Snowflake Horizon
+ Atlan
Snowflake Horizon Catalog provides built-in context and governance for AI in Snowflake. Atlan extends that context and governance across your entire data stack to drive future-proof AI use cases for both technical and business teams.
"Atlan is much more than a catalog of catalogs. It's more of a context operating system…Atlan enabled us to easily activate metadata for everything from discovery in the marketplace to AI governance to data quality to an MCP server delivering context to AI models."
