The memory layer your agents are missing.
Cortex is the memory layer for AI agents — a shared knowledge graph your agent can read, write, and reason over to genuinely understand your product's world. Integrates with any model and harness.
All the intelligence.
None of your context.
Your agent has the world's knowledge and none of yours. The model is brilliant — it just has no idea who your customers are, what your team decided last quarter, or how your product actually works. Without a shared memory layer, that gap shows up the same three ways, every single time.
Cold start, every time
Every tool call begins from zero. Your agent re-derives the same context on each run because nothing it learned last time was written anywhere it can reach again.
No memory between sessions
Each conversation forgets the last. Decisions, preferences, and hard-won context evaporate the moment the window closes — so your agent never compounds what it knows.
Retrieval is a gamble
Without a structured graph, every lookup is a coin flip on a vector DB you didn’t want to run — close-enough chunks, no real understanding of how things actually connect.
The fix isn't a smarter model — it's a memory layer. A shared knowledge graph your agents read, write, and reason over, so what's learned once stays learned.
Agents tend to forget. Cortex is how your organization remembers.
Every app deepens
the knowledge graph
The knowledge that matters to your organization doesn't only live in uploaded documents — it lives in every channel where your team thinks, talks, and creates. Each app is a new ingest vector: another channel through which your organization's knowledge flows automatically into the graph.
Web Crawler
Crawl any website into your graph
Point Cortex at any website or sitemap. It crawls every page, extracts content, and ingests it into your knowledge graph. Keep your graph in sync with the web.
Chat Interface
Talk to your knowledge graph
A lightweight, responsive chat UI that connects to your Cortex instance via a read-only API key. Supports deep research mode, local storage for conversation history, and works on any device.
GitHub Connector
Sync your repos into the knowledge graph
Connect GitHub, GitLab, or Gitea repositories as a living knowledge source. Cortex ingests your code, docs, and wikis and keeps the graph in sync as files change — and your research agent can act back on the repo by opening pull requests.
Youtube Importer
Turn any channel into searchable knowledge
Paste a YouTube channel URL and Cortex transcribes every video, converts them to structured markdown, and feeds them into your knowledge graph via API. Hours of video become queryable knowledge in minutes.

Start to compound
your knowledge
Your organizational knowledge accumulates value over time — entity relationships, community clusters, cross-document connections. The longer you use Cortex, the more your knowledge graph reflects your specific organizational reality.
First insight — the moment the graph knows enough about your organization that an agent gives you an answer you couldn't have gotten from a generic model. That's the activation event that converts trial to retention.
More knowledge ingested
Documents, apps, and integrations feed the graph continuously
Richer knowledge graph
Entity relationships, community clusters, and cross-document connections compound
Better agent answers
Agents give answers grounded in your organization, not the internet
More teams adopt Cortex
Value spreads as every team sees agents that actually know their world
More integrations connected
Apps and pipelines pull in knowledge from every channel
Cycle repeats
Skills flow
both ways
Cortex is built on the open skill standard — plain-text instruction files, no glue code, no runtime dependency. That makes the system bi-directional: pull other skills into Cortex to extend what it can do, or drop your Cortex skill into any other agent so it gains your organization's memory.
Take Cortex into any agent
Drop the Cortex skill file into any compatible agent and it instantly knows how to query your knowledge graph — no bespoke integration, no runtime dependency. Copy it in, and your agent gains organizational memory.
--- name: cortex description: > Query your organization's knowledge graph. Use when answering questions about internal processes, decisions, or institutional context. --- # Cortex Skill Your organization's knowledge lives in Cortex — a living knowledge graph built from your documents, channels, and team activity. ## When to use this skill - Any question about internal policy or process - Context about past decisions or projects - Entity lookups: people, teams, products, clients
Works with
Bring any skill into Cortex
Each skill teaches Cortex a new capability — legal review, compliance checks, data analysis. Install from skills.sh — the open registry with thousands of community-built skills — or author your own in minutes. Skills load on demand, so there's no bloat.
--- name: legal-review description: > Review documents for compliance risks, flag regulatory concerns, and suggest remediation steps. --- # Legal Review Skill ## When to use this skill - Contract review and risk assessment - Regulatory compliance checks - Policy document auditing ## Capabilities - Flag non-standard clauses - Check against regulatory frameworks
One open format, both directions. Skills are portable, version-controlled, and auditable — plain text with no runtime dependency. Extend Cortex with the wider skill ecosystem, and extend any agent with Cortex. Zero lock-in, either way.
From documents to intelligence
in four simple steps
Upload Documents
Drag and drop PDFs, Word docs, markdown, or text files. Cortex extracts text, chunks content, and generates embeddings automatically.
Build Knowledge Graph
GraphRAG extracts entities, relationships, and concepts. Your documents become a connected, traversable knowledge graph in Neo4j.
Query & Ask
Search with hybrid retrieval or ask questions in natural language. Get accurate answers with source citations in milliseconds.
Launch Apps
Browse the app library and launch integrations that extend your knowledge graph. Ingest from YouTube, the web, and more — or request a custom app built for your team.
One platform,
two entry points
Whether you're building agent infrastructure or deploying knowledge across teams, Cortex meets you where you are.
The memory backend you build against once
You've tried vector stores, built RAG pipelines, wired up agent frameworks. You know the problem: your retrieval layer is fragile, your memory doesn't persist across framework migrations, and every time a better model drops, you're rebuilding from scratch. Memory persists. Infrastructure doesn't.
- 60+ REST API endpoints with full OpenAPI docs
- Hybrid search: vector, keyword, and graph traversal in a single call
- Collections for per-agent, per-customer, per-use-case namespacing
- Framework-agnostic — LangChain, CrewAI, AutoGen, or your own stack
- Your knowledge graph persists independent of whichever framework you run today
When the next agent framework drops next month — and it will — you connect your existing Cortex instance to the new system in an afternoon.
Make organizational memory survive beyond tenure
You're not building AI infrastructure. You're trying to make your teams faster, your customers better served, and your institutional knowledge survive beyond the people who carry it.
- Managed knowledge graph with zero operational overhead
- Upload documents, run the pipeline, agents know your organization
- When a senior engineer leaves, their knowledge stays
- Multi-tenant collections for teams, clients, and projects
- Admin dashboard with visibility, control, and API key management
When regulations change, you update one document and every agent reflects the change immediately.
