MixboardAI turns one prompt into a coherent mood board of 6–12 images, auto-arranged into a Frame. The quality of that first render depends almost entirely on how the prompt is written.
This tutorial collects the rules of thumb we've developed after making a few hundred boards ourselves.
The prompt formula
<subject>, <2–3 sensory adjectives>, <era or material>, <optional mood>
Good examples:
- Coastal living room, natural linen, reclaimed oak, Mediterranean, sun-bleached
- Cyberpunk poster art, neon, rain, Tokyo 2077, vaporwave palette
- Minimal wardrobe for autumn, camel, ivory, wool, 1990s Scandinavian
- Home office, warm walnut, brass fixtures, golden-hour light, quiet luxury
Bad examples:
- "Cool room" (too vague — the model will hedge)
- "Home office like [influencer name]" (brand collapse)
- "A lot of nice things in a beautiful space" (adjective soup)
Editing individual images
Auto-layout gives you six to twelve images in one shot. If one of them is wrong, don't re-generate the whole board — you'll lose the good images. Instead:
- Click the outlier once to select it.
- In the toolbar that appears, hit Regenerate (same prompt) or Edit (write a one-line refinement like "same subject, warmer light").
- The new image replaces the old one in place. The layout doesn't move.
Batch edits
Select multiple images (hold Shift, click to add) and use the floating Batch Edit toolbar. You can type things like:
- "Make all of these black and white"
- "Add a soft film grain"
- "Recolor to a warmer palette"
Each image is re-generated in parallel, preserving position.
