How is Rendair AI different from Photoshop generative fill?
Photoshop generative fill adds or changes content inside a selected area of an image. Rendair is built for architecture. It creates complete renders from sketches, plans, elevations and 3D views, and its edit tools change materials, lighting, objects and regions while keeping the design. They work well together: create in Rendair, then retouch in Photoshop.

Generative fill is a general editing feature. Rendair is a tool made for architectural visualization. The difference is in what you start from and what you get.
What generative fill does
You select an area of an image and describe what should appear there. It is a good way to fix or add something inside a picture you already have.
What Rendair does
Rendair starts earlier. You give it a sketch, a floor plan, an elevation, a photo or a view of your 3D model, and it creates the whole render. It follows the geometry of your input, so the building stays your building.
Editing in Rendair
Rendair also has tools for changing an existing render:
- Change material, time of day, season or weather while the rest stays the same.
- Select and modify to change a chosen region.
- Remove object, Extend Image and Virtual Staging for cleaning up, widening or furnishing.
- Upscale and enhance to make the final image larger and sharper.
Using them together
Many designers create and edit in Rendair, then do final retouching or layout in Photoshop. The two fit together in one workflow.
