使用场景
AI智能体的长期记忆
通过将交互存储在知识图谱中并按需检索相关上下文，为对话式智能体提供跨会话的持久回忆。
基于上下文的文档RAG
摄入文档和结构化数据，然后结合图关系和语义搜索，提供比仅限向量的RAG更丰富、更准确的检索。
减少LLM应用中的幻觉
将LLM响应建立在先前捕获的事实和关系之上，减少重复提示并随着时间的推移提高答案的可靠性。
用于自定义堆栈的自主托管记忆层
使用Python SDK将Cognee插入首选的LLM、向量存储和图数据库，提供自主托管或托管部署以实现完全控制。

Does the job
Pretty happy overall. Pluggable LLM and storage providers just works and helps reduce repetitive prompting and hallucinations. but no dealbreakers — I'd recommend it to a friend without hesitating.
Does the job
Pretty happy overall. Querying across past sessions and documents just works and combines graph and vector retrieval for richer context. but no dealbreakers — I'd recommend it to a friend without hesitating.
Years in this space
I've evaluated a lot of these over the years. What stands out here is self-hosted or managed deployment options — handled better than most — and combines graph and vector retrieval for richer context. Worth the time if this is your use case.
Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on knowledge graph based agent memory, and combines graph and vector retrieval for richer context caught me off guard. still, I'd recommend giving it a real trial.
Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on knowledge graph based agent memory, and open-source with a flexible Python SDK caught me off guard. Requires technical setup and infrastructure knowledge is why this isn't a perfect score, still, I'd recommend giving it a real trial.
问答
Does cognee support multiple users, tenants, or workspaces?
Yes. Cognee Cloud is multi-tenant with isolated workspaces and per-session memory, so you can serve many users or customers from one deployment.
Asked by Quentin Lefevre · Mar 15, 2026
How accurate is cognee?
cognee is state of the art on BEAM, the agent memory benchmark — outperforming the previously reported state of the art on long-term, multi-session recall (79% vs. 73.4% at 100k tokens, 67% vs. 64.1% at 10M), without building a custom architecture for the benchmark.
Asked by Mei-Ling Wong · Mar 9, 2026
Is cognee cost-effective at scale?
Yes. cognee is built to keep memory costs flat as data grows — in our benchmarks it processes the same workloads at a fraction of a baseline LLM approach's cost.
Asked by Henrik Dahl · Mar 5, 2026
Which databases and data sources does cognee support?
cognee connects to the data sources your team already uses — Slack, Notion, Google Drive, GitHub, Confluence, Jira, Dropbox, Amazon S3, Salesforce, and more. Under the hood it works with graph and vector backends including Kuzu, NetworkX, Neo4j, FalkorDB, LanceDB, Qdrant, Milvus, Weaviate, pgvector, and Redis, so you can match your existing infrastructure.
Asked by Celia Ramirez · Feb 28, 2026
Can I run cognee on my existing Postgres database?
Yes. cognee runs on Postgres with pgvector, so you can add agent memory to infrastructure you already operate, instead of standing up a new database.
