About

OpenMD is a medical reference service that makes reliable medical information easier to find, understand, and use. OpenMD searches billions of documents from government agencies, global health organizations, medical journals, and established reference sources.

OpenMD searches only a curated selection of established medical sources, so credible information is not lost in a mix of promotional, sensationalized, and user-generated content.

Many professional medical resources are available only through subscriptions. OpenMD prioritizes freely accessible content whenever possible.

OpenMD AI provides clear answers to medical questions, with citations to published research and guidelines from medical societies and agencies. It also prepares clinical evidence briefs, explains medical documents in plain language, and assists with clinical calculations and medical coding.

OpenMD also maintains an expert-reviewed directory of trusted medical information sources, selected for subject expertise and editorial standards.
