Notable vs XCaliber Health (2026)
Two agent platforms for provider operations, at different sizes. Notable runs agents across patient access, revenue cycle, care operations and the contact center for health systems and health plans. It reports 12,000 sites of care and 1.5 million tasks automated a day, with a no code builder and a connector hub that reads and writes across Epic, Oracle Health, MEDITECH, athenahealth and payer portals. XCaliber Health deploys role based assistants inside the systems a provider already runs, from patient navigation and care coordination to a quality and risk analyst and an AI Nurse offering triage support. Underneath is a data gateway with FHIR access, deployable in the cloud, self hosted or hybrid. A health system that wants agents across many named workflows at scale looks at Notable. A provider that wants assistants on top of its existing systems, possibly self hosted, looks at XCaliber.
- Workflow coverage across the operation: intake and registration, scheduling, referrals, estimates, prior authorization, appeals, denials, care gap outreach and risk adjustment.
- A trust center listing HITRUST, SOC 2 Type 2, PCI DSS and ISO/IEC 27001.
- Named customers across health systems and a health plan, including CommonSpirit Health, MUSC Health and Security Health Plan.
- Deployment choice: cloud, self hosted or hybrid, for an organization that will not send coordination data outside its estate.
- A data gateway with read and write access through FHIR and document extraction, a public FHIR resource catalog, and listings on the athenahealth and AVIA marketplaces.
- Care gap and value based care work through its quality and risk analyst assistant.
