Institutional memory for the agentic era.
Cortex turns your organization's documents into a living knowledge graph that every agent, app, and teammate can read, write, and reason over — so your collective knowledge compounds instead of walking out the door. Works with any model and harness.
All the intelligence.
None of your context.
Every agent in your organization has the world's knowledge and none of yours. The models are brilliant — they just have no idea who your customers are, what your team decided last quarter, or how your product actually works. Without shared institutional memory, 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.
Nextcloud Sync
Your Nextcloud folders, always in the graph
Pick folders in your Nextcloud and Cortex keeps them in sync — new and edited files flow into your knowledge graph on a schedule, fully automatic, even with the browser closed. Edited files update their existing entry instead of piling up duplicates.
Dropbox Sync
Selected Dropbox folders, synced on a schedule
Connect your Dropbox account in a minute — no app secret, no server setup — choose folders, and Cortex tracks exactly what changed through Dropbox's own change feed. New and updated documents land in your knowledge graph automatically.
Google Drive Sync
Share a folder, and it's in the graph
No OAuth consent screens, no app verification: your instance gets its own service account, and anyone — Workspace or personal Gmail — simply shares Drive folders with its email address, like sharing with a colleague. Regular files sync as-is; Docs, Sheets, and Slides arrive as PDFs.
OneDrive Sync
Your OneDrive folders, tracked by change feed
Connect with a simple device code — no client secret, no redirect servers — and Microsoft Graph's own change feed tells Cortex exactly what changed. New and edited files land in your knowledge graph on a schedule; updated files replace their previous version.

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,
every institution
Whether you're building agent infrastructure, running a company, or curating a community's shared knowledge, Cortex meets you where you are.
Make organizational memory survive beyond tenure
You want your teams faster, your customers better served, and your institutional knowledge to outlive the people who carry it — and be there the moment any agent, app, or teammate needs 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
- Provision an account for every employee in the companion Cortex Chat app
- 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.
Turn a community's collective knowledge into shared memory
DAOs, open-source projects, and member organizations run on knowledge scattered across Discord, forums, docs, and people's heads. Cortex gives your community one curated graph its members — and their agents — can actually draw on.
- Curate contributions into one growing, canonical knowledge graph
- Give members their own accounts in the companion Cortex Chat app
- Scope collections so groups see exactly the knowledge meant for them
- Every member's agent answers with the community's context, not guesses
- Grows with every source added — web pages, repos, and more
New members get up to speed from day one, and the knowledge outlasts any single contributor.
The memory backend you build against once
You've tried vector stores, RAG pipelines, and agent frameworks — and rebuilt from scratch every time a better model drops. 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.
Set it up once.
Serve everyone.
A single Cortex instance is shared infrastructure for as many people as you need. Give your whole team accounts in the companion chat app, plug it into the agents everyone already runs, or embed it in the products you ship to customers — all reading and writing one growing knowledge graph any agent or app in your organization can draw on.
Give your whole team accounts
Cortex Chat is a companion multi-user chat app for your instance. As an admin, you provision an account for every employee — each person gets their own login and their conversations are saved to their history, all grounded in the same company knowledge graph. No agent to build, no code to write: your team is asking questions on day one.
One admin, an account for everyone.
Enrich the agents they already run
Wire Cortex into the personal agents your team already uses — Claude Code, Cursor, Hermes, or your own. Drop in the Cortex skill and every reply comes back enriched with your company’s context, not just what the model learned from the internet. One graph feeds every agent at once.
Every agent reads and writes the same memory.
Embed it in the product you ship
Already serving a B2C customer base? Integrate Cortex into the applications you sell. The 60+ REST APIs let you put grounded, cited answers straight inside your existing product, so your own customers get your organization’s knowledge without ever leaving your app.
Your knowledge graph, inside your product.
One graph underneath all three. Whether someone opens the chat, fires up their own agent, or is a customer inside your product, they're drawing on the same living knowledge graph — and collections and granular API key permissions keep every audience scoped to exactly what it should see.
Start for Free and explore the intelligence ecosystem. As your agents and knowledge systems grow, simple monthly plans scale your storage, apps, and queries right up to production.
Everything your agents need
to remember your world
From document ingestion to agent-ready retrieval, Cortex handles the entire knowledge pipeline.
Knowledge Graph
Automatically extract entities and relationships from your documents. Build a traversable knowledge graph your agents can reason over — no manual work required.
Conversation Memory
Every conversation gets a durable memory — curated summaries, facts, open questions, and cited sources that carry across sessions, so your agent compounds what it learns instead of starting cold.
Living Sources
Pull in web pages and entire Git repositories — code, docs, and wikis — and keep them in sync as they change. Connected repos are bidirectional: your agent can read them and open pull requests.
Skills Hub
Install skills built on the agentskills.io open standard to extend retrieval — and let your agent take real actions on external APIs. Plain-text SKILL.md files, configured in seconds.
API-First
60+ REST endpoints with full OpenAPI documentation. Connect any agent, any framework, any model.
Ask AI
Natural-language Q&A with source citations, streaming responses, and multi-step deep research across your entire knowledge base — for humans and agents alike.
