# AI Effects

After your [AI Effect](https://app.simplebooth.com/ai-effects) has been [configured](/ai-effects/post-capture-ai-effects.md), it must be added to a layout within a [preset](https://app.simplebooth.com/presets) before it can be used by guests.

{% hint style="info" %}
If you generated the effect directly from within the Layout Designer, it is already applied to that specific layout.
{% endhint %}

#### How to Add an AI Effect to a Layout

Follow these steps to enable a saved effect for your event:

1. From your [preset list](https://app.simplebooth.com/presets), open the preset you want to customize.
2. In the **Layout** section of your settings, create a new layout or select an existing one.
3. In the [**Inspector**](/copy-of-halo-app/layout-designer/layout-designer-overview.md#inspector-panel), select **Choose** to browse your saved effects or the public library.
   * You can also generate a new AI Effect from the layout designer. 
4. Select the effect you want to use and save your changes.
5. Generate **Layout Previews**. These act as "thumbnails" shown to guests before they take their picture so they know what style to expect.

#### Layout Previews

Layout previews are essential for helping guests choose their preferred look during an event and reducing your credit usage.

* **Automatic Generation:** A layout preview may already be generated for you depending on how the AI effect was initially created.
* **Preflight Check:** If any previews are missing when you are ready to launch, the Simple Booth app will prompt you to generate them during the preflight check.

{% hint style="info" %}
Generating layout previews is optional but highly recommended. Providing a visual example ensures guests understand the transformation that will occur after their photo is captured and can help reduce unnecessary credit usage.
