Hippocratic AI vs Hyro (2026)
If your failure mode is shortlisting the two most polished enterprise voice vendors as interchangeable, they are the most architecturally transparent in the lane and they do opposite jobs. Hyro completes front office transactions, scheduling, registration, routing, and refills, through direct API into Epic and CRMs, and documents a hybrid architecture of language models, a conversational engine, small tuned models, and knowledge graphs. Hippocratic AI runs non diagnostic clinical outreach and is engineered as a safety system: agents barred from diagnosis and prescribing, a Polaris constellation that can end a non compliant call, certification by thousands of nurses and physicians, and the strongest security posture in this index. Both let a buyer interrogate how the agent is built. Choose Hyro to automate the front desk, Hippocratic to make clinical outreach calls with the guardrails that job demands.
- Engineered for clinical outreach safety: agents barred from diagnosis and prescribing, a constellation of more than 25 task specific models including dedicated safety and medication agents that can end a non compliant conversation, and certification by thousands of nurses and physicians.
- The strongest security and stewardship posture in the index, SOC 2 Type 2 plus HITRUST e1 across the full platform with a named CISO, alongside published safety research and a published safety score.
- Commercially transparent in a lane that mostly is not: a published 9 dollars per agent hour and more than 300 prebuilt agents across 25 specialties.
- Built to complete front office transactions, not clinical calls: direct API into Epic and CRMs so agents book and refill rather than route, the capability that separates this tier from IVR replacement.
- Equally interrogable architecture for the administrative job: a documented hybrid of LLMs, a conversational engine, small healthcare tuned models, and knowledge graphs, purpose built for controllability.
- Enterprise proven across 45 to 50 health systems with more than 30 million patients engaged, named clients, an investing client, and a 2026 Fierce 15 selection.

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 Hippocratic AI its top capability grade on several axes, including AI Centrality, Autonomy and Oversight Model and Model and Technology Transparency. Set against Hyro, Hippocratic AI grades higher on several axes, including Autonomy and Oversight Model, Model Supply Chain Disclosure and AI Safety and PHI Stewardship. 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.

These do different jobs, so the choice is scope first. Both are strong on architectural transparency, but their evidence differs in kind: Hippocratic publishes safety research and a safety score yet its clinical outcome claims are vendor reported without methodology or comparison groups, and its governance sits at B for the absence of a published bias evaluation; Hyro's adoption is independently corroborated but its up to 85 percent resolution figure is vendor stated without a definition of routine, and it does not publish transfer trigger criteria.
On security the records diverge sharply: Hippocratic carries named, dated SOC 2 Type 2 and HITRUST e1 in this index, while Hyro's record carries no graded security or HIPAA axis, so confirm its attestations directly. Hippocratic publishes a rate; Hyro does not. Voice accuracy varies across accent and dialect.
