# Expand your project

> Add a mobile app, slide deck, and more to an existing project — all sharing the same backend.

⏰ *Estimated time: 5 minutes* · Follows from [Build your first app](/getting-started/quickstarts/ask-ai)

You've built a web app. Now turn it into more — add a mobile app, a slide deck, or anything else, all inside the same project. Everything shares the same data and backend, so you don't have to start over.

## Before you begin

You'll need an existing project on Replit — from a previous quickstart or any project you've created.

## Your project can do more than one thing

When you built your first app, you created a web app. But a single project on Replit isn't limited to one output. You can add a **Mobile App** that works on phones, a **slide deck** to present your idea, an **animated video**, and more — all living side by side in the same project.

These are called **artifacts**. Each artifact is its own publishable output, but they all share the same code and data behind the scenes. Build once, publish everywhere.

## Add a mobile app

<Steps>
  <Step title="Ask Agent to create a mobile version">
    Tell Agent what you want:

    ```
    Add a mobile version of this app
    ```

    You can also click the **+** button in the Preview panel to add a new artifact.

    <Frame>
      <video autoPlay muted loop playsInline src="https://cdn.replit.com/sanity/design_mobile_app_canvas.mp4" />
    </Frame>

    Agent builds a mobile app that shares the same backend as your web app — any data or logic you've already built carries over automatically.
  </Step>

  <Step title="Preview on a phone simulator">
    When Agent finishes, the Preview panel shows your mobile app running in a phone simulator. Tap around and test it just like you would on a real phone.
  </Step>

  <Step title="Switch between your apps">
    Use the dropdown in the **Preview panel** to switch between your web app and mobile app.

    <Frame>
      <video autoPlay muted loop playsInline src="https://cdn.replit.com/sanity/switch_artifacts.mp4" />
    </Frame>

    You can also ask Agent:

    ```
    Show me the web app
    ```
  </Step>
</Steps>

## Add even more to your project

Your project isn't limited to web and mobile apps. You can ask Agent to create other types of artifacts too:

* **Slide decks** — "Create a pitch deck for this app"
* **Animated videos** — "Make a short explainer video for this app"
* **Data visualizations** — "Build a dashboard showing usage stats"
* **Documents** — "Write a one-pager describing this app"

Each one becomes a new artifact in your project, shareable with its own URL.

## Publish your project

When you click **Publish**, all artifacts in your project go live together. Your web app, mobile app, and slide deck each get their own URL, and they stay connected through the same backend.
