Whether you're a seasoned interior designer or a DIY home decorator, there's one tool you shouldn't overlook in 2025: GPT-4o. With just one sentence, you can change your curtains—or even generate a complete, photorealistic living room design. It’s an incredibly powerful assistant for anyone looking to visualize home transformations before making real changes.
In this blog, we’ll walk you through 4 game-changing ways to use GPT-4o for interior design, complete with prompt templates to get you started. The third feature is especially jaw-dropping—you won’t want to miss it.
Let’s dive in.
1. Swap Individual Decor Elements (like Curtains or Sofas)
Use Case
Want to see how new curtains would look in your living room before buying them? Or maybe you'd like to preview a leather sofa in place of your current fabric one? GPT-4o can help you swap specific furnishings into your own space, giving you an accurate visual mock-up.
Prompt Example
Replace the curtains in Image 1 with the curtains from Image 2. Keep all other elements the same. Set image ratio to 4:3.
Tips
- Take a well-lit, wide-angle photo of your room
- Upload clear images of the decor items you want to test
- Wait a couple of minutes while GPT-4o generates the output
This also works for rugs, tables, lamps, and more. While minor details may differ, the overall visual result is remarkably reliable for reference.
2. Adjusting Soft Furnishing Compatibility
Use Case
You've already picked out your favorite curtains — now comes the tricky part: what kind of flooring, sofa, or wall color will match best? If you're unsure, let GPT-4o help! Try swapping out different background styles and color schemes to see which combination brings out the best in your space. You might be surprised which one becomes your new favorite.
Prompt Example
“Can you show me what this linen curtain would look like in a room with light oak flooring and a cream-colored sofa?”
“Help me visualize this curtain in different settings — one with a dark wood floor and navy couch, and one with white tiles and a grey sofa.”
Tips
- Be Specific: Mention the curtain color/material and what elements you want to test, like flooring, sofa, or wall paint.
- Try Different Styles: Ask for visualizations in multiple interior styles — like minimalist, boho, Japandi, or mid-century modern.
- Think About Lighting: Natural light, warm-toned lamps, or even cool LED light can affect how your curtain looks in real life.
- Save Your Favorites: Keep screenshots of your favorite combinations so you can compare them later when decorating.
3. Mix & Match to Create Your Own Style
Use Case
Already picked out several pieces of furniture, but not sure how they’ll look together in one room? GPT-4o can combine multiple furniture photos into a single cohesive scene, styled exactly the way you want.
Prompt Example
Combine the furniture from Images 2 into the space shown in Image 1. Style the room as a cozy modern Scandinavian living room.
Tips
- Upload your room photo plus all the furniture images you want to use
- You can upload images with or without background (cutouts are fine too)
- Mention the design style (e.g., Japandi, Mid-Century, Boho)
The result? A realistic, AI-powered mood board that helps you visualize your dream setup instantly.
4. Style Replication: Recreate the Look You Love
Use Case
Fell in love with a design you saw on Pinterest or Instagram? Want to recreate that exact style in your own home? GPT-4o can analyze your reference images and generate a near-identical look tailored to your space.
Prompt Example
Based on the design and furniture in Image 2, create a similar living room setup in the space shown in Image 1. Keep room structure and lighting consistent.
Tips
- Upload a photo of your space plus as many reference images as you like (up to 10)
- Use clear, well-lit photos for best results
-
The more visual references you provide, the closer the match
This is ideal for anyone who wants to “copy the homework” of a dream space and adapt it to their own home environment.

Pro Tips for Best Results
- Use high-resolution, full-view photos of your room
- Reference images should be clear, with minimal clutter
- Be patient—AI generation may take 1–3 minutes
- If the first output isn’t perfect, tweak your prompt and try again
- Make sure lighting angles and image ratios are consistent across uploads
