The infrastructure behind
agents that actually know
Knowledge graphs, hybrid search, and a growing app ecosystem — everything your agents need to reason over what your organization actually knows.
TL;DR: Cortex provides six core capabilities for AI agent memory: a knowledge graph with automated GraphRAG, a Skills Hub built on the agentskills.io open standard, a growing app ecosystem for ingestion and workflows, an API-first architecture with 60+ REST endpoints, enterprise-grade security, and natural-language Ask AI with source citations.
Knowledge Graph & GraphRAG
Your organization's memory, structured for agents
Cortex extracts entities, relationships, and concepts from your documents automatically. The result is a living knowledge graph that agents can traverse to reason across your entire organization — not just retrieve similar text.
- Automatic entity extraction (people, orgs, concepts, locations)
- Relationship discovery between entities
- Semantic entity resolution (merge duplicates)
- Multi-hop graph traversal for deep context retrieval
- Community detection and summarization
Key Metrics
Skills Hub
Extend retrieval with the open standard
Cortex implements the agentskills.io open standard. Skills are lightweight instruction files that teach the retrieval engine new domain capabilities. Install a skill and every agent querying your Cortex gains that expertise instantly.
- agentskills.io open standard — supported by 30+ agent products
- Install skills to add domain expertise (legal, compliance, engineering)
- Author custom skills in minutes with SKILL.md files
- Progressive disclosure — skills load on demand, not upfront
- Version-controlled, auditable, portable
Key Metrics
App Ecosystem
A marketplace that deepens your graph
Browse a growing library of apps that plug into your knowledge graph. Source apps ingest knowledge from YouTube, the web, and more. Workflow apps unlock better interfaces and integrations. Every app you launch feeds the graph, and the graph gets smarter with every document.
- Source apps for YouTube, web crawling, and more
- Workflow apps for dashboards, exports, and integrations
- One-time payment to unlock premium apps via Stripe
- Request custom apps built for your team
- New apps added continuously
Key Metrics
API-First Architecture
Connect any agent, any framework, any model
60+ REST endpoints with full OpenAPI documentation. Integrate Cortex into any agent framework, build custom interfaces, or wire it into existing pipelines. When you switch stacks, the knowledge graph comes with you.
- 60+ REST API endpoints
- Full OpenAPI/Swagger documentation
- Webhook support for events
- Background task tracking
- Comprehensive error handling
Key Metrics
Enterprise Security
Agent infrastructure you can trust in production
Built-in prompt injection protection, granular API key permissions, audit logging, and secure session management. Deploy agent memory infrastructure with confidence.
- Prompt injection protection built-in
- API key authentication with roles
- Granular permissions (read, write, delete, admin)
- Key expiration and rotation
- Secure session management
Key Metrics
Ask AI
Natural language Q&A for humans and agents alike
Ask questions about your knowledge base and get accurate, cited answers. Streaming responses, multi-step agentic reasoning, and conversation history — ready for both human users and agent pipelines.
- Natural language question answering
- Source citations with every answer
- Streaming responses for real-time UX
- Agentic mode with multi-step reasoning
- Conversation history for context

Frequently asked questions
Technical details about Cortex capabilities.
GraphRAG combines knowledge graph traversal with retrieval-augmented generation. Cortex automatically extracts entities and relationships from your documents, builds a traversable graph, and uses graph structure — communities, clusters, and multi-hop paths — alongside vector search to retrieve richer, more accurate context for LLM responses.
