Vera Health is a free, retrieval-first AI clinical-answer/decision-support search engine that searches over 60 million peer-reviewed papers, guidelines, and care pathways to return concise, evidence-graded, citation-linked answers to clinical questions; it's aimed at physicians, nurses, advanced-practice clinicians, pharmacists, and medical students/trainees across specialties, with emergency medicine as a particular focus area.

Doximity is the "Super-App" of healthcare. Doximity GPT is a feature embedded inside the Doximity app you already use to fax and call patients. Powered by the acquisition of 'Pathway', it now offers evidence-based clinical answers with citations. It also helps with administrative automation such as drafting prior authorization letters, patient education handouts, and referral notes in seconds.

OpenEvidence has evolved from a simple "Medical Search Engine" into a full-stack clinical assistant. While it remains the gold standard for answering complex clinical questions with peer-reviewed citations (NEJM, JAMA), OpenEvidence also now includes a suite of workflow tools designed to reduce administrative burnout. It can draft insurance appeal letters, generate patient education handouts, and even create board-style review questions for trainees, all grounded in verified medical literature rather than generic "black box" AI.
