Atlan

Atlan is a data catalog and governance platform that helps organizations discover, document, and manage their data assets across warehouses, pipelines, and BI tools. It provides a searchable inventory of datasets along with lineage, ownership, and quality information, so teams know where data comes from and whether it can be trusted. For AI systems, this kind of catalog can act as a source of vetted context, helping ensure that agents pull from data that is current and properly governed rather than from unreliable or duplicate sources. Atlan is offered as a managed, cloud based product rather than a self hosted tool.
