Abridge vs Corti (2026)
These two sit at different layers, and both get called clinical AI. Abridge is a finished enterprise scribe, named Best in KLAS for Ambient AI in 2025 and 2026, used by more than 300 health systems, embedded in Epic across Haiku, Canto and Hyperdrive, and backed by a public trust center. Corti sells its own speech, note generation and coding models through APIs and SDKs, with its own assistant on top, so integration into a record system is work a partner or health system performs. If you want a scribe running inside Epic across a health system, start with Abridge. If you are building a documentation product or need models under your own roof, start with Corti. Where they meet is disclosure, and both publish a good deal: Abridge names its subprocessors, including OpenAI, and Corti describes its pipeline in its data processing agreement and publishes dated certifications.
- It is a product rather than a platform, used by more than 300 health systems including Kaiser Permanente, Mayo Clinic, Johns Hopkins and Duke Health, with Epic depth across Haiku, Canto and Hyperdrive.
- Its trust center carries what a US procurement review asks for, with SOC 2 Type 2, HIPAA, CCPA, TX-RAMP, WCAG 2.2 AA, a named subprocessor list and an AI section covering training data and bias.
- Linked Evidence maps every part of a generated note back to the source audio, so a clinician can check any sentence before signing.
- The models ship through documented APIs and SDKs at published usage prices, with EU or US hosting, per customer keys and a sovereign cloud that runs on any cloud or on premise.
- FactsR moves review into the visit, extracting clinical facts as the consultation unfolds so the clinician can accept or adjust each one live, rather than proofreading a finished narrative.
- Language handling is built model by model, with clinical speech models for Danish and French, and NHS Grampian nurses have helped its system learn the Doric dialect of northeast Scotland.

Abridge is an enterprise ambient AI platform that turns the clinician patient conversation into a structured, billable note inside the EHR, sold to health systems rather than to individual clinicians. It partners with more than 300 health systems, including Kaiser Permanente, Mayo Clinic, Johns Hopkins, Duke Health, Memorial Sloan Kettering, Northwell, UPMC, Sutter Health and NYU Langone, and won the KLAS Research award for Ambient AI in 2025 and 2026.

Corti is a Copenhagen company that builds healthcare AI models and sells them as infrastructure. Developers and EHR companies reach its speech recognition, clinical note generation, medical coding for ICD-10 and CPT, and an agent framework through APIs and SDKs, and Corti also ships its own application, Corti Assistant, including a version registered as a Class I medical device in the UK and the EU.

Questions buyers ask
How do Abridge and Corti work with the EHR?
For Abridge, the integration is embedded in Epic Haiku and Hyperdrive, so recording, review and the finished note stay in the Epic workflow with no copy and paste step and no parallel interface. The February 2024 Epic announcement described the path as running from recording conversations in Haiku to embedding generated notes in the patient chart in Hyperdrive.
With Corti, the API streams audio, extracts facts and generates structured notes for a partner to write into its EHR. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
How are Abridge and Corti priced and sold?
Abridge reaches its 300+ health systems through institutional contracts rather than individual clinician signup, and there is no self serve path. The trust center lists a master services agreement among its legal documents, held behind an access request alongside the security documentation.
Corti gives new accounts $50 of free credits and then charges pay as you go, with speech to text at $0.0065 a minute and note generation, medical coding and agents at $4 per million input tokens and $16 per million output tokens, all drawn from one credit wallet. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
How do Abridge and Corti handle patient data?
With Abridge, the OpenAI listing indicates that content derived from the encounter reaches a third party model provider.
Corti's data processing agreement keeps personal data for the life of the contract and deletes it 30 days after termination. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.
Which settings and specialties do Abridge and Corti cover?
The clinicians platform page says Abridge is used at over 40 specialties, with a structured, specialty specific note produced for each visit.
Corti started in emergency call triage and now documents primary care, telehealth and hospital ward care, with NHS Grampian using it on a ward at Inverurie Hospital and other NHS trusts working with it elsewhere in the UK. Language coverage is built model by model, with clinical speech models for Danish and French among them, rather than claimed across a long list. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified August 4, 2026. No vendor pays for placement.

Corti publishes no business associate agreement position, and its US hosting instance and US subsidiary make that a live question in the United States. Corti's evidence is research on its models and a 2026 KLAS First Look score of 93.3, with no study of the ambient product's effect on clinician time or note quality, and its 65 percent note bloat figure has no published method. Abridge publishes no price, and what a health system pays for a partner product built on Corti is set by the partner.
