Cognee

Cognee is an open-source AI memory platform for AI agents. It gives agents persistent long-term memory across sessions by ingesting data and building a self-hosted knowledge graph, so agents can recall and use context beyond a single interaction.

Cognee combines vector embeddings, graph reasoning, and ontology generation grounded in cognitive science. Documents become searchable by meaning and connected by relationships that evolve with the knowledge base. Agents can use session memory, graph-backed recall, auto-routing across search strategies, and dataset deletion.

Cognee runs locally, self-hosted, in Docker, on-prem, or on Cognee Cloud. It installs as a Python package with pip, poetry, uv, or another Python package manager, and has plugins for OpenClaw and Claude Code. Research from Markovic et al. covers optimizing knowledge graph interfaces for LLM reasoning.
