Lumen

Agent-based framework turning natural language into SQL, charts, and dashboards.

Webfreeglobal

Lumen is an open-source, agent-based framework that turns natural-language questions into SQL, charts, and dashboards over DuckDB and other data sources. It lets an analyst explore and report on data conversationally instead of writing queries and chart code by hand. It's built for data analysts who want natural-language data exploration and reporting.
