The best AI app for interior design in 2025 is Roomgpt for instant room visualization and Houzz for comprehensive design planning – though the right choice depends on whether you want quick AI-generated room concepts or a full design tool with shopping integration.
AI has genuinely transformed how people plan spaces: you can upload a photo of your room and see it redesigned in multiple styles within seconds, without hiring a designer or buying a single piece of furniture.

Roomgpt: The Best for Quick Visual Concepts
Roomgpt is the most viral of the AI interior design tools – upload a photo of your room, select a design style (Scandinavian, mid-century modern, farmhouse, etc.), and receive a photorealistic redesign in under 30 seconds.
What it does well:
- Instant, visually impressive results
- Wide range of style options
- Easy enough for complete beginners
Limitations:
- Generated images are inspiration, not implementation plans
- Furniture shown is AI-generated, not purchasable items
- Results vary in realism depending on room photo quality
Best use case: Figuring out which design style you actually want before spending any money.
Houzz: The Most Complete Design Platform
Houzz is the most fully-featured design platform, combining AI-powered style discovery with a massive product catalog, contractor directory, and project management tools.
AI features include:
- Style quiz that narrows your aesthetic preferences
- “View in My Room” AR for specific purchasable products
- AI-powered product recommendations based on your saved photos
- Visual search (upload a photo, find similar products)
Best use case: Anyone seriously planning a renovation or redesign who wants to go from inspiration to purchase in one platform.
IKEA Kreativ: Best for IKEA Shoppers
IKEA Kreativ uses your phone’s camera to create a 3D scan of your room, then lets you virtually place IKEA furniture at accurate scale before buying anything. It’s free, accurate, and eliminates the “will this actually fit?” problem.
Best for: Anyone who shops primarily at IKEA and wants to visualize pieces before purchasing.
How to Get the Best Results From AI Design Apps
| Tip | Why It Matters |
|---|---|
| Use well-lit, clear room photos | Dark or cluttered photos produce worse AI outputs |
| Declutter before taking the photo | AI works better with cleaner starting images |
| Try multiple styles | The first result isn’t always the best – explore 5-6 variations |
| Use AI for inspiration, then verify | AI-generated rooms may not match real furniture dimensions |
| Combine tools | Use Roomgpt for style exploration + Houzz for actual shopping |
AI Design Apps vs Hiring a Human Designer
| Factor | AI App | Human Designer |
|---|---|---|
| Cost | Free-$150 | $1,500-$10,000+ |
| Speed | Minutes | Weeks to months |
| Personalization | Style-based | Deep personal knowledge |
| Implementation support | None | Full guidance |

The Bottom Line
The best AI app for interior design is Roomgpt if you want instant inspiration and visual concepts – and Houzz if you’re planning an actual project with real furniture purchases. Use AI tools to explore styles, validate your aesthetic preferences, and visualize spaces before spending any money. They won’t replace a skilled designer for complex projects, but for most home updates, they remove the guesswork completely.
