Corti vs Microsoft Dragon Copilot
Build the documentation layer or buy it, and this pair is the clearest statement of that choice in the category. Corti sells healthcare foundation models as infrastructure through documented interfaces, with sovereign cloud, any cloud or on premise deployment, language specific models built to handle accent variation, and an architecture described as a mechanism rather than as advanced reasoning. Dragon Copilot is the finished product with the widest reach, role based editions for physicians, nurses and radiologists, native embedding in the dominant record system and the fullest published account of its own failure modes anywhere in this lane. For most health systems Microsoft is the answer and Corti is not really a competitor. For an organisation that intends to own its clinical AI stack, or a software vendor embedding documentation in its own product, Corti is selling the thing Microsoft will not.
- It sells models as infrastructure through documented interfaces, so a health system or software vendor can build the documentation layer rather than adopt someone else's interface.
- Sovereign cloud, any cloud or on premise deployment removes the data residency question rather than governing it, and language specific models address accent degradation by engineering.
- Named and dated attestations, and an architecture described mechanically as a staged loop rather than as advanced reasoning.
- It is a finished product with the widest reach in the category, role based editions for physicians, nurses and radiologists, native embedding in the dominant record system and availability across ten countries.
- The published documentation set names its own failure modes, including hallucinated details in summarization and underperformance on accents and dialects not well represented in training.
- For an organisation that wants documentation working next quarter rather than a platform to build on, there is nothing to construct.

These sit at different layers and the comparison is only real for a buyer choosing between deploying a product and building on a platform, which is a strategic decision rather than a procurement one. Corti's evidence for the ambient documentation product specifically is thin, with a vendor generated note bloat figure and commissioned market research rather than clinical study.
Its compliance framing is European first, so a United States buyer should establish business associate terms explicitly. Microsoft publishes no rate card, and its own randomized efficiency result was 1.7 percent reduction in time in note and not statistically significant.
