Publisher. The CEM Benchmark is published and maintained by HealthTasks. All vendors — including HealthTasks — are evaluated against the same public-documentation rubric using publicly available primary sources.
Methodology. Scores measure cited capability coverage from primary vendor sources (product pages, help centers, API docs) — not subjective quality, customer satisfaction, or market share. A capability marked not supported means we could not verify it from public documentation, not that the feature definitively does not exist. Capabilities without quotable excerpts are not scored as supported.
Process. This research is produced through automated AI-assisted evaluation and human review, refreshed quarterly. AI can make mistakes — we recommend independent verification before relying on these results. Machine-readable data is at /benchmark/dataset.
Updates. We review submitted corrections and new primary-source citations against the same public-documentation rubric. Accepted updates may be published as a changelog update to the current release or in the next quarterly review. Submit a change request.
