3. Clinical Decision Support & Point-of-Care Evidence    

This category covers conversational AI tools that let clinicians ask natural-language medical questions and receive answers synthesized from peer-reviewed literature (NEJM, JAMA, Cochrane, NCCN guidelines, and hundreds of other journals), typically with inline citations back to the source. Some tools go further and act as structured clinical-decision-support (CDS) engines that generate differential diagnoses, suggested assessment-and-plan drafts, and flag drug interactions or dosing concerns directly from the patient encounter, rather than simply answering an isolated question. This is distinct from, and complementary to, ambient scribing: scribes document what happened in the visit, while CDS tools help reason about what should happen next. Notably, this is one of the few categories in medical AI with genuinely useful free tiers — OpenEvidence is free for all verified U.S. clinicians, and Glass Health offers a free "Lite" plan — because these tools are typically monetized through pharma/publisher partnerships or freemium upsells rather than direct subscription fees alone. As with all generative AI in medicine, outputs are decision support, not a diagnosis or a substitute for clinical judgment, and require professional review.
