Agentic Index
Glass Health vs Heidi (2026)
Glass Health and Heidi both combine ambient scribing with cited clinical answers, both are self serve with a free tier, and they lead with different jobs. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Glass leads with decision support: answers with inline citations, differentials and six note types, with assisted EHR workflows for Epic, eClinicalWorks, athenahealth and Elation on its Max plan and a Developer API; its plans run from a free Lite tier through 20, 90 and 200 dollars a month. Heidi leads with the scribe, in 110 languages with structured writeback to Epic, Oracle Cerner and athenahealth, plus Heidi Comms agents for patient calls and messages. On the grid Heidi is Full on integrations, human approval, security, triggers and audit trail, where Glass is Partial or None, and Glass's deployment cell is unresolved. Choose Glass for reasoning through a case; choose Heidi for documentation and writeback at scale.
On the Agentic Index healthcare agent ranking, neither Glass Health nor Heidi clears the bar, which asks for all five chart loop capabilities documented in full. Glass Health documents none of the five in full; Heidi does not document knowledge grounding and RAG in full. 4 of the 69 vendors in the lane clear it. See the healthcare agent ranking
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Glass Health and Heidi 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 Glass Health if
- Clinicians want differentials and cited answers first, with the note as a second job.
- A published plan ladder from free to 200 dollars a month suits how you buy.
- Your developers will build on a Developer API, with a monthly minimum from 250 dollars.
Choose Heidi if
- Notes should be written back as structured data into Epic, Oracle Cerner or athenahealth.
- Security controls and an audit trail must be documented in full; Heidi is Full on both.
- Patient calls and messages should be answered by agents around the clock.

Integrations & Tool Calling Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools. |
||
|
Glass HealthIntegrations & Tool Calling Assisted EHR workflows for Epic, eClinicalWorks, athenahealth and Elation come on the Max plan. There, authorized chart context can inform a Glass session, the clinician reviews outputs inside the workflow and final documentation moves through the approved EHR workflow. Epic remains the system of record, and implementation details are deferred to direct review. Glass provides no scheduling, messaging or billing and does not connect directly to EHRs through the API. It reads chart context but names no action it takes in the EHR.

HeidiIntegrations & Tool Calling Heidi writes back to the chart through named EHR integrations. In Epic it offers structured writeback and clinical task automation across Hyperspace, Hyperdrive and Haiku, in Oracle Cerner it writes back to MPage components in PowerChart and FirstNet, and with athenahealth it syncs schedules and pushes to chart. Altera, AlayaCare, eClinicalWorks, Veradigm and others are also named, along with Availity eligibility checks and Google and Microsoft 365 tools. Full EHR access sits on the Practice plan.

Workflow Orchestration Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps. |

|
Glass HealthWorkflow Orchestration Ambient scribing, clinical decision support and deep reasoning are fixed functions on the plans, and during encounters Glass identifies the chief complaint, supports a differential, suggests history questions and points to potential next steps.

Knowledge Grounding & RAG Ability to ground agent behavior in company data through document ingestion, retrieval, external knowledge APIs, semantic search, or RAG layers. |
||
|
Glass HealthKnowledge Grounding & RAG Responses are grounded in medical evidence. Glass searches clinical guidelines and medical literature in its own literature index, with citations in the text. The index is Glass's own, not one built over the customer's knowledge, and chart context from the EHR is supplied per session.

Memory & State Persistence Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer. |
||
|
Glass HealthMemory & State Persistence Patient and encounter context is carried forward across visits, so a patient's context persists from one encounter to the next, but Glass does not say how long it is kept or how to review or delete it.

|
Glass HealthHuman Oversight & Guardrails The clinician remains responsible for reviewing clinical output and completing final chart actions through the approved process, and final documentation moves through the customer's approved Epic workflow, so Epic stays the system of record.
