# Design desktop

> The working UI for Cortex Design is a separate desktop app. Chat and Code create canvases; you edit them here.

The Design working UI is a desktop app of its own. The web app creates and lists canvases when Chat or Code hosts one; editing frames, notes, options, and the Library drawer happens here.

## Install

<Steps>
  <Step title="Download">
    Desktop builds are published at [releases.cortex.foundation](https://releases.cortex.foundation). Pick the Design desktop app for your platform.
  </Step>

  <Step title="Sign in">
    Same account as the web app. Canvases are member objects.
  </Step>

  <Step title="Open a canvas">
    Your canvases follow your account. Boards hosted from Chat or Code are already listed.
  </Step>
</Steps>

## Work on a board

Edit frames and notes, lay out options side by side, and pull components, pages, and tokens from the Library drawer. Rename the board from **Untitled canvas** to something useful; the host binding to the originating Chat conversation or Code session stays.
