+### Semantic Knowledge Bases
+
+Semantic Knowledge Bases provide a vector-searchable representation of your database schema:
+
+-   Create a semantic KB (`aidb.create_semantic_kb()`) to index schema metadata
+-   Search for tables, views, and columns using natural language
+-   Create semantic aliases for reusable, parameterized SQL queries
+
+Use cases:
+
+-   Text-to-SQL context retrieval for AI agents
+-   Schema discovery and exploration
+-   Building centralized query libraries
+
+See [Semantic Knowledge Base](semantic_knowledge_base/).
