The problem

What should be remembered gets forgotten, disconnected, or silently incompl.

Your team can't find what the company already knows. Your coding agents relearn the same context every run. Your agents don't know the rules of your domain. Start wherever it hurts most.

A company brain

Docs, chats, tickets, code, and agent runs: one permission-aware brain your agents and your team can query.

Memory for agents

Agents that recall past work, decisions, and fixes instead of relearning them every run.

Explore the SDK →

Ontology

Auto-generated ontologies keep memory structured to your domain — entities, relationships, and rules, not loose text.

✓ 3 agents connected · company brain active · knowledge wiki synced

$await cognee.remember("relevant context for agent memory")

→ ontology-guide.md:38 · domain rules ground ambiguous terms

→ ai-memory-notes.md:112 · graph links facts across sessions

→ support-notes.md:19 · answer keeps citations attached

✓ relevant memories stored · citations preserved

$await cognee.recall("Which sources explain how ontologies improve agent memory?")

✓ search 40ms · answer assembled from relevant memories

$await cognee.improve({ feedback: "use citation 2 first" })

✓ feedback stored · recall weights updated for next run

“Almost 24 hours since I added cognee across Codex — I'm noticing faster agents and better accuracy.”

How we build

Your company builds a shared company brain for agents.

Give your agent durable memory

Install Cognee and connect it to Claude Code, Cursor, or any MCP client. Your agent keeps project context across sessions. No new infrastructure.

$ pip install cognee

Solo devs · Agent hackersRun the quickstart

1 dayConnect

Connect the data your agents should know

We connect your GitHub org, Slack, or Linear — plus warehouses, docs, and APIs — into one recallable memory layer. Add a source once, and every agent can search it.

$ cognee.add("github://your-org")

Ship agents that understand your domain

We deploy Cognee BYOC — in your own cloud — behind customer-facing agents, so they retrieve cited facts, follow domain rules, and improve from real usage.

From the field

“Cognee and the FDE team have been terrific for us. We launched the first memory system within 30 days. Our teacher panel gave it overwhelmingly positive feedback. It opened our eyes to what’s possible.”

Ling ZhangUniversity of Wyoming - Assistant Professor and IEP Project Lead

“We tried understanding the proximity and relationships of our users before, but SQLs got out of hand and embeddings were too sparse. With cognee, we managed to get a POC done in 2 days on 40,000 students from Bremen.”

Gregor WeberVP & Co-Founder, Knowunity

“SlideSpeak customers create slides from scratch over and over again. With cognee, we added memory, so users can create better slides from shared context and improve those slides over time.”

Kevin GoedeckeFounder & CEO, SlideSpeak

“Cognee helped us enrich the data for thousands of our customers and provide them with personalized support better suited to their needs. The cognee team built and deployed the entire solution within a month.”

Orr KowarskyCEO, Dynamo

“The team helped me build a custom knowledge base of building codes and regulations that I could upload, query, and keep updated as regulations changed.”

Marko LazicCEO, Luccid

“Cognee’s design allowed our team to implement AI memory capabilities on-prem without worrying about graph or vector database configuration. The accuracy of our information retrieval has significantly increased.”
