Assort Health vs Hyro (2026)
If your failure mode is choosing on integration alone without asking whether you can interrogate how the agent decides what to say, weigh architecture against escalation here. Both complete transactions rather than just answering, writing to the EHR in real time. Hyro offers the clearest architectural disclosure among voice vendors in this index: a hybrid of large language models, a proprietary conversational engine, small healthcare tuned models, and purpose built knowledge graphs, which is the control argument made concrete, since a knowledge graph constrains what an agent can assert. Its evidence is enterprise grade, 45 to 50 health systems and an investing client. Assort counters with specialty depth across 22 enumerated fields and the more explicit escalation trigger, a warm handoff on clinical urgency, though neither publishes its transfer trigger criteria.
- Specialty depth as the differentiator: a Synapse model trained across 22 enumerated specialties from orthopedics to oncology, with real time write back into more than 20 EHRs including native Epic and athenahealth.
- The more explicit escalation trigger: a warm handoff fires specifically when a patient signals clinical urgency, identity cannot be confirmed, or required details are missing.
- Purpose built for the specialty practice and multi specialty group, with named deployments across a broad specialty range rather than a concentration in large enterprise systems.
- The clearest architecture in the lane: a documented hybrid of large language models, a proprietary conversational engine, small healthcare tuned models, and knowledge graphs, which lets a buyer interrogate how the agent is constrained rather than trust a black box.
- Enterprise grade adoption independently corroborated: 45 to 50 US health systems and more than 30 million patients engaged, named clients including Intermountain and Baptist, and Bon Secours Mercy Health invested as a client, a stronger signal than a logo.
- Completes the transaction through direct API into Epic and CRMs, booking or refilling rather than routing, which separates this tier from IVR replacement, plus a premium fit for large systems.

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 Assort Health its top capability grade on AI Centrality, EHR and Interoperability Depth and Setting and Specialty Coverage. Set against Hyro, Assort Health grades higher on Setting and Specialty Coverage. 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 Assort Health or Hyro?
On the axes where the AI Health Index separates them, Assort Health grades higher on Setting and Specialty Coverage, and Hyro grades higher on Model and Technology Transparency, Clinical and Operational Evidence and AI Governance and Bias Disclosure. Hyro 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 Assort Health and Hyro differ most?
The widest separation the AI Health Index records between Assort Health and Hyro is on Setting and Specialty Coverage, where Assort Health grades A and Hyro grades B. That axis sits in the Commercial group, so it should carry the most weight for a buyer whose binding constraint is contracting, scope and what the price actually covers.
Where do Assort Health and Hyro grade the same?
The AI Health Index grades Assort Health and Hyro the same on several axes, including AI Centrality, Autonomy and Oversight Model and Model Supply Chain Disclosure. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.

Other published head to head assessments involving these vendors or their closest peers. The full set for this category is on the Patient Voice Agents page.
Both sit in the deeper integration tier and both are graded on vendor reported metrics; Assort's resolution figures and Hyro's up to 85 percent routine resolution are each vendor stated without an independent definition of what counts as resolved.
The oversight gap is shared: neither publishes the confidence threshold or trigger criteria at which a conversation transfers to a human, which matters most for prescription refill requests, though Assort at least names the conditions that prompt a handoff. Neither publishes pricing; Hyro is positioned as a premium tier chosen by large systems, while smaller practices are typically served by more general purpose alternatives. Neither record carries a graded security or HIPAA axis here, so a buyer should confirm attestations directly. Voice performance can vary across accent and dialect.
