# Brain Overview

> Give your agent knowledge with documents, URLs, and custom content

## What is Brain?

Brain is your agent's knowledge base. It's where you upload documents, add URLs, and write custom content that your agent can reference during conversations. When a caller asks a question, the agent searches the Brain for relevant information and uses it to give accurate, grounded answers.

Think of it as giving your agent a manual to read before every call.

## How it works

1. You create folders to organize your knowledge
2. You add content — documents (PDF, DOCX, TXT), URLs, or plain text
3. The content is processed and indexed for fast retrieval
4. During a conversation, the agent automatically searches the Brain when it needs information
5. Relevant content is injected into the conversation context so the agent can reference it

The agent doesn't hallucinate answers — it pulls from the actual content you've provided.

## Organizing with folders

Brain content is organized into folders. Each folder can contain multiple items (documents, URLs, or text). You can create folders for different topics:

* **Products** — Product specs, pricing, features
* **Policies** — Return policy, terms of service, privacy policy
* **FAQs** — Common questions and answers
* **Training** — Scripts, objection handling, call flows

## Use cases

* **Customer support** — Upload your help docs so the agent can answer product questions accurately
* **Sales** — Add product catalogs, pricing sheets, and competitor comparisons
* **Healthcare** — Upload procedure guides, insurance info, and scheduling policies
* **Real estate** — Add property listings, neighborhood info, and mortgage details
* **Legal** — Upload contract templates, compliance docs, and FAQ sheets

## Storage options

Brain content can be stored using Orova's default storage or your own custom storage (AWS S3, Azure Blob, Google Cloud Storage, or Cloudflare R2). Configure storage in **Settings → Integrations**.
