Glass Health vs OpenEvidence
Both put a language model between a clinician and the literature, and only one of them takes the patient into account. OpenEvidence answers the clinical question from published evidence and states in its own terms that it is not a diagnostic service, with eleven independent studies behind it and partnerships supplying current primary literature. Glass takes the case description and returns a ranked differential with suggested workups plus a drafted assessment and plan, which is a patient specific output and a materially larger claim, and it is the only one of the two to have submitted itself to an external physician validated safety benchmark. That external evaluation is the strongest thing on either record. The line to keep clear is that answering what the evidence says and telling a clinician what this patient probably has are different products with different obligations attached.
- It was evaluated in an external physician validated clinical safety benchmark run by parties it did not control, and published its placement, which is the strongest independent safety signal in this part of the index.
- Reasoning and documentation happen in one pass, so the differential, the workup suggestions and the drafted note come out of the same encounter rather than two products.
- It states its own weakness plainly, that reasoning is strongest on common presentations and weaker on complex multi system cases, which is a disclosure almost nobody here offers.
- The independent literature is deeper, with a systematic review identifying eleven studies evaluating this product across two years.
- Named partnerships with major journals and a systematic review publisher supply the corpus, and enterprise deployment inside Epic is documented at named health systems.
- It is free to verified United States clinicians with native mobile applications, so a clinician can use it today without any institutional decision.

The two products stop in different places and that boundary matters legally as well as clinically: one answers what the evidence says with an explicit statement that it is not a diagnostic service, the other produces a ranked differential for a specific patient, which is a patient specific output carrying obligations that a reference answer does not.
Glass publishes no security attestation across repeated searches and no retention or training use position despite processing protected health information at depth. OpenEvidence is funded by pharmaceutical and device advertising displayed beside clinical answers, governed by a published policy worth reading before deployment.
