# Knowledge Sources

## Source modes

Your assistant can search either:

* **Entire library** — searches all your uploaded files. New uploads are automatically included.
* **Specific files** — only searches the files you select.

## Selecting specific files

When you choose "Specific files":

1. Browse your library with search and filters
2. Check the files you want to include
3. Save your selection

**Tip:** Use "Entire library" if you want the assistant to always have access to your latest uploads. Use "Specific files" if the assistant should only know about certain documents.
