</Frame>

> `In Settings > Knowledge base`, Click `Add` to add document files and web pages to your knowledge base.

<Info>
  When adding web pages, only the specific URL page you input will be used as the knowledge base. Other pages from the same domain or linked pages are not included.
</Info>

<Note>
  Adding content to the knowledge base consumes credits due to OCR processing, database management, and indexing operations.
</Note>
