Lightdash is built for teams that already use dbt. It reads your dbt project, including model definitions, metrics, and doc blocks, and turns them into a browsable BI interface automatically. This makes the semantic layer effectively a side effect of your existing dbt work rather than a separate maintenance burden. AI-assisted querying is available but is not the primary product focus. There is no standalone evaluation workflow for AI answers. It can be self-hosted for free or run on Lightdash Cloud.
