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
Hindsight
Goes beyond storing facts: agents reflect on past runs to update beliefs and avoid repeating mistakes, topping LongMemEval for long-horizon recall.
- Reflection: agents learn from experience
- Top LongMemEval accuracy (91.4%)
- MIT-licensed, self-hostable
- Human-like memory networks
- Managed Hindsight Cloud option
- New (2026), small ecosystem so far
- Tied to Vectorize's stack and roadmap
- Reflection adds LLM cost and latency
