Generate, review, and download a suitable result.
Match the art to its placement
Different placements need different composition, so say where the image will appear.
Input Constraints
- Describe the intended placement, such as a thumbnail or background
- Keep thumbnails high contrast with a clear subject
- Keep backgrounds subtle so overlays stay readable
- Avoid heavy text in the generated image
Practical Tips
- Mention the aspect ratio of the placement
- Use strong contrast for small thumbnails
- Keep one consistent palette across the channel
- Review art at the size it will actually appear
Privacy
- Do not upload personal or sensitive material unless you have permission to use it.
Usage Rights
- Confirm that you have the rights needed for the inputs and intended use of the result.
Prompt recipes
Copy a structure, then adjust the subject, lighting, camera, and output details for your own result.
High-contrast gaming thumbnail
A gaming thumbnail with a surprised gamer wearing headphones, explosive colorful background with bold shapes, high contrast, bright reds and yellows
Clear subject, explosive background, and high contrast make the thumbnail stand out in a small preview.
Tech review thumbnail
A tech product centered on a clean gradient background, dramatic side lighting, bold blue and white color scheme, minimalist composition
Centering the product and using a simple gradient keep the focus clear for small thumbnail sizes.
Tutorial intro background
A soft gradient background from teal to navy with faint geometric grid lines, subtle and calm for text overlays
Low-key backgrounds with soft gradients and faint patterns keep text readable without distraction.
Vlog channel banner
A bright outdoor landscape with a wide sky, warm sunset tones, space at the center for text, cheerful travel vibe
Describing the mood and leaving center space helps the image work as a banner with overlaid branding.
Dramatic cinematic intro
A cinematic intro scene with dark moody clouds, glowing light rays breaking through, dramatic atmosphere, deep blues and oranges
Cinematic lighting and a dramatic mood create an engaging visual for video intros.

Limitations to know before generating
- Text within generated images often renders imperfectly and should be added manually in an editor.
- Thumbnails must be reviewed at small sizes to ensure the subject remains clear.
- Backgrounds with too much detail or contrast can make overlays hard to read.
- Consistent branding requires repeating the same palette and style keywords across all assets.
- Always test generated art in the actual placement context before publishing.
