Mantha
What is Mantha? The design intelligence that reads your room like a decorator.
Mantha looks at your photo the way a designer would: it finds the walls, the floor, the direction of the light and where the shadows fall. Then it changes only the surfaces you choose.
The room's layout, the window light and the shadows stay put. What changes is the style or the edit you describe, such as new paint, flooring or furniture, drawn in the right perspective so it looks like it was always there.
