The honest brief

Cognee

Builds an LLM-derived knowledge graph alongside embeddings, so recall follows relationships, not just vector similarity.

  • Self-hostable Python SDK
  • Recall follows concept relationships
  • Bring your own LLM/embedding provider
  • Newer, smaller ecosystem
  • Cognify pipeline adds LLM cost
  • Self-host setup overhead

memU

Stores memories as a hierarchical file system rather than only vector embeddings, cutting context tokens roughly 10x for always-on agents.

  • Built for proactive, always-on agents
  • Semantic recall via vector indexing
  • Self-host or hosted cloud API
  • Multimodal memory ingestion
  • Younger project, evolving API
  • Smaller ecosystem than vector DBs
  • Hosted pricing details limited
