# Interior AI vs RoomGPT: Home Design Tools Compared
Want to redesign your home or office but don't have the budget for an interior designer? AI-based interior design tools have reached an incredible point in 2026. You take a photo of your room, upload it, and within seconds see it redesigned in different styles. The two most popular tools in this space are Interior AI and RoomGPT. We tested both in our own homes and are sharing the results.
Interior AI: Professional-Quality Interior Transformation
Interior AI is one of the best-known tools for generating interior designs from a photograph. You upload a photo of your room, select a style (modern, minimalist, Japanese, industrial, etc.), and within seconds your room gets a completely new look.
We tested Interior AI with a photo of our living room and the results truly surprised us. The image generated in the "modern minimalist" style particularly preserved the existing room structure (windows, doors, dimensions) while changing only the furniture and decoration. The color tones on the walls, light reflections, and shadows looked extremely realistic.
Another strong point of Interior AI is the declutter feature. When you provide a photo of a messy room, it first empties the room and shows the clean version, then applies the new design. This feature is golden for real estate professionals — you can instantly improve photos of a house for sale.
However, Interior AI's pricing can be somewhat steep. The free plan is very limited, and you need the pro plan for professional use. Also, it can sometimes produce inconsistent results in architecturally complex rooms (angled corners, multiple sections).
RoomGPT: Accessible and Fast Room Design
RoomGPT is an interior AI tool offering more accessible pricing and a simple user experience. The open-source-based platform has a rapidly growing user base. The basic concept is the same: upload a room photo, select a style, get the new design.
When we tested RoomGPT in our bedroom, we noticed how quickly results came. While Interior AI made us wait 10-15 seconds, RoomGPT produced results in 5-8 seconds. Speed is an important factor, especially when you want to try multiple styles.
One of RoomGPT's most fun features is the variety of theme options. Beyond standard modern, minimalist, and Scandinavian choices, it offers more creative themes like "tropical," "palace," and "gaming room." This feature is great especially for those looking for inspiration.
However, RoomGPT's visual quality falls a step behind compared to Interior AI. Particularly in light and shadow consistency, you can sometimes get artificial-looking results. Furniture details can sometimes be blurry.
Feature-by-Feature Comparison
| Feature | Interior AI | RoomGPT | |---------|-------------|----------| | Visual Quality | 9/10 - Professional level | 7.5/10 - Good but noticeable gap | | Realism | 9/10 - Superior light/shadow | 7/10 - Sometimes artificial | | Speed | 7/10 - 10-15 seconds | 9/10 - 5-8 seconds | | Style Variety | 8/10 - 15+ styles | 8.5/10 - 20+ styles | | Declutter | 9/10 - Available and successful | 5/10 - Limited | | Ease of Use | 8/10 - Intuitive | 9/10 - Very simple | | Space Preservation | 9/10 - Preserves structure well | 7.5/10 - Sometimes alters | | Furniture Detail | 8.5/10 - Detailed | 7/10 - Sometimes blurry | | Exterior Support | 8/10 - Garden and terrace | 6/10 - Limited | | Multiple Outputs | 8/10 - Multiple results | 7/10 - Single result |
Pricing Comparison
Interior AI's pricing works per render. The free plan offers 1-3 renders (for trial purposes). The Pro plan is $39/month with 100 renders. Business plan is $99 with 500 renders. An Enterprise plan is also available. Cost per render on the Pro plan is approximately $0.39.
RoomGPT is more affordable. The free plan offers a few renders. The Pro plan starts at $9/month with 100 renders. Premium plan is $29 with 500 renders. RoomGPT's cost per render on the Pro plan is approximately $0.09 — 4 times cheaper than Interior AI.
In our assessment, RoomGPT wins by a clear margin in cost-performance. However, the quality difference cannot be ignored. If you're producing professional renders for client presentations, Interior AI's price delivers the value it deserves.
