Why Design Sketch on AI Image Tools

• Follows the sketch, not its imagination

  The instruction keeps the exact shape, proportions and design details you drew. It renders your object rather than a stock one.

• Name the material

  "Matte black aluminium", "white leather", "frosted glass": material and finish are the words that matter most.

• Iterate cheaply

  Five credits and under half a minute per render means you can try three finishes before lunch.

• Clean backgrounds

  Renders come on a soft studio backdrop by default. Ask for a cyclorama, a gradient or a lifestyle setting if you need one.

How to use Design Sketch

1. Step 1

   Upload the sketch

   Dark lines on a light background photograph best. Crop to the object.

2. Step 2

   Say what it is

   "Matte black wireless speaker, studio product shot". Add material and finish.

3. Step 3

   Render and refine

   Change one word, material or backdrop, and run again.

Get a better result

A few choices before you upload change the output more than any setting on this page.

• Dark lines on light paper

  The model reads your outline as the shape to render. Faint pencil on a shadowed page reads as noise.

• Crop to the object

  Cut out the rest of the page, your hand and the desk. Everything else competes for attention with the product.

• Name the material, not just the object

  “Matte black aluminium”, “frosted glass”, “white leather”. Material and finish change the render more than any other word.
