Benchmark releases
Quarterly review history. The current release is the published benchmark until the next update.
Publisher. The CEM Benchmark is published and maintained by HealthTasks. We evaluate all vendors — including HealthTasks — against the same public-documentation rubric. HealthTasks capability claims are verified against our production application and public product documentation. Other vendors are scored solely from their publicly available materials.
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 available at healthtasks.ai/api/cem-benchmark.
