OpenEvidence

OpenEvidence is an AI search tool. A medical question answering platform for clinicians, built on licensed full text from NEJM, JAMA, Nature, Cochrane and NCCN guidelines. It answers clinical queries with sourced literature and offers task templates for prior authorization letters, exam question writing and MOC exam preparation.

OpenEvidence is a medical knowledge platform built for clinicians rather than general consumers. It answers clinical questions using content drawn from peer-reviewed research, and the company positions it as America's official medical knowledge platform. The distinguishing feature is the source base: official AI partnerships with the New England Journal of Medicine, JAMA and the JAMA Network specialty journals, Nature and the Nature Portfolio, Cochrane Systematic Reviews, and an official collaboration with the National Comprehensive Cancer Network covering NCCN Guidelines treatment algorithms. Society partnerships extend across NCCN, AAP, ACC, ADA, AAFP, NORD, ACOG, AUA, AAO, ACEP and a longer roster that includes neurology, hematology, addiction medicine and sleep organizations. In practice a clinician poses a question in plain language and receives an answer tied to that licensed literature. Because figures, tables, multimedia and full text are part of the indexed material, responses can point back to the specific paper or guideline rather than to an unsourced synthesis. The homepage also surfaces ready-made workflows beyond straight question answering: drafting a prior authorization letter, writing exam questions, and preparing for MOC exams. The platform states that it is HIPAA compliant, and its privacy notice says searches and submitted content are not sold or shared, with an opt-out for advertising measurement sharing. The audience is healthcare professionals: physicians, residents, advanced practice providers, pharmacists and students who need fast literature review at the point of care, plus educators building assessment material and clinicians maintaining board certification. Compared with general purpose chatbots, OpenEvidence trades breadth for provenance, and compared with traditional literature search tools it trades exhaustive query syntax for conversational retrieval over a curated corpus. What the homepage does not disclose matters for budgeting and rollout. No pricing tiers, no subscription terms, no mobile apps and no integration documentation appear there, so anyone evaluating it for a practice or health system should confirm commercial terms, device support and EHR connectivity directly before committing.
