> Your Library is where Chief keeps everything you add to a project: uploaded files, recordings, saved chat answers, and web pages.

## Your knowledge, in one place

Your **Library** is where Chief keeps everything you add to a project: [uploaded files](/help/your-knowledge-library/uploading-files-supported-file-types), [recordings](/help/your-knowledge-library/recording-audio-directly-into-chief), [saved chat answers](/help/your-knowledge-library/saving-a-chat-answer-back-to-your-library), and [web pages](/help/your-knowledge-library/adding-web-pages-urls-to-your-library). Once something is in your Library, [Chief can read it and use it to answer your questions](/help/your-knowledge-library/how-chief-uses-your-files-to-answer-questions), so the responses you get are grounded in your own material instead of generic information.

Each project has its own Library. The files you add to one project stay with that project, which keeps unrelated work separated and your answers focused.

## What you can keep here

* **Files** you upload (documents, PDFs, spreadsheets, images, audio, and more).
* **Recordings** you capture directly in Chief.
* **Web pages** you add by URL.

## What Chief does with it

When a file finishes processing, Chief understands its contents and can pull from it during a chat, on its own or alongside the rest of your knowledge. You can also organize your Library with [Labels](/help/labels/tagging-files-filtering-by-label) and [Collections](/help/collections/what-are-collections), and browse what Chief learned through [Concepts](/help/concepts/what-are-concepts).

<Note>
  ℹ️ **Good to Know:** A file is only usable in chat once it finishes processing. You can keep working while it processes, and Chief will mark it ready when it is.

## FAQ

<AccordionGroup>
  <Accordion title="Is my Library shared with other projects?">
    No. Each project has its own Library. If you want a file in another project, move or copy it there.
  </Accordion>

  <Accordion title="I added a file but Chief is not using it. Why?">
    The file may still be processing, or it may have failed to process. Open the file to check its status. If it shows an error such as running out of credits, resolve that and try again.
