Avo vs OpenEvidence

OpenEvidence is free to NPI-verified physicians and funded by advertising, while Avo sells to health systems through a demo booking. OpenEvidence answers clinical questions with cited literature and guidelines, and it lists NEJM and JAMA as partners and an NCCN collaboration. The vendor states HIPAA compliance under a standard BAA and SOC 2 Type II for the Security category. Five PubMed-listed papers include comparisons with other chatbots on board-style radiology questions and AAOS guideline concordance, a secondary summary cites an NYU Langone result of 89.6% against 88.4% for UpToDate Expert AI on MedQA, and a medRxiv preprint pilot reported 31% for quick search and 39.5% for Deep Consult on subspecialty scenarios. A poster on r/Residency reported journal bias, and a poster on r/emergencymedicine reported a wrong chest x-ray and pulmonary embolism answer.

A health system's clinical standards team that wants its own guideline pathways written into the chart should drop OpenEvidence, since its pages describe literature Q&A. Avo's no-code pathways serve that team, and PubMed's AvoMD hits include no study of the product.
