Cognee review
Graph-based agent memory with cloud or self-hosted deployment and usage pricing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cognee is an open-source memory engine and knowledge-graph platform for developers building AI agents and other AI applications. It ingests text, documents, and structured data, then processes them into graphs with entities, relationships, and embeddings. Agents can share graph memory across sessions, while search supports natural-language and structured queries. Teams can run the open-source engine locally or on their own infrastructure, or use Cognee Cloud for managed hosting and configurable graphs, prompts, and ontologies.
The Free plan costs $0 per month and includes 1M tokens, one workspace, unlimited users, unlimited API calls, and no card requirement. Standard uses usage billing at $1 per 1M tokens processed and adds data-source integrations, code indexing, and in-app support; additional workspaces cost $5 each per month. Enterprise adds BYOC deployment, a dedicated support engineer, a support SLA, and personalization per user and agent. This structure suits teams that want to start without a subscription, while token volume and workspace needs should guide budgeting.
Cognee connects with Slack, Notion, Linear, Google Drive, Claude Code, Codex, and MCP, and exposes web, API, and self-hosted deployment options. Its standout breadth is search: graph completion, chunk retrieval, temporal search, deletion of data items or datasets, and custom graph structures support varied agent-memory designs. Support is available through email, community resources, and documentation. Choose Cognee when shared, graph-based memory and deployment control matter; teams seeking a narrowly scoped key-value memory layer may prefer a simpler tool.
