Image Generator

The Image Generator lets you create images for your prototypes using generative AI. You can access it from several places in the app:

• The Assets section (left sidebar)
• When setting an element cover
• When setting a component cover

The Image Generator follows the shared AI access requirements. Prompts entered in the Image Generator can contain up to 3,000 characters.

ℹ️ Each image generation costs 5 AI credits from your workspace's monthly allowance. See monthly AI credits by workspace plan.

AI settings

In your project settings (accessible from the top menu), you'll find an option for accessing the AI Settings.

1. Click the Settings cog and select AI Settings... from the dropdown.

2. Optionally add project-wide guidance for image generation:

   • Fill in the Image Generation Guidelines to define the art style rules for the images you generate. You can specify guidelines, preferred styles, or any other instructions you want applied to all image creations across the app.
   • Drag image assets from the Assets sidebar into Attached Style References to use them as visual guides for palette, mood, lighting, texture, and rendering style.

ℹ️ Attached style references are treated as style guides by default. They do not cause Arcweave to copy the specific characters, props, places, or compositions shown in those images unless you explicitly ask for that in your prompt.

ℹ️ If you add attached style references, you can mention them by name in your prompt to steer the generated result more precisely.

Use from the Assets section

1. Open the Assets tab in the left sidebar.
2. Click the Create asset button (image icon with a plus) in the top-right corner of the Assets panel, or right-click inside the Assets panel.
3. Select Generate asset...
4. Choose the image size:
   • Square: 1024 x 1024
   • Vertical: 1024 x 1536
   • Horizontal: 1536 x 1024
   • Custom: Enter a width and height. Each side must be a multiple of 16 pixels and at most 3,840 pixels, the image must contain between 655,360 and 8,294,400 pixels, and the longest side can be at most 3 times the shortest.
5. Optionally, check Transparent background (PNG).
6. Enter a prompt describing what you want to generate.
7. Click Generate.
8. After the image is generated, click Import in Asset List to add it to the project's Assets section.

ℹ️ To generate an image directly into an asset folder, right-click the folder (or click the + that appears when you hover over it) and select Generate asset...

Use from elements

Set covers

1. Right-click an element and choose Cover > Set cover.

2. Switch to the Generate tab.

2. Select AI > Auto-generate cover.

3. Your image will be created automatically in the horizontal size (1536 x 1024), imported into the Assets section, and set as the element cover.

ℹ️ The context used when auto-generating element covers is defined by the element's title and content, along with the AI Settings, including both your text guidelines and any attached style references.

Use from components

Set covers

1. Open the component.
2. Hover over the cover area and click Change cover in its top-right corner.
