# 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>

## What each kind of item is for

| Item          | What it is                       | Reused by                              |
| ------------- | -------------------------------- | -------------------------------------- |
| **Component** | A piece you place on a frame     | Frames on any of your canvases         |
| **Page**      | A screen built from components   | The board you are working on           |
| **Token**     | A colour, spacing, or type value | Components and pages that reference it |

Tokens are the reason two frames can look like one product: change the value once and the components that reference it follow. They are values you maintain, not a theme the app picks for you.

## Two libraries

|          | Design library                             | [Chat Library](/chat/library)                       |
| -------- | ------------------------------------------ | --------------------------------------------------- |
| 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.

## Who can use it

Library items are member objects, like the canvases they sit on: a guest cannot create one, and another account's items are never listed. See [Accounts](/getting-started/accounts).

The drawer is on the desktop only. The web app lists canvases but has no Library drawer and no `/design` route — see [Design desktop](/design/desktop).
