Fourier Health vs Regard (2026)
Both read the whole chart and they make claims of very different size. Fourier produces summaries shaped to a specific use case, ingesting faxes and handwritten notes directly, with every statement attributed to its source and a clinician network reviewing the output. Regard recommends diagnoses and writes the note around them, gated by a clinician accepting or declining each one, with certified interoperability and quantified results at named sites. A summary you can verify line by line and a diagnostic suggestion are not the same object, and the evidence bar should scale accordingly. Fourier's review network is worth interrogating separately, because it means people outside your organisation are reading your patients' records with no published terms.
- Summaries are shaped to the use case with every statement attributed to its source, and a clinician network reviews the output.
- It ingests the messy reality directly, including faxes, handwritten notes and records retrieved through exchanges.
- For a buyer who wants finished readable summaries rather than a recommendation, the claim is smaller and easier to check.
- It recommends diagnoses from the full record rather than summarising, and writes the note around the recommendation.
- The oversight gate is structural, with the clinician accepting or declining each recommendation and the vendor reporting how often they do.
- Interoperability is certified rather than claimed, with named deployments and quantified site level results.

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 Fourier Health its top capability grade on AI Centrality. Set against Regard, Fourier Health grades higher 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 Fourier Health or Regard?
On the axes where the AI Health Index separates them, Fourier Health grades higher on Model Supply Chain Disclosure, and Regard grades higher on Clinical and Operational Evidence, Security Certifications and Trust Center and EHR and Interoperability Depth. Regard 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 Fourier Health and Regard differ most?
The widest separation the AI Health Index records between Fourier Health and Regard is on Model Supply Chain Disclosure, where Fourier Health grades C and Regard grades D. 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 Fourier Health and Regard grade the same?
The AI Health Index grades Fourier Health and Regard the same on several axes, including AI Centrality, Autonomy and Oversight Model and Model and Technology Transparency. 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 Fourier Health and Regard not disclosed?
At the last review, at least one of Fourier Health and Regard published thin or absent detail on Model Supply Chain Disclosure. 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.

The size of the claim differs and the evidence bar should scale with it: a traceable summary can be checked sentence by sentence, while a diagnostic recommendation is a clinical assertion about a patient, and Regard's certification examines record system criteria rather than diagnostic performance.
Fourier's clinician review network is both its strongest control and its largest exposure, since reviewers outside the customer organisation read patient records with no contracting terms located. Neither publishes an omission rate.
