Best Free AI Interior Design Apps in 2025

The best free AI interior design app in 2026 is RoomGPT, which allows you to upload a photo of your space and see it reimagined in styles like “Modern,” “Industrial,” or “Scandinavian” in seconds. If you need more granular control over furniture placement, REimagineHome and Decoratly are excellent alternatives. These tools are perfect for visualizing a room makeover before you spend a single dollar on paint or furniture.

All three have free tiers. Here’s an honest breakdown of what each app can and can’t do, so you choose the right one for what you actually need.

Top 5 Free AI Interior Design Apps Compared

App-by-App Mini Reviews

RoomGPT

RoomGPT is the easiest starting point. Upload a photo, pick a design style (modern, Scandinavian, maximalist, etc.), and it generates 3-4 redesigned versions of your room. The AI sometimes misreads proportions or produces slightly surreal results, but the good outputs are genuinely useful for visualising a direction before committing to it. Free users get about 5 renders per day.

Decoratly

Decoratly is more style-focused than RoomGPT. It has one of the broadest style libraries of any free app – from Japandi to Art Deco to Coastal – and applies them with reasonable accuracy. The free tier is slightly more limited (3 renders daily), but the quality per render is slightly higher.

REimagineHome

REimagineHome’s strongest feature is furniture placement – it’s better at putting virtual furniture into your actual space than any other free tool. Useful when you’re deciding between furniture pieces and want to see them in context before buying.

Planner 5D

The only app here that lets you design a room from scratch using a floor plan. You draw your room, place walls and windows, then drag and drop furniture. The 3D walk-through mode is genuinely impressive. The free tier limits which furniture items you can access, but there’s still a solid selection for planning purposes.

IKEA Kreativ

IKEA Kreativ is unique because it uses your real room (via phone scan or photo upload) and places actual, purchasable IKEA products into it. It’s more of a shopping tool than a design tool, but if you’re furnishing a space with IKEA products, it’s invaluable – and completely free.

What to Look for in an AI Design App

• Photo upload quality – the app is only as good as the image it’s working with; good natural lighting makes a big difference
• Style library – a wider range means more useful comparisons
• Editing control – can you move furniture, change colours, or are you locked into the AI’s output?
• Export/share options – some free tiers watermark images or restrict downloads
• Realistic rendering vs. conceptual – some apps show inspiration images; others actually edit your room photo

Honest Limitations of Free Tiers

Free AI design tools are genuinely useful for inspiration and direction. They are not reliable for precise planning. Proportions are often off, furniture sizes are approximate, and lighting in renders rarely matches real-world conditions. Use them to explore aesthetics and get a feel for a direction – then verify any specific furniture choices in reality before buying.

Most free tiers also limit renders per day. If you need to do a lot of experimenting, work in sessions across multiple days rather than hitting the limit quickly.
