# Using the builder dock

> Learn how to use the floating dock in the resume builder for zooming, page layout, sharing, exports, and AI assistance.

The builder dock is the floating toolbar at the bottom of the resume builder. It gives you quick access to preview controls, sharing, exports, and the AI assistant without leaving the resume canvas.

## Preview controls

Use the left side of the dock to control the preview.

| Control                  | What it does                                           |
| ------------------------ | ------------------------------------------------------ |
| **Zoom in**              | Increases the preview zoom.                            |
| **Zoom out**             | Decreases the preview zoom.                            |
| **Center view**          | Re-centers the resume preview in the canvas.           |
| **Toggle page stacking** | Switches between stacked pages and side-by-side pages. |

These controls only affect the editor preview. They do not change the exported PDF, DOCX, or JSON file.

## Open the AI assistant

Click the assistant button to open or close the **AI Resume Assistant**.

The assistant can propose targeted resume changes, such as rewriting a summary, tightening bullet points, adding metrics, or tailoring the resume to a job description. You review proposed changes before they are applied.

<Info>
  The assistant requires a tested and enabled AI provider. See
  [Using Artificial Intelligence](/guides/using-ai) for setup and [Using AI in the builder](/guides/using-ai-in-the-builder)
  for the builder workflow.
</Info>

## Copy the public URL

Click **Copy URL** to copy the resume's public link.

The URL is based on your username and the resume slug:

```txt theme={null}
https://rxresu.me/{username}/{slug}
```

<Warning>
  Copying the URL does not make the resume public by itself. To allow visitors to open the link, enable public access in
  the **Sharing** section of the right sidebar.
</Warning>

## Download files from the dock

The dock includes quick download buttons for:

* **JSON** for backups, imports, and structured data workflows;
* **DOCX** for editing in Microsoft Word or Google Docs;
* **PDF** for sharing, uploading, and printing.

These are the same export formats available in the right sidebar's **Export** section.

<Tip>
  Use the dock when you already know which file you need. Use the right sidebar's **Export** section when you want the
  format descriptions next to each button.
