What prompt should I write?
You can write your prompt using natural, everyday language — it doesn't need to be complex or technical. Start by asking the AI to extend or expand the image, then include the desired aspect ratio (like "9:16" or "1:1") or orientation (like "portrait" or "landscape").
Examples:
- Expand this image to landscape
- Extend this image to 1:1
- Expand this photo into a 9:16 portrait format
You can also add creative context if you want the AI to include specific elements:
- Expand this image to include a window on the right
- Extend this scene to landscape and add a plant in the corner
If you're not sure what to write, the built-in AI Assistant can help refine your prompt and suggest better phrasing based on your goal.
