Overview

About Cognee

Cognee is a memory layer for AI agents. You feed it documents, code or previous conversations, and it builds a knowledge graph alongside vector embeddings so an agent can pull the right context back on a later run instead of re-reading everything. The Python SDK is open source and can run entirely on your own machines, with an MCP server and integrations for Claude Code and Codex. Cognee Cloud is the managed version, adding Slack, Notion, Linear and Google Drive connectors and code indexing for repositories, billed per token processed. Enterprise customers get it deployed in their own cloud as a fixed-scope engagement. It is built by Topoteretes UG in Berlin.

Editorial verdict

Pros & cons of Cognee

high confidence

Cognee's bet is that plain vector search loses the relationships between facts, so it builds a graph on top and lets agents traverse it. Being open source means you can run the whole thing locally and pay only if you want the hosted version, which is the right shape for infrastructure. The catch is that graph construction costs tokens, so a large corpus is not free even at $1 per million, and you are wiring a library rather than clicking through a product.

Pros

  • Open-source Python SDK you can run entirely on your own machines
  • Builds a knowledge graph alongside embeddings instead of only vectors
  • MCP server plus integrations for Claude Code and Codex
  • Free tier and pay-per-token pricing rather than a seat licence

Cons

  • Ingesting a large corpus burns tokens, and per-million billing adds up on big re-indexes
  • It is a library first, so expect to write code rather than configure a dashboard
  • Workspaces are billed separately at 5 dollars each beyond the first

Best for

  • Developers building agents that need recall across sessions
  • Teams whose data has structure that flat embeddings lose
  • Anyone who wants to self-host the memory layer rather than rent it

Not for

  • Non-developers looking for a finished application
  • Projects happy with a plain vector store and a single retrieval hop

Watch out: The price is per million tokens processed, not a monthly subscription. Re-indexing a big repository is a billable event.
