# Design library

> Components, pages, and tokens you reuse across canvases. Thumbnails are uploaded, not rendered on this site. Not the same object as Chat's file Library.

The Design library holds the reusable pieces of your visual work: **components** you place on frames, **pages** you build from them, and **tokens** — colours, spacing, type — that keep everything consistent. It lives in the Library drawer of a canvas in the Design desktop app and belongs to your signed-in account.

## Add an item

<Steps>
  <Step title="Open a canvas in the Design desktop app">
    See [Design desktop](/design/desktop).
  </Step>

  <Step title="Create a component, page, or token">
    From the Library drawer.
  </Step>

  <Step title="Add a thumbnail when you have one">
    Thumbnails are **uploaded**. Nothing on this site rasterises them for you.
  </Step>
</Steps>

## Two libraries

| Holds    | Components, pages, tokens                  | Files you uploaded and files the assistant produced |
| Lives in | The Library drawer of a canvas, on desktop | **Artifacts** in the web app sidebar                |
| Used by  | Frames on a Design canvas                  | Chat turns and projects                             |

Same word, different objects. Items in one do not appear in the other.
