Open source AI memory engine combining relational, vector and graph stores, with remember, recall, improve and forget operations, session memory, and Python, REST, CLI and MCP access.

Cognee, from Topoteretes UG in Berlin, is an open-source AI memory engine that turns documents, code and application data into persistent memory that agents and applications can store, query and improve over time. It combines three stores: a relational store for documents, chunks and their provenance, a vector store for semantic similarity, and a knowledge graph of entities and relationships, built by pipelines that ingest, extract and enrich data, with ontologies, a dataset-level context index and deduplication to keep the graph coherent.

The developer surface centers on four operations: remember, recall, improve and forget. Sessions give each user short-term memory for a conversation or agent run, session distillation turns guidance from a session into permanent lessons, and per-user preferences adjust retrieval. Recall routes across vector, graph and hybrid retrieval with provenance on answers. Cognee is reached through a Python API, a REST API, a CLI and an MCP server, integrates with LangGraph, CrewAI, the Claude Agent SDK, the OpenAI Agents SDK, Google ADK, n8n, Claude Code and Codex, and ingests from Slack, Notion, Linear, Google Drive and GitHub on paid plans.

Customers choose their LLM, embedding provider, vector store and graph store, and run Cognee locally, self-hosted with Docker or Kubernetes, in Cognee Cloud, or in their own cloud through an Enterprise engagement. Multi-user mode adds tenants, roles and access control lists with per-tenant databases; Cognee states it does not yet hold SOC 2 or ISO 27001. The cloud has a free tier with one workspace and a million tokens, a Standard plan at $1.00 per million tokens plus $5 per extra workspace, and Enterprise bring-your-own-cloud engagements.

Integrations

Memory native API (remember, recall, forget, improve) through Python and TypeScript SDKs, a CLI, and the Model Context Protocol. Native integrations with LangGraph, CrewAI, the Claude Agent SDK, the OpenAI Agents SDK, Google ADK, and n8n, ingesting from more than thirty data sources. Pluggable storage across Neo4j, Neptune, Qdrant, and pgvector.

In practice

Your agent forgets everything when a session ends. You add Cognee's remember and recall API, and it builds a persistent knowledge graph so the agent carries context, preferences, and decisions across sessions.

You need multi hop reasoning over connected documents, not flat chunks. Cognee's Cognify pipeline extracts entities and relationships into a graph, so retrieval traverses relationships instead of nearest neighbor lookups alone.

Regulated data cannot leave your infrastructure. You self host the open source engine on your own Neo4j and Qdrant, keep full data ownership, and still give every MCP agent one shared memory.

Integrations & Tool Calling Partial

Standard adds OAuth data source integrations for Slack, Notion, Linear and Google Drive, and a GitHub integration re-indexes repositories on push, all reading content into memory, while native integrations wire Cognee into LangGraph, CrewAI, the Claude Agent SDK, the OpenAI Agents SDK, Google ADK, n8n, Claude Code and Codex. These read into Cognee or connect it to agents. No read-write or actionable routes that let an agent act in outside systems are documented.

Workflow Orchestration Partial

Pipelines orchestrate Tasks into coordinated workflows with a typed runtime context, and developers can build custom tasks and pipelines; these sequence the steps that build and enrich memory. That is orchestration inside a single use case, memory processing, rather than control flow for the customer's agent workflows.

Knowledge Grounding & RAG Full

Documents, code and application data, including Slack, Notion, Linear, Google Drive and GitHub sources, are ingested into a relational store of documents, chunks and provenance, a vector store of embeddings and a knowledge graph of entities and relationships, which recall queries by vector, graph or hybrid retrieval with provenance on answers and an optional dataset-level context index. That gives the customer a maintained index and graph over its knowledge that persists and stays queryable.

Human Oversight & Guardrails Not documented

A feedback system lets users rate answers to improve memory, and the permission system controls who can read and write datasets, but no approval step, consent checkpoint, escalation rule or pause for a person's sign-off before an agent acts is documented.

Security, Identity & Governance Partial

Multi-user mode enforces authentication and dataset-scoped permissions through users, tenants, roles and access control lists, with each tenant's data in a dedicated database, and the larger enterprise engagements add SSO. Cognee states it does not currently hold SOC 2, ISO 27001 or an equivalent third-party certification.

Observability & Auditability Partial

Agent session traces record what a decorated agent function did on each call, including calls that raised errors, and can be recalled later; Cognee emits OpenTelemetry spans and logs to an OTLP endpoint such as Langfuse, writes structured logs, and visualizes memory provenance. The traces documented cover Cognee's own operations and the decorated call, not a step by step view of the agent's prompts, tool calls, retrieved knowledge and outputs.

Memory & State Persistence Full

Sessions are short-term memory scoped to a user and session ID, holding recent queries, responses and the context used to answer them; session distillation turns guidance stated in a session into permanent lessons that later recalls respect, per-user preferences adjust retrieval for each user and agent, and forget can reset memory-only state or delete one dataset without touching others. Each memory layer has a stated scope and a stated lifetime.

Deployment & Data Residency Full

Cognee runs as managed Cognee Cloud, as open-source software self-hosted with Docker Compose, a Helm chart for Kubernetes, EC2 or Coolify, fully locally with Ollama and embedded stores, or as an Enterprise deployment in the customer's own cloud.

Prebuilt Agents, Templates & Packs Not documented

Examples and guides for building agents on Cognee's memory layer are published, but no catalog or set of ready-made agents or templates a customer adopts is documented.

Triggers & Channel Coverage Not documented

Agents and applications call Cognee, a memory layer, through remember and recall, and no schedule, event or channel that starts an agent's work without a person or the calling application initiating it is documented.

Model Flexibility & Routing Full

The customer configures which LLM provider Cognee uses, from OpenAI, Azure OpenAI and Anthropic to local models through Ollama, and separately chooses the embedding provider, vector store and graph store. Model choice stays under the customer's control.

APIs, SDKs & MCP Extensibility Full

Cognee documents a REST API with an OpenAPI specification for datasets, ingestion, recall and activity, a Python API, a CLI and an MCP server for Cursor, Claude Code and other clients, and serve and push connect the SDK to Cognee Cloud or a remote instance. That is a stable API and SDK for Cognee's own platform.

Testing, Debugging & Optimization Not documented

Cognee publishes memory benchmarks for its own engine, which measure the vendor's product, and its documentation describes no evaluation harness, scored test cases or quality gate a customer runs against its own agent.

Browser & Computer Use Not documented

Web URL ingestion fetches page content with custom extraction rules to build memory, which is building the corpus rather than an agent operating a browser at run time, and no browser, desktop or computer control is documented.

What is public

The free tier, the Standard rate of $1.00 per million tokens plus $5 per extra workspace, the Enterprise engagement tiers and the free open-source self-host path are published.

Billing mechanics

Open source and free cloud tiers carry the engine at no vendor cost. Cloud Pro meters tokens processed at $2.50 per million. Enterprise runs in a private cloud with bring your own key so model and infrastructure costs stay on the customer's accounts.

Cost watchouts

Building memory spends LLM tokens at ingestion, billed per million tokens on Standard, and each extra workspace adds $5 a month; self-hosting moves the cost to the customer's own LLM keys and stores.

Variable cost rationale

Token based cloud pricing scales with ingestion and query volume, but the free tier and modest $2.50 per million rate keep growth predictable, and self hosting caps the vendor cost entirely.

Overage / add-ons

Cloud usage bills at $2.50 per 1 million tokens processed above the free allowance.

Sales call required

Mixed (some tiers require a call)

Free / trial

Free forever: 1 workspace and 1M tokens included, no card required; open source free to self host
