# Introduction

> The context layer for AI agents

## What is ContextOne?

ContextOne is a context layer for AI agents that supercharges AI assistants with instant access to documentation and context.

Imagine your AI assistant has instant access to all the knowledge it needs. That's what ContextOne provides.

We give AI assistants a massive knowledge base with:

* **Public docs** from popular tools and frameworks (React, Python, AWS, etc.) - updated daily.
* **Your private docs** - company internal docs, code repos, websites - secure and private
* **Semantic search** that understands meaning, not just keywords
* **Multi-version support** - query specific versions like React v17 or v18

No more explaining the same things over and over. Your AI gets smarter answers instantly.
