Cognee

Cognee is a platform and open-source tool for building persistent memory for LLMs, autonomous agents, and organizations. It lets users and developers capture structured knowledge graphs from documents, conversations, code, and tickets, and retrieve them for future queries—enabling organizational memory, agent recall across sessions, and domain grounding with custom ontologies. Designed for those building AI-powered agents, workflows, or company-wide knowledge bases, Cognee offers both local and managed deployments, integrations for various agent frameworks, and flexible API/SDK options.
