Atlan is a modern data catalog and collaboration workspace designed for the data mesh era — where data is produced and consumed across many teams and sources rather than flowing through a central data warehouse managed by a single team. The platform emphasises collaboration, business context, and discoverability alongside traditional catalog metadata.
AI search across all data assets allows finding tables, columns, dashboards, and ML models through natural language — 'find customer revenue tables updated in the last week' returns matching assets from across the connected data environment. For data teams where finding the right data asset before using it is a significant time investment, AI search dramatically reduces discovery time.
Auto-generated documentation uses AI to generate descriptions of data assets from their schema, query patterns, and upstream transformations — reducing the manual documentation work that keeps data catalogs perpetually out of date.
Lineage integration connects to data warehouses, dbt, Airflow, and BI tools to build end-to-end lineage showing how data flows through the entire data stack — from source systems through transformations to dashboards. Business users can trace where a dashboard number comes from without technical investigation.
Data governance workflows route data access requests, enforce data classification policies, and track consent and privacy obligations — embedding governance into the data discovery workflow rather than requiring a separate governance system.
Atlan AI runs as llm assistant software built around text and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
The capabilities that matter most for teams evaluating Atlan AI.
Natural language search across all connected data assets enabling discovery by describing data need rather than knowing exact table names or locations.
AI-generated descriptions of data assets from schema and usage patterns, reducing the manual documentation work that prevents catalog completeness.
Connects sources, transformations (dbt, Airflow), and BI tools showing complete data flow from raw sources to dashboards for impact analysis and business context.
