ClinicalKey AI vs DynaMed
Two publisher owned reference products with generative layers, competing for the same institutional subscription, and they differ in what they have chosen to prove. ClinicalKey AI is stronger on the mechanics of trust: paragraph level traceability, an enumerated corpus with a daily refresh, and a published clinician centred evaluation of its own generative answers. DynaMed is stronger on the mechanics of buying and deploying: an Epic marketplace listing that was actually reviewed, a public webstore with a free trial, and a product family that separates physician, nursing and pharmacy readers rather than serving one corpus to all three. Neither publishes a security attestation of any kind, and neither has measured how often its generative layer reasons wrongly from a correct citation, which is the failure this category has yet to confront.
- Provenance at paragraph level rather than document level, so verifying a claim costs one click into the exact passage rather than a search through a topic.
- The corpus composition is published in detail, with named texts, named society guidelines, named journals and government sources, and the vendor has published a structured evaluation framework applied to its own generative answers.
- International reach, available in more than 50 countries with multi language support, which is the widest geographic footprint in this category.
- The integration credential clears a marketplace review rather than resting on a claim, with a listing in the Epic App Orchard from June 2021, single sign on and multi organisation affiliation for a single clinician.
- The generative layer is explicitly bounded and labelled, over the vendor's own content sets, with a published principle limiting generative use in user facing applications rather than expanding it.
- You can buy it and try it. A public webstore with a subscribe route and a free trial sells individual and trainee tiers directly, against a product whose only published price is a free year for medical students.

Neither vendor publishes a security attestation, trust centre, penetration testing cadence or vulnerability disclosure programme, and both health privacy positions are assertions rather than published agreements. Both grade C on AI centrality under the same rule: the asset is a decades old curated corpus and the model is a retrieval layer over it, which describes the mechanism rather than the quality.
Neither publishes a bias evaluation, subgroup analysis or error taxonomy for the generative layer, so neither addresses the failure mode this category most needs measured, an interpretive error sitting underneath a correctly attributed citation.
