Prompting Guide

The art of prompting.

On the “Let AI Choose For Me” path, the Custom Instructions textarea lets you push the design in a specific direction. It's optional — but the right wording makes a big difference.

On “Choose My Furniture”? You don't need to write anything — pick your products from the catalog and the AI handles the rest. This guide is only for the AI-design path.

Custom instructions that worked.

Copy any of these into the textarea. Swap the style. Try it on your own room.

What works.

Three patterns make prompts go from generic to great.

Lead with one or two styles

Vague

Make my living room look nicer.

Specific

Modern Scandinavian living room. Light oak, white walls, single mustard accent.

Name the key pieces

Vague

Living room.

Specific

Sectional sofa, area rug, coffee table, floor lamp, soft side chair.

Say what to keep

Vague

Modern living room.

Specific

Modern living room. Keep the existing dark blue couch — design around it.

What to skip.

Four ways prompts go wrong.

  • Too much in one prompt. Pick one style and a color story. Generate, then swap.
  • Conflicting styles. “Maximalist Scandinavian Industrial” — pick one or a clean pairing.
  • Vague adjectives. “Cozy” alone says nothing. Name the materials that make it cozy.
  • Vague colors. “Warm” → “cream walls, walnut wood, caramel leather.”
