Graded C on resilience. In Vannus's assessment it has not disclosed which model it runs — acceptable, with limits worth knowing.
Ambient AI clinical documentation — captures the clinician-patient conversation and drafts structured notes into the EHR. The privacy policy names the entity as Abridge AI, Inc., 30 S 15th St Ste 1550, PMB 41901, Philadelphia, PA 19102, United States, and states personal information "will be processed within the US and countries where our service providers are located".

Not disclosed. Abridge does not publish which model it runs, so this criterion is excluded and the grade rests on what we could verify. We say so rather than guess.
This is a separate question from the grade above. The grade measures resilience — whether the tool endures and whether you could leave it. This measures who can compel your data. A tool can score modestly on one and strongly on the other, and many do.
The vendor's published or catalog-recorded posture — the concrete facts this grade is built from. A full audit verifies each against the vendor's current documentation.
Vannus grades Abridge against nine dimensions of trust — data sovereignty, training privacy, compliance posture, operational resilience, exit portability, and more. The heaviest criterion asks whether the tool builds its own AI or resells someone else's model; where the vendor discloses it, the grade cites the vendor's own documentation. No paid placements — scoring is walled off from affiliate revenue. See the methodology →
