Cognee - AI Memory and Knowledge Graph Platform user interface

Cognee is built for AI systems that need persistent memory and relationship-aware retrieval, not just flat vector similarity lookups.

Key Features

  • Knowledge Graph Construction: Turn raw content into linked entities and relationships.
  • Semantic Retrieval Layer: Combine embeddings with contextual retrieval patterns.
  • Model Provider Flexibility: Integrate different LLM and embedding stacks.
  • MCP Ecosystem Support: Connect with assistant workflows using MCP patterns.
  • API-First Design: Ingest, process, and query through service APIs.
  • Storage Backends: Support multiple persistence strategies for different use cases.

Why Choose Cognee?

  • You are building RAG apps with memory requirements.
  • You need better context structure than a plain vector DB.
  • You want private data ownership for AI workloads.

Docker Deployment

Cognee is commonly deployed with PostgreSQL/pgvector and related service components. Use persistent volumes and secure API key management.

Getting Started

  1. Deploy Cognee and its data services.
  2. Configure model provider credentials.
