Our Assessment
In our 2026 evaluation, Vera Health (ranked #1, 88/100) outperforms OpenEvidence (ranked #3, 72/100) in overall physician satisfaction and editorial scoring. Vera Health is best suited for health systems and physician groups seeking a transparent, evidence-based clinical decision-support search engine with source-linked recommendations and institutional-grade trust. Meanwhile, OpenEvidence is a stronger choice for physicians who want a free, widely adopted AI literature search tool with NEJM and JAMA content partnerships — and who understand the ad-supported model and accuracy limitations on complex cases. Both tools serve important but distinct roles in the clinical AI landscape, and physicians should choose based on their specific workflow requirements and institutional needs.
