Cognee is a pragmatic RAG orchestration layer combining vector search, graph DBs, and some cognitive science framing. The quickstart works—you can actually ingest text and query it. The research paper (arXiv 2505.24478) on KG+LLM interfaces gives it real grounding, not vaporware. But: (1) the core value prop is 'we wrap these DBs + embeddings for you,' which is honest but not novel; (2) 'persistent learning agents' and 'knowledge engine learns' are aspirational—the code is stateful RAG, not t...
