Cognee has no ongoing free tier; what it offers is a credit grant that runs out. Open-source memory engine that turns documents and data into a knowledge graph agents can query… Verified November 2026. Compare with 3 alternatives in AI / ML.
Subtypes in AI / ML: agent_memory — stores what an agent is told or learns (conversations, documents, user activity) and returns the relevant part to the agent on later calls; the stored unit is a memory or fact, not a vector the caller computed. We read that on 2026-10-09 from https://www.cognee.ai/, where it says: “Cognee gives your agents memory.” How we use this.
Cognee has no ongoing free tier; what it offers is a credit grant that runs out: Open-source memory engine that turns documents and data into a knowledge graph agents can query… It's stable — zero pricing changes recorded. Best for ai / ml workloads.
Open-source memory engine that turns documents and data into a knowledge graph agents can query. Cognee Cloud's Free plan is $0/month, labelled "Free forever", with no card required: 1 workspace, unlimited users and API calls, and 1M tokens included (Cognee's billing docs say 10M). Cognee does not say the tokens renew; when the balance runs out, uploads, graph processing and search are refused. Tokens beyond it cost $1.00 per 1M on every plan, and Standard adds workspaces at $5 a month each. The open-source engine (Apache 2.0) is free to self-host.
We read that on 2026-11-12 from https://www.cognee.ai/pricing, and our check recorded: the page names Cognee as "cognee" and states "$0" and "$1.00" and "$5".

No recorded pricing changes for Cognee. This is a good sign — stable pricing.
How Cognee compares against every one of the 3 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.
