AI Image Generator From a Photo, Sketch, Drawing or Text: Which Input to Use

Four ways to start an AI image generator

Most people meet AI image generation through a text box. Text is only one of the inputs, and for rooms and buildings it's often the weakest. What you give the generator decides what it has to guess, and the guesses are where results go wrong.

• Text or prompt: describes style, material, colour and mood. Position and layout are left to chance.
• Photo: fixes the real room or building, its perspective, and its light.
• Sketch or scribble: fixes where things go, without needing a photo.
• Drawing or architecture sketch: fixes precise geometry, from a hand plan or CAD line view.

AI image generator from text or a prompt

A text prompt is the fastest start. 'Japandi living room, oak floor, warm evening light' returns a good-looking room in seconds. The catch is that the room is invented, so it won't match yours, and repeating the prompt gives a different layout each time.

Use text to explore a look before you commit to a layout. Keep prompts short and specific: material, colour, era, light.

AI image generator from a photo

Starting from a photo removes most of the guessing. The generator keeps the walls, windows and perspective, and changes only what you ask. Use this input when the result has to be about your own room or house.

A photo is also the starting point for AI image editing: brush over one object and only that area is regenerated. In CreateLevel the same upload supports a full restyle and a single-object change.

AI image generator from a sketch or scribble

A scribble is a rough layout drawn with a brush or a finger: a box for the sofa, a line for the window. Sketch to image tools read those shapes as positions and generate materials, light and detail on top. Scribble interior design AI is useful when the room doesn't exist yet, or when you want to test where furniture should go.

Keep the lines clean and skip shading, because the model reads pencil tone as real shadow.

AI image generator from a drawing or architecture sketch

A more careful drawing gives more control. An architecture sketch of a facade, a floor plan view or a line export from SketchUp or CAD sets openings, proportions and roof shapes precisely. Drawing to image edit tools then render the finish while respecting those lines.

For buildings, this is the reliable route from concept to a picture you can show a client. The exterior design guide covers how facade sketches render.

Combining inputs

The best results usually come from two inputs together. Let the drawing or photo fix the structure and the prompt describe the finish:

• Photo + prompt: redesign a real room in a chosen style.
• Photo + brush + prompt: change one object and keep the rest.
• Sketch + prompt: turn a layout idea into a finished-looking room.
• Architecture sketch + prompt: render a building concept with a specific material palette.

Limits to know about

An AI image generator produces a picture. It doesn't know real dimensions, structure or cost, so use the image to decide and to communicate, then confirm the details with a professional.
