Agentic Index
Hyro vs PolyAI (2026)
Both answer patient calls with AI, and the difference is how far each reaches beyond healthcare. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Hyro is built for healthcare. Its agents answer from a knowledge graph of the organization's own webpages, APIs and Epic data, schedule through Epic, refill prescriptions through Epic's Willow module and search for physicians. Staff can trace every answer back to its sources. PolyAI serves contact centers in many industries, healthcare among them, and connects to Epic as one integration of many. Its agents run on its own Raven models or a model the customer picks, remember each caller between conversations, and are tested with simulated callers in CI. Your team can build them in Agent Studio or in code, or PolyAI's own team can run the deployment as a managed service. Choose Hyro for Epic workflows that come ready, and PolyAI for a voice platform your team can tune and extend.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Hyro and PolyAI are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 955 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Hyro if
- Scheduling, refills and physician search through Epic should arrive as named skills that deploy without training data.
- Staff should be able to unpack any answer to the logic pathway and the sources behind it.
- Payer coverage outreach through ARMR and the IT help desk belong on the same platform as patient access.
- The knowledge behind the agents should come from your own website and Epic data, and update itself as they change.
Choose PolyAI if
- Callers should be recognized between conversations, with their preferences and booking history carried forward.
- Your team wants to choose the model behind the agent, from PolyAI's Raven family to OpenAI models, Claude on Amazon Bedrock or your own endpoint.
- Every change should pass simulated caller tests that check the backend actions the agent triggered, before publishing and in CI.
- Engineers will extend agents through the Agents, Conversations and Outbound APIs, iOS and Android SDKs and the Agent Development Kit.
- Access should be set per area, such as knowledge, flows and deployments, with each member given no access, read access or edit rights.

HyroKnowledge Grounding & RAG A knowledge graph with NLU on top holds what Hyro scrapes from the health system's webpages, APIs and Epic data, and it stays updated as sources change. Answers are restricted to the data sources the customer defines, and the sources behind each response are visible. Sourcehyro.ai/responsible-airead 2026-09-29 |

PolyAIMemory & State Persistence Agent memory is a key value store keyed to the caller's phone number. It is read at the start of each turn and written at the end of a conversation for declared state keys, holding data such as preferences and booking history between conversations, and it expires at the end of the contracted retention period. No manual per caller delete path is described. SourcePolyAI, docs.poly.ai (Agent memory persistence)read 2026-09-28 |
