The memory layer your agents are missing.
Cortex is a knowledge graph for AI agents. Drop in an MCP server or our SDK and your agent can read, write, and reason over a shared graph of your product's world — across Claude, OpenAI, and open-weight models. Free to start. No vector DB to babysit.
Your agent has the world's knowledge and none of yours. Without a shared graph, every tool call starts from zero, every conversation forgets the last one, and every retrieval is a coin flip on a vector DB you didn't want to run.
pip install cortex-sdk # or use the MCP servercortex.ingest("./docs") # entity extraction, graph build, all of itcortex.ask("what changed?") # hybrid search + graph traversal in one call- MCP server out of the box — plugs into Claude Desktop, Cursor, your custom agent
- Free tier sized for real building: 3 apps, 50K events, 7-day warm window
- The Cortex Apps marketplace turns every channel (YouTube, GitHub, Slack, your custom source) into ingest
- Your graph is portable. Switch frameworks; keep your memory.
Free forever for solo builders. Pro at $49 when you ship to users. Business when your users want SSO.

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.
YouTube Channel 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.
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.
Research Dashboard
Visualize your knowledge graph
A visual interface for exploring entities, relationships, and clusters in your graph. Map connections, spot patterns, and navigate your knowledge spatially.
Need something custom?
Describe the app you need, receive a quote, and we build it for your team. Same seamless payment flow as premium apps.
Teach your harness
about your organization
Cortex ships as a skill — a plain-text instruction file your AI harness can load. Drop it into OpenClaw, Hermes Agent, Claude Code, or any harness that speaks the skill protocol, and your agent gains immediate access to your organization's knowledge graph.
One file, any harness
Drop the Cortex skill into any compatible AI harness. Your agent instantly understands how to query your knowledge graph — no bespoke integration required.
Teach, don't rebuild
Skills are living instructions. As Cortex evolves, the skill evolves. Your agents always know the latest API surface, retrieval patterns, and query capabilities.
Zero-config activation
No SDKs to install. No adapters to wire up. A skill file is plain text — readable, auditable, and forkable. Copy it in, and your agent gains organizational memory.
Compatible harnesses
--- 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 - Cross-document synthesis and relationship queries ## Query POST /api/v1/query { "q": "your natural-language question" }
The skill protocol is open. Any harness that can load a markdown skill file gains access to Cortex. If your preferred harness isn't listed, copy the skill file in — it'll work. The format is intentionally portable: plain text, no runtime dependency, no SDK.
Any skill extends
your retrieval pipeline
Cortex implements the agentskills.io open standard. Skills are plain-text instruction files that teach the retrieval engine new capabilities — domain expertise, workflow automation, custom data analysis. Install a skill, and every agent querying your Cortex gains that capability instantly.
Open standard, infinite reach
Skills follow the agentskills.io format — a plain-text instruction file that teaches your Cortex new capabilities. Build once, use everywhere.
Capabilities on demand
Each skill teaches Cortex a new capability: legal review, data pipeline analysis, compliance checks, code review. Skills load on demand — no bloat, no wasted context.
Install from skills.sh or build your own
Browse and install skills directly from skills.sh — the open registry with thousands of community-built capabilities. Or author your own in minutes. A SKILL.md file is all it takes.
Direct integration
The Skills Hub installs directly from skills.sh — the open registry with thousands of community-built skills. Browse, install, and start using new capabilities in seconds.
--- 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 - Generate compliance summaries
Skills are the new apps. Built on the open agentskills.io standard. Install from skills.sh, author your own, or both. Every skill is portable, version-controlled, and auditable — one format, one ecosystem, zero lock-in.
Knowledge that
compounds over time
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
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.
