Hippocratic AI vs Hyro (2026)
Both sell conversational agents to health systems, and they work different parts of the patient relationship. Hippocratic AI runs clinical calls that are not diagnostic: follow up after discharge, chronic care check ins, screening outreach, adherence and trial enrollment, with clinical judgment escalated to licensed nurses under a published scope. Hyro runs the access layer across the call center, website, text and mobile apps: scheduling, provider search, refill requests, MyChart password resets and help desk requests, with answers drawn from sources the health system approves and complex calls handed to staff. Choose Hippocratic AI for clinical outreach; choose Hyro to take routine access requests off the call center.
- The calls are clinical: follow ups, check ins, adherence and screening.
- A published scope that rules out diagnosis matters to your clinicians.
- You need agents for payer or life sciences programs as well.
- Routine requests, from scheduling and refills to password resets, are swamping the call center.
- Answers should come only from sources your health system approves.
- The agent should work across web, text and mobile as well as the phone.

How do Hippocratic AI and Hyro handle patient data?
In Hippocratic AI's case, the company publishes the parts that catch a wrong answer: support models that check medications, labs and escalation during the call, an online judge before a patient is told something and an offline model that re-reads calls, a call supervisor that scores every call, and clinician testing before an agent goes live.
For Hyro, the privacy policy adds that anonymized or de-identified information may be used and shared without restriction, for example to improve the services, and that an internal retention policy prevents perpetual retention, with no periods given. By design the customer defines and restricts the knowledge sources an agent may use, and each foundation model step receives only the context it needs.

Which settings and specialties do Hippocratic AI and Hyro cover?
With Hippocratic AI, the company lists agents for providers, payers and life sciences across 17 specialty filters and use cases from post-discharge calls and screening outreach to adverse event intake and trial retention, and it names what it will not do: hospice, mental health disorders and children under two.
In Hyro's case, coverage is organized by organization and channel rather than specialty: health systems, federally qualified health centers (sold on multilingual access), children's hospitals and payers (member and agent experience), across calls, websites, text and mobile apps, with an outbound line for ACA and Medicaid coverage renewal outreach. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
