RoomGPT

What is RoomGPT?

RoomGPT is an AI interior design tool that restyles a photo of your room in a theme you choose, such as Modern or Scandinavian. Its homepage calls it a personal AI interior designer for picturing a room before you renovate.

The process is simple. You upload a photo, pick a style, and an image model trained to follow the structure of the original picture paints a new version of the same space. The open-source first version uses ControlNet hosted on Replicate, while the commercial site adds accounts, payments and extra features.

RoomGPT was built by developer Hassan El Mghari, known online as Nutlope, who is listed as the contact on the site. The homepage says more than 4 million people have used it and that it has appeared in Business Insider, NBC and Yahoo News. The service remains active and was running a discount promotion on its homepage in October 2026.

Key Features

Speed and simplicity define RoomGPT: one uploaded photo and one theme choice produce a full room redesign in well under a minute.

• Photo-based redesign: You upload a photo of an existing room and receive a restyled version of the same space. The model keeps the rough layout of walls and windows, so you see a new look in your own room rather than a stock image.
• Preset design themes: A theme menu sets the style of each render, and reviews list options such as Modern, Scandinavian, Industrial, Bohemian and Tropical. Reviewers count somewhere between 10 and 20 presets, which covers most mainstream looks.
• Fast generation: Each design takes roughly 15 to 30 seconds, according to a September 2026 review. That speed makes it practical to try several themes on one photo while you browse ideas on a sofa.
• Credit packs instead of subscriptions: Generations are paid for with one-off credit packs, and one credit buys one design. No monthly plan is required, which suits a homeowner planning a single room project.
• Free trial generations: New accounts reportedly receive between one and three free designs after signing in with Google. That is enough to judge whether the output quality fits your room before you pay anything.
• Open-source origins: The first version of RoomGPT is published on GitHub under an MIT licence, built on ControlNet, Replicate and Bytescale. The README says the hosted site adds sign-in, payments and extra features beyond that code.

Pros

Homeowners pick RoomGPT for cheap, quick inspiration, since credit packs reportedly cost from about 15 cents a design with no subscription.

• Very simple workflow: The whole process is one photo, one theme and one click. Homeowners with no design software experience can produce a first concept within a minute of signing in.
• Low cost per design: Reported packs work out at about $0.15 to $0.30 per design. Trying ten looks for a living room therefore costs a few dollars rather than a consultation fee.
• No recurring bill: Credits are bought once, so there is no subscription to remember to cancel. This suits occasional users who redecorate one room every year or two.
• Wide adoption: The official homepage says more than 4 million people have used the service, and it lists coverage by Business Insider, NBC and Yahoo News. That track record suggests a stable, well-tested product.
• Transparent technology: Because the original code is public, developers can study how the image pipeline works. Hobbyists can even deploy their own copy of the early version on Vercel.

Cons

Whole-room rerolls are RoomGPT’s main weakness, because you cannot edit one object, and walls or windows sometimes shift between renders.

• No targeted editing: Every generation redraws the whole room, so you cannot keep one sofa while changing the curtains. Reviewers recommend tools with instruction-based editing if you need step-by-step refinement.
• Structural drift: Reviews note windows moving and built-in units warping in some renders. Treat each image as mood inspiration, not as a plan your builder or joiner can follow.
• Prices hidden until login: The official site shows plans only after you sign in, and its homepage advertised a 60 per cent discount code. Check the final price in your account before buying credits.
• No measurements or shopping: RoomGPT does not produce floor plans, dimensions or links to real products. You will need a planner such as Planner 5D or a shoppable design tool to turn ideas into purchases.
• Inconsistent across rooms: A real estate comparison found results vary from image to image across a set. Agents staging a whole listing may struggle to keep a consistent style between rooms.

Who is Using RoomGPT?

Homeowners planning a makeover form the core audience, with the official site claiming more than 4 million users worldwide.

• Homeowners: They try new styles on a room before buying paint or furniture. Comparing several themes helps settle decisions about colour and mood.
• Renters: They explore cosmetic changes that need no building work. Images guide choices on rugs, lighting and soft furnishings.
• Interior designers: They generate quick mood images to start a client conversation. The renders open discussion rather than replace detailed design drawings.
• Estate agents: Some use it for quick inspiration on empty or dated rooms. Listing use needs care, because virtual changes should be clearly disclosed to buyers.

Pricing

RoomGPT sells one-off credit packs from a reported $9 for 30 credits, after a small free trial (review figures, October 2026).

The official site shows prices only after login, so these figures come from two 2026 reviews that agree with each other; they differ only on the free allowance, which one puts at a single design. The homepage also advertised a 60 per cent discount code at the time of writing.

Disclaimer: promotions on this site change without notice, so sign in and read the live credit prices in your account first.

What Makes RoomGPT Unique?

Open-source roots give RoomGPT an unusual profile: its first version is public on GitHub under an MIT licence, with more than 10,000 stars. Most rival room designers are closed products, so developers rarely see how the image pipeline is assembled.

Its pricing model is the other difference. Many competitors push monthly subscriptions with staging, shopping or floor-plan features, while RoomGPT keeps to one job and charges per pack of credits. That makes it a low-commitment way to test ideas for a single room.

Compatibilities and Integrations

Any modern browser is all RoomGPT needs, as the hosted product offers no apps, plugins or public API.

• Platform: RoomGPT is a website that works in desktop and mobile browsers. No official mobile app was found on the homepage.
• Sign-in: Accounts use Google login, according to 2026 reviews. The design page itself is behind a login link.
• Input and output: You upload a standard room photo and download the generated image. Reviews report a maximum of about 2,048 pixels on the long edge.
• Developer options: There is no public API for the hosted service. The MIT-licensed GitHub code lets developers build their own version using Replicate.

RoomGPT Tutorials

Getting a first redesign takes six short steps, and good lighting in your photo matters more than any setting.

1. Go to roomgpt.io and sign in with your Google account.
2. Take a well-lit, straight-on photo of the room with clutter removed.
3. Upload the photo and choose the room type and a design theme.
4. Generate the design and wait about half a minute for the render.
5. Try two or three more themes on the same photo to compare looks.
6. Download the images you like and share them with your designer or household.

How We Rated It

RoomGPT scores 3.3 out of 5 because it is fast, cheap and easy, but it offers little control and no editing.

Summary

RoomGPT suits homeowners and renters who want quick, inexpensive ideas for restyling a single room from a photo. It is very easy to use, and credit packs avoid a monthly bill. The main limitation is control, since every render redraws the whole room and structural details can drift. Professionals who need consistent sets, measurements or shoppable products should look at more specialised tools. For the best results, shoot the room in daylight from a corner and test two or three themes before buying a larger pack.
