 Choose the observability tool that fits your needs:
 
-✅ [**Elementary Open Source**](https://docs.elementary-data.com/oss/oss-introduction) – A powerful, self-hosted tool for teams that want full control.
+✅ [**Elementary OSS**](https://docs.elementary-data.com/oss/oss-introduction) – A powerful open-source data observability layer for dbt. It runs in your pipeline, captures rich metadata and artifacts, and includes alerting and reporting to help engineers surface issues early.
 
-✅ [**Elementary Cloud Platform**](https://docs.elementary-data.com/cloud/introduction) – A fully managed, enterprise-ready solution with **automated ML-powered anomaly detection, flexible data discovery, integrated incident management, and collaboration tools**—all with minimal setup and infrastructure maintenance.
+✅ [**Elementary Cloud**](https://docs.elementary-data.com/cloud/introduction) – A managed, AI-driven control plane for observability, quality, governance, and discovery. It includes automated ML monitoring, column-level lineage from source to BI, a built-in catalog, and AI agents that scale reliability workflows. Cloud supports both engineers and business users, enabling technical depth and simple self-service in one place.
