Abridge vs Sunoh.ai (2026)
For a practice on eClinicalWorks this is the real ambient documentation decision: take the scribe built into the record system, or buy the enterprise specialist and integrate it. Sunoh is native, pre fills orders including labs, imaging, medications and referrals, publishes 149 dollars per provider per month and offers a free trial with no contract. Abridge is the most deployed ambient platform in the category, Best in KLAS in consecutive years across more than two hundred and fifty health systems, with a full trust centre and coverage across outpatient, inpatient and emergency care. For a small ambulatory practice, Sunoh's price, trial and native order pre fill are hard to argue with. For a large organisation with acute settings and a governance committee, Abridge publishes what Sunoh does not, including an attestation reachable in its own materials.
- Best in KLAS for ambient AI in consecutive years across more than two hundred and fifty health systems, with a full trust centre naming attestations, sub processors and a dedicated AI section.
- Depth across outpatient, inpatient and emergency settings with dozens of specialties, and integration depth in the dominant record system plus a second named platform.
- The documentation is pointed at the revenue cycle rather than stopping at the note, which matters if the programme has to justify itself on coding.
- It publishes a price and a trial, at a per provider monthly rate with no contract, where the alternative quotes everything through enterprise sales.
- It is native inside the record system a very large ambulatory base already runs, writing structured content into the progress note rather than syncing from outside.
- Order pre fill covers labs, imaging, medications, referrals and follow up appointments, which is work removed rather than prompted for.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Abridge its top capability grade on several axes, including AI Centrality, Autonomy and Oversight Model and Model Supply Chain Disclosure. Set against Sunoh.ai, Abridge grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and Model Supply Chain Disclosure. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Abridge or Sunoh.ai?
On the axes where the AI Health Index separates them, Abridge grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and Model Supply Chain Disclosure, and Sunoh.ai grades higher on Commercial Transparency. Abridge leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Abridge and Sunoh.ai differ most?
The widest separation the AI Health Index records between Abridge and Sunoh.ai is on Autonomy and Oversight Model, where Abridge grades A and Sunoh.ai grades C. That axis sits in the AI Capability group, so it should carry the most weight for a buyer whose binding constraint is how much of the work the model itself is trusted to do.
Where do Abridge and Sunoh.ai grade the same?
The AI Health Index grades Abridge and Sunoh.ai the same on several axes, including AI Centrality, AI Safety and PHI Stewardship and HIPAA and BAA Posture. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.

Sunoh's security attestation is asserted only on third party comparison pages, several published by competitors, and was not reachable in the vendor's own materials across two passes, so treat it as unverified rather than as a claim to weigh. Its adoption figures are inconsistent across its own site and its audio retention window is third party reported. Neither vendor publishes an accuracy figure or a bias and accent performance analysis. Neither publishes an order accuracy rate, which matters more for the product that pre fills orders than for the one that does not.
