Heidi Health vs Microsoft Dragon Copilot (2026)
Both publish substantial governance material, arriving at it from opposite directions. Heidi holds ISO 42001, the audited AI management system standard, and states it is the first ambient scribe to do so, alongside ISO 27001, ISO 9001 and a SOC 2 Type II scoped to all five criteria including privacy. Dragon Copilot holds fewer named attestations for the product itself but publishes far more about the model, naming its limitations, its sub processors and its underperformance on some accents and dialects. Heidi also publishes real prices and reaches 110 languages across 190 countries; Dragon Copilot publishes none and reaches ten. The constraint that usually decides it is commercial rather than technical: Heidi's push to chart comes with its Teams plan, so a United States health system that needs integration is buying Teams, priced on request.
- The certification stack is broad and independently examined: ISO 42001 for AI management, ISO/IEC 27001:2022, ISO 9001, and a SOC 2 Type II covering all five trust services criteria including privacy.
- Language and residency reach: 110 languages across 190 countries and more than 200 specialties, with region appropriate data residency operated as a design property, United States data held for United States users and Canadian data held in Canada.
- You can price it and try it. A free tier with unlimited transcription, a Clinician tier at $110 per user per month billed annually or $150 monthly, and Teams priced on request, against a competitor that quotes everything through sales.
- Native embedding rather than plan bound integration. Heidi's push to chart comes with its Teams plan, with the Free and Clinician plans relying on templates and copy workflows. Dragon Copilot is embedded in the record with structured capture.
- Model level disclosure. Heidi publishes no model name, its accuracy results are preprints by its own team on simulated visits, and its governance strength sits at the management system level. Microsoft publishes named limitations, error modes and a sub processor list for the product itself.

Questions buyers ask
How do Heidi Health and Microsoft Dragon Copilot work with the EHR?
For Heidi Health, the Teams integrations reach the main hospital and ambulatory systems. For Epic, Heidi describes ambient documentation, structured writeback and clinical task automation across Hyperspace, Hyperdrive and Haiku.
With Microsoft Dragon Copilot, the product is embedded natively there, with Android and iOS parity and an Epic nursing app path for flowsheet capture, and the web application launches through SMART on FHIR R4. A partner Developer Kit lets a record system vendor embed the whole workflow, so recording is captured and the summary delivered without clinical content leaving the EHR.

How are Heidi Health and Microsoft Dragon Copilot priced and sold?
In Heidi Health's case, a Max seat carries five times the usage allowance of a Standard seat for agents and Routines, and costs $299 per user per month billed annually. Scribing and evidence questions never draw on that allowance, and Heidi says it never charges overages.

How do Heidi Health and Microsoft Dragon Copilot handle patient data?
With Heidi Health, data is never used for secondary purposes such as model training or commercialization, and clinical data is never shared or sold. Identifiable details are removed from transcripts and notes and processed separately from the rest.
Microsoft says the process meets the HIPAA deidentification standard, the GDPR standard for anonymization and Canadian guidance under PIPEDA and Quebec Law 25. The resulting data is used to improve Dragon Copilot's models, which Microsoft says are trained solely on anonymized data.

For Heidi Health, the company reports around 2.8 million patient visits a week in 110 languages from 190 countries, and states coverage of more than 200 specialties.
With Microsoft Dragon Copilot, language support follows the product documentation. Only languages listed there are supported for speech to text and ambient summarization in a given locale, and multilingual mode must be enabled by an organization administrator before clinicians can use it.

Related comparisons
Other published head to head assessments involving these vendors or their closest peers.
Neither vendor publishes a note accuracy or error rate measured on live encounters, so the comparison rests on certification, coverage and integration rather than on measured output quality. Heidi's own research team has posted preprints on note error rates using simulated visits; no outside evaluation is published. Microsoft publishes no rate card for Dragon Copilot. ISO 42001 certifies how an organization governs its AI, not the performance of any particular model.
