepConsult agent at no cost, ad supported (reported CPMs of $70 to $1,000+ fund it). Enterprise per seat pricing for health system deployments is not published.

Variable cost rationale

Individual clinicians pay nothing; health system cost is per seat enterprise scoping with EHR integration and custom knowledge bases, undisclosed publicly.
