The job

Standing portraits often sit on a blank fill. This page swaps the background while keeping the same cast and art style, so the scene can match the rest of your chapter.

How it works

1. Upload a PNG or JPG still. This is the visual reference.
2. Choose whether the result should keep characters or be an empty environment plate.
3. Click Generate prompt (or write your own), pick art style, model, and image size, then generate.
4. Logged-in users get a daily free quota; extra runs use credits.

Where it fits in the workflow

Use this tool when the character is already drawn and you only need the scene. For full pages, open the chapter in Create so the new background stays locked to the same cast and story.

Honest limits

AI still misses faces, outfits, and panel continuity. If the output drifts, regenerate or edit inside the chapter instead of stacking disconnected images.

Example: Before & After

Background prompt：
A young man with spiked platinum blonde hair wearing a purple and charcoal tactical jacket stands in the center of a dense autumn forest. The environment is filled with towering maple trees sporting vibrant orange, gold, and amber leaves that create a glowing canopy overhead. A narrow, winding dirt path disappears into the soft golden mist of the background, heavily carpeted in fallen red and yellow foliage. Bright, diffused afternoon sunlight pierces through the vertical tree trunks, creating long, soft shadows and shimmering highlights across the textured bark. The air is clear and still, emphasizing the rich, warm color palette of the woods. The man remains exactly as he appears, his confident pose unchanged amidst the vast scale of the sun-drenched, seasonal wilderness.

Tips for better results

• Name the location, time of day, weather, and a few landmark objects.
• If you keep characters, say so and keep the prompt focused on the environment.
• If you want an empty plate, the model is instructed not to draw people.
• 9:16 is the default vertical panel frame; switch to 16:9 for a wide establishing shot.

Why creators use it

This page is a free AI character-background tool that reuses the same styles and models as Tab Story portraits, so the scene can match the cast.
