Rill lets you define BI workflows—models, metrics, dashboards and access policies—in YAML and SQL, and runs queries on engines like ClickHouse or DuckDB. It adds conversational and agent-driven interfaces for natural-language querying and automated dashboard generation, with real-time performance, embeddable dashboards, and Git-backed deployments.

• Full BI stack (models, metrics, dashboards, agent config) spins up from three prompts via `rill init`, then `rill start` gives an instant local UI.
• Metrics-as-code approach: SQL models plus YAML-defined dimensions/measures let Rill generate queries on the fly, returning sub-second results even at billions of rows.
• Same semantic layer powers both natural-language conversational BI and traditional SQL-based analyst workflows.
• Deployment is Git/CI-CD native via `rill deploy`, with dashboards embeddable and metrics exposed through a REST API.
