Frequently asked questions
Can I redesign a room from a photo?
Yes. Upload one photo of the room as the reference image and describe what should change; the model keeps the room structure where possible and applies the new style.
Do I need 3D software skills?
No. Describe the change in plain text or pick a template, and the render is generated for you.
Can I get a floor plan or material board?
Yes. The template library includes 30 floor plan templates and 20 material board templates you can run with your project details.
Is the output ready for contractors?
Treat renders as design direction, not construction documents. Dimensions, structure and specifications must be confirmed by a professional.
How much does a render cost?
Renders start at 2 credits per image on GPT Image 2; the exact total is shown before each generation.
