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
Memvid
No database or infra to run — memory ships as one portable, offline .mv2 file with sub-5ms retrieval, unlike server-based memory layers.
- No vector DB or RAG pipeline to run
- Works fully offline
- Model-agnostic and multimodal
- Apache-2.0 licensed
- Append-only, versioned storage
- Video-frame approach is novel and debated
- Smaller ecosystem than mem0-style stacks
- Young commercial offering (2026)
- Best for embed/edge, not multi-writer servers
