What it does
All text below is quoted directly from the project README.
Cognee is a free open-source AI memory platform that gives AI agents persistent long-term memory across sessions. Turn documents, code, and conversations into a self-hosted knowledge graph your agents can search and reuse.
Runs locally for free — no API key required. We rely on free small models that use your CPU.
When to use Cognee:
- Build a Company Brain. Bring documentation, conversations, tickets, code, and agent work into shared memory. Help your team and agents connect a decision to the discussion and implementation behind it.
- Give agents memory across runs. Retain project context, past decisions, fixes, and learned rules. Distill useful session lessons into durable knowledge that another session can retrieve.
- Ground agents in your domain. Structure memory around the entities and relationships your application needs, with custom data models and ontologies.
How Cognee works:
Cognee builds connected memory from different sources. Text becomes entities, relationships, and searchable chunks; code becomes a graph of symbols and dependencies. Session distillation curates accepted lessons into permanent memory.
remember: Store content or code in permanent memory, or in a session when a session ID is supplied.recall: Retrieve context and answers, using automatic routing or a chosen search strategy.improve: Enrich memory, apply feedback, and bridge session knowledge into the graph.forget: Remove a specific item or dataset.
Text ingestion, retrieval, and session storage work without an LLM. LLM-dependent improvement stages skip automatically.
