Overview
Atlan is a data catalog and context platform now positioned as "The Context Layer for AI." The product connects business logic, metadata, lineage, governance, glossary terms, metrics, quality signals, and institutional knowledge so AI agents and human teams can reason over trusted enterprise data.
Atlan's current messaging argues that enterprise AI fails when models lack business context: what data means, how teams define metrics, who owns assets, and how policies apply. Atlan addresses that with an Enterprise Data Graph, Data Marketplace, Context Agents, Context Engineering Studio, and a Context Lakehouse designed to make trusted metadata available across human and AI workflows.
For teams evaluating AI data governance tools, Atlan is a strong fit when the goal is not only cataloging data but also operationalizing context for AI agents, analytics, and governed self-service. Teams building model-facing controls should compare it with broader AI governance tools.
