常见问题
What does this tool do?
It generates a new AI background scene around your described subject, producing a professional-looking composite image. You describe both the subject and the desired new setting, and download the result.
Do I describe the subject in text or upload it?
You describe your subject and the new background in words, and the AI generates the full composite scene from that prompt. Be specific about the subject so it stays the focal point.
What kinds of backgrounds can I create?
Almost any — plain studio backdrops, outdoor scenes, gradients, lifestyle settings, seasonal themes, or branded environments. Describe lighting and mood for a more convincing blend.
What resolution and format is the output?
You receive a high-resolution composite image suitable for listings, ads, and social posts. Download and crop to a platform's required dimensions if needed.
How realistic is the result?
Results are strong for clear, well-described subjects, but the AI generates the whole scene rather than perfectly masking an existing photo, so lighting and edges can vary. Regenerate with more detail to improve realism.
Can I use the images commercially?
Yes, generated composites can be used for e-commerce, advertising, and marketing for personal or commercial purposes.
Are my prompts kept private?
Your description is processed to generate the image and is not posted to any public gallery. Save outputs you want to keep.
Is it free?
Yes — 5 generations per day free with no signup; Pro is $19/month for more volume.
