Nym Health vs Suki (2026)
Both turn clinical activity into structured output and they remove different people from the loop. Nym codes autonomously, routing encounters straight to billing above a published confidence threshold, which is the reason to take it seriously: an autonomous coder that will not say where it stops is asking for trust it has not earned. Suki keeps the clinician central and gives them a voice command layer over the record, ordering, navigating, staging orders and asking questions of the chart, with coding assistance alongside rather than instead of the coder. These are complementary purchases for most organisations. The numbers to ask for differ: Nym's straight through rate measured against a coding audit, and Suki's accuracy on interpreting a spoken instruction, which it does not publish at all.
- It codes autonomously and routes encounters straight to billing above its confidence threshold, and it publishes that threshold, which is the disclosure this category avoids.
- For high volume standardised encounter types, autonomous coding removes the coder rather than assisting them, which is where the savings are.
- Its scope is coding rather than documentation, so it is measured on a straight through rate rather than on clinician minutes.
- The voice command layer is the product, letting a clinician order, navigate, stage orders and query the record by speaking, which no coding engine attempts.
- Coding assistance sits alongside that at the evaluation and management, hierarchical condition category and diagnosis levels rather than replacing the coder.
- Deep bidirectional integrations across four major record systems, plus a developer platform other healthcare software embeds.
This comparison is published by AI Health Index, an independent research platform that compares healthcare AI vendors objectively. Nym Health and Suki are each graded against the same capability taxonomy, from each vendor's own public materials and the regulatory record, under the AI Health Index verification standard.

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 Nym Health its top capability grade on several axes, including AI Centrality, Autonomy and Oversight Model and Model and Technology Transparency. Set against Suki, Nym Health grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and Clinical and Operational Evidence. 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 Nym Health or Suki?
On the axes where the AI Health Index separates them, Nym Health grades higher on several axes, including Autonomy and Oversight Model, Model and Technology Transparency and Clinical and Operational Evidence, and Suki grades higher on several axes, including HIPAA and BAA Posture, Security Certifications and Trust Center and EHR and Interoperability Depth. Nym Health 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 Nym Health and Suki differ most?
The widest separation the AI Health Index records between Nym Health and Suki is on Model and Technology Transparency, where Nym Health grades A and Suki 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 Nym Health and Suki grade the same?
The AI Health Index grades Nym Health and Suki the same on several axes, including AI Centrality, Model Supply Chain Disclosure and AI Safety and PHI Stewardship. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.

These sit at different points and a health system may run both, since one produces the documentation and coding suggestion at the encounter and the other codes the finished record autonomously. The number that separates them is the straight through rate, the proportion of encounters coded with no human review, measured against a coding quality audit rather than a vendor claim; ask Nym for the audit methodology and sample size. Suki publishes no accuracy rate for command interpretation and no escalation behaviour for a misheard command, which is the disclosure its own design most needs.
