Regard vs Wellsheet (2026)
Both sit on top of the record system rather than replacing it, and both are deployed at real scale, so this is a genuine inpatient shortlist. Wellsheet is the broader team product: prioritised clinical views, narrative summaries, generated hospital course and discharge documentation, a chat agent inside the record and pathways grounded in licensed editorial content, deployed system wide at one of the largest health systems in the country across three major record platforms. Regard is the narrower and sharper one: it recommends diagnoses from the full chart and writes the note around them, with the clinician accepting or declining each recommendation and the vendor reporting how often they do. The oversight difference is the reason to care. Regard's gate is structural and measured. Wellsheet generates a wide range of clinical text with no described gate at all, which is the question to press in a pilot.
- It recommends diagnoses rather than prioritising information, which is the harder claim, and it gates that claim by having the clinician accept or decline each recommendation.
- Certified interoperability as an ONC certified health information technology module implementing the modern exchange standard, which is verified rather than asserted, with named health systems and quantified site level results.
- Its headline metric is recommendations acted on, so the vendor is reporting whether clinicians agreed with it rather than how many hospitals bought it.
- The distribution position is the strongest in this category and it is verifiable, with three major record systems named and a system wide deployment at one of the largest health systems in the United States.
- It covers the multidisciplinary team rather than one role, supporting rounding across physicians of all specialties and the wider care team, which is a different product shape from a diagnostic assistant.
- Clinical guidance in its pathways feature is grounded in licensed, editorially maintained third party content rather than in model output alone, which is a real design decision rather than a disclaimer.

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 Regard its top capability grade on AI Centrality and EHR and Interoperability Depth. Set against Wellsheet, Regard grades higher on several axes, including AI Centrality, Autonomy and Oversight Model and Security Certifications and Trust Center. Its thinnest published disclosure sits on 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 Regard or Wellsheet?
The AI Health Index grades Regard higher than Wellsheet on every axis that separates them, several axes, including AI Centrality, Autonomy and Oversight Model and Security Certifications and Trust Center. Wellsheet does not grade higher on any scored axis.
Where do Regard and Wellsheet differ most?
The widest separation the AI Health Index records between Regard and Wellsheet is on AI Centrality, where Regard grades A and Wellsheet grades B. 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 Regard and Wellsheet grade the same?
The AI Health Index grades Regard and Wellsheet the same on several axes, including Model and Technology Transparency, Model Supply Chain Disclosure and Clinical and Operational Evidence. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Regard and Wellsheet not disclosed?
At the last review, at least one of Regard and Wellsheet published thin or absent detail on Model Supply Chain Disclosure and AI Liability and Recourse. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.

Wellsheet pairs a wide generative and decision shaping surface, hospital course narratives, assessment and plan text, discharge summaries and patient specific chat answers, with no described oversight gate, no confidence threshold and no acceptance rate.
Its acquisition was confirmed in June 2026, which changes what the security and privacy questions are asking, since assurance may now rest with an acquiring organisation rather than the product; ask which entity's certifications are in scope today. Regard's regulatory credential examines record system criteria rather than diagnostic performance and no accuracy figure or validation publication was located. Both vendors surface documentation that improves reimbursement as well as clinical completeness, and neither separates the two.
