## Knowledge Bases

Knowledge bases teach your agents about your specific content — products, documentation, policies, and more.

### Adding Knowledge

You can add content in several ways:

| Method | Best For |
|--------|----------|
| **PDF Upload** | Manuals, guides, documentation |
| **Web Crawl** | Websites, online docs, help centers |
| **Manual Text** | Policies, FAQs, specific information |

### How It Works

When you upload documents, Chatto:

1. Breaks the content into smaller chunks
2. Analyzes the meaning of each chunk
3. Stores them for fast retrieval
4. When someone chats with your agent, relevant chunks are found and used to answer

### Best Practices

- **Keep documents focused** — One topic per document works best
- **Use clear headings** — Helps the system understand structure
- **Update regularly** — Keep knowledge current
- **Test after uploading** — Chat with your agent to verify it learned correctly

### Supported Formats

- PDF documents
- Web pages (via URL)
- Plain text
- Excel spreadsheets
