Step-by-step: sketch to render

Step 1: Upload your sketch

Upload a photo or scan of your drawing. Crop out the desk, hands and paper edges.

Darken faint pencil lines with a pen or an editing app before uploading.

Step 2: Select the space type

Choose Interior, Exterior or Garden.

Step 3: Choose a design style

Click View All to browse 75+ styles and pick the one that matches your idea.

Step 4: Set the AI Intervention slider

Lower settings keep the render close to your sketch; higher settings let the AI make bolder design choices.

Step 5: Add instructions (optional)

Open Additional Instructions to name materials, colors or features, such as “stone facade, black window frames, wooden deck”.

Step 6: Generate 1–4 renders

Choose the number of designs (one credit each) and click Generate New Designs.

Step 7: Sharpen with HD

Use the HD button to improve textures and realism, then download.

Tips for faithful renders

  • Draw in perspective, not just a flat plan, for room and facade renders.
  • Label key materials on the sketch or in the instructions.
  • Keep AI Intervention low when proportions matter.
  • Have a floor plan instead? Use 2D to 3D floor plan.
