About Cognee
Cognee is an open-source memory platform designed for AI agents that unifies vector search, knowledge graphs, and relational storage into one engine. It transforms data into connected, queryable memory that agents can recall across sessions and tasks. The platform ingests data from various sources, builds knowledge graphs with automatically generated or custom data models, and stores them across multiple layers to enable agents to retrieve connected context rather than just similar chunks. Cognee supports deployment options including cloud-hosted, self-hosted, and fully air-gapped infrastructure. It integrates with popular agent frameworks and tools, and helps teams build agent memory systems, GraphRAG pipelines, semantic search, document intelligence, and customer support agents that require persistent context.

FAQ
- What is cognee?
- Cognee is an open-source memory platform for AI agents that unifies vector search, knowledge graphs, and relational storage into one engine, turning data into connected, queryable memory that agents can recall across sessions.
- How is cognee different from a vector database or basic RAG?
- A vector database retrieves similar chunks. Cognee combines vectors with graph relationships, generated data models, and memory operations so agents can retrieve connected context and reason across sources.
- Which agents and frameworks does cognee integrate with?
- Cognee works with Claude Code, Cursor, Codex, LangGraph, n8n, CrewAI, the OpenAI Agents SDK, and Google ADK, plus an MCP server for any MCP-compatible client.
- Does cognee support multiple users, tenants, or workspaces?
- Yes. Cognee Cloud is multi-tenant with isolated workspaces and per-session memory, allowing you to serve many users or customers from one deployment.
- How does pricing work?
- Cognee Cloud uses usage-based pricing: a free tier with 1M tokens and one workspace, then $1.00 per 1M tokens on the Standard plan with extra workspaces at $5/month each. Enterprise adds dedicated support, SLAs, and bring-your-own-cloud. The open-source engine is free to self-host.
