Cognee solves a common problem with AI agents: they forget. It gives agents memory that lasts across sessions, drawing on graph, vector and relational storage to recall what matters.

You can connect sources such as Slack, GitHub and Linear so agents know what your company knows. It works with tools like Claude Code, Codex and MCP, and can run self-hosted, in Docker, on-premises or on Cognee Cloud. The core is open source and popular on GitHub.
