"LLMs know about everything public, but what if it could also know what's going on in our team? I want an AI coworker, not an AI new hire."
Onyx is the knowledge/context layer for your team and AI agents.
Onyx connects to your application to index and surface knowledge from 50+ applications while protecting your data sovereignty through flexible self-hosted deployments.
Beyond search, Onyx enables LLMs with advanced features like web search, sandboxes, skills, and more.
Tip
Deploy with a single command:
curl -fsSL https://onyx.app/install_onyx.sh | bash
Onyx creates a representation of knowledge across all connected sources. It pulls data along with metadata, permissions, etc. and ingests it so that the information is easily accessible for downstream use cases.
Compared to MCP based searches and index-free approaches, Onyx provides a more reliable, low latency, and low cost context for any given query whether it's a simple keyword query or a complex research task.
Instead of an agent coordinating and iteratively searching dozens of MCP and burning many thousands of tokens, Onyx fetches the context across its internal representation instantly and filters down to only the most relevant ground truth documents.
