デザインスタイルを特定し再現する
I love this style: [describe what you’ve seen or paste a photo] My room currently looks like: [description or photo] My budget: [amount] Tell me: 1. What design style this actually is (with the proper name) 2. The 5 defining elements of this style 3. Which 3 changes would get my room closest to this look 4. What to absolutely avoid (common mistakes with this style) 5. One “cheater” piece that instantly makes a room feel like this style
プロのコツ
インスピレーション写真がある場合は、アップロードするだけでなく詳細に描写しましょう。AIは全体的な雰囲気ではなく、特定の要素を大切にしていることを知ると、より良いスタイルマッチングを提供します。

Gemini
Best for photo-based redesigns. Upload a room photo and Gemini reads the layout, identifies furniture, and works around fixed elements. Spatial awareness is noticeably ahead.

Best for mockups and product recs. Generates images showing your redesign and knows real products at real prices. Tends to over-suggest — tell it exactly what to leave alone.
結果元: GPT-4o · テスト済み Feb 12, 2026Claude
Best for design reasoning and color theory. Gives the most thoughtful explanations of why things work. Great for palettes and style mixing. No image generation.
結果元: Claude 3.5 Sonnet · テスト済み Feb 12, 2026Grok
Best for bold, trend-forward design suggestions and cutting through indecision with direct style recommendations. Strong awareness of current design trends and unconventional pairings. Less suited for traditional or classic design approaches where restraint and subtlety are key.
結果元: Grok 2 · テスト済み Feb 15, 2026Photograph facing the window, not away from it. AI reads light direction from photos to suggest placement, colors, and which walls to paint as accent walls.
Name the things you love, not just what you want to change. If you don’t protect your favorites, AI redesigns everything — including the pieces you chose carefully.
Ask for “one thing to remove.” The best improvement is often subtraction. AI defaults to suggesting you buy more. Force it to identify what’s hurting the space.
