Knowledge Engine for AI Agent Memory in 6 lines of code

Unique: Implements a dual-storage architecture where extracted triplets are simultaneously indexed in both graph and vector databases (cognee/infrastructure/databases/), enabling hybrid queries that combine structural graph traversal with semantic vector similarity. Supports custom graph models via Pydantic schemas, allowing developers to define domain-specific entity types and relationship types without modifying core extraction logic.
