cognee

Why we included this project

Agents that lose context between turns are a familiar frustration, and cognee tackles it by acting as a self-hosted memory layer. It ingests documents, chats, and other sources, then builds a knowledge graph from them so agents can recall connected facts with citations in later sessions. Unlike a plain vector store, which only returns similar chunks, cognee combines vector, graph, and relational storage, letting an agent reason across related entities instead of just matching text. It ships an MCP server and first-party integrations for Claude Code, Cursor, LangGraph, CrewAI, and the OpenAI Agents SDK, so adding durable memory to tools you already use is mostly a matter of wiring it in. Support agents, internal copilots, and coding assistants that need to remember past decisions are the clearest fit.
