# Apps

> Build custom, interactive data experiences backed by governed data from your Cube semantic layer.

<Warning>
  Apps are currently in preview, and their capabilities and authoring experience may
  still change. Reach out to the [Cube support team](/admin/account-billing/support)
  to activate this feature for your account.
</Warning>

Apps let you go beyond a dashboard's grid of widgets. An app is a custom,
interactive interface with its own layout, components, and controls, powered by
live data from reports in a Cube workbook.

Use an app when you need a guided workflow, a custom visual presentation, or an
interactive data tool that does not fit a standard dashboard layout.

## Create an app with the Cube agent

Open a workbook, switch to **Dashboard Builder**, and describe the app you want in
the agent chat. Include the business question, the data you want to show, and how
people should interact with it. For example:

> Build a revenue performance app with headline metrics, a monthly trend chart,
> and a searchable status filter. Use the company's brand colors.

The agent creates the workbook reports, writes the app, and installs reusable
components for common elements such as charts, tables, KPI cards, tabs, and
searchable controls. Continue prompting the agent to adjust the layout, behavior,
or styling.

## Preview and edit the app

Use **Preview** to interact with the running app. Select **Code** to inspect or
edit its files directly. After making code changes, click **Run** to apply them
and refresh the preview.

App components are copied into the app's source, so you can customize their code
and styling for that specific experience.

## Governed data access

An app reads the results of reports in its workbook. Cube runs those reports using
the viewer's existing permissions and passes the results to the app. The app does
not receive credentials for your data source or Cube APIs, and it cannot query
your warehouse directly.

Apps run inside a sandboxed frame, isolated from the Cube interface. The app's
data access remains governed by the semantic model and the permissions already
configured in Cube.

## Preview limitations

During preview:

* Apps are created and viewed from the workbook's Dashboard Builder.
* Publishing, embedding, scheduled refreshes, and deliveries are not yet
  supported for Apps.
* Apps can read workbook report results but cannot write data back to a source.
* Available components and APIs may change as the feature develops.
