How do I write a good instruction or prompt for DecorAI?
Updated August 19, 2026
Short answer
Write one short, concrete sentence about what you want changed and what must stay. Name materials, colours and objects ("replace the grey sofa with a cream bouclé sectional, keep the wooden floor"), and avoid vague adjectives like "nice" or "better". You can write in your own language.
Prompts that work well
- "Keep the layout, replace the curtains with floor-length linen, add a large round jute rug"
- "Warm minimalist office, oak desk, black steel shelving, one large plant, no clutter"
- "Same kitchen, matte dark green cabinets, brass handles, white marble worktop"
- "Remove the radiator under the window and add built-in bench seating"
Prompts that disappoint
- "Make it look nice" — no direction for the AI to follow
- "Modern, rustic, industrial, coastal" — four competing styles in one request
- "Move the window two metres left" — structural moves are unreliable; the AI is not a CAD tool
- Very long paragraphs — the important instruction gets diluted; keep it under about three sentences

Designing a roomWhat do the design controls in DecorAI do?Design controls are optional toggles that steer the AI beyond style and colour. DecorAI has more than 30 of them across five groups — camera and photo, furniture and layout, lighting and atmosphere, architectural elements, and decor and details — and several compatible controls can be selected at once.TroubleshootingThe design is not what I asked for. What should I change?Change one thing at a time and be more concrete. Name the materials and colours you want in the free-text field, reduce the number of design controls to two or three, and make sure the style and the instructions are not pulling in opposite directions.Privacy, safety & content rulesWhat content is not allowed in DecorAI?DecorAI is built for rooms, buildings and outdoor spaces. Automated safety checks run on every upload and every written instruction, and they reject sexual, explicit or violent content, and photos whose subject is a person. People incidentally present in a space — or shown in framed photos, posters, artwork or on a screen — are normally fine.
