AI room redesign is not short on options. RoomGPT, Interior AI, Collov, Spacely, REimagine Home, and a growing list of newer entrants all do some version of "upload a photo, get a styled room back." If you're deciding between them, the honest differences are narrower than the marketing on any one of these pages, including this one, will tell you.
Price, without the credit-pack maths
RoomGPT sells credits: $9 for 30, scaling up from there. (Competitor prices were checked in September 2026 and change often, so confirm on their own pricing pages.) Collov's entry plan is listed at $19/month for 60 photo credits. Spacely's paid plans start at roughly $15/month, aimed at working designers who need masking and material-override controls most homeowners will never touch.
ThinkDecor's first month is 69p, then £4.99/month for 20 designs. That's not a promotional gimmick to get you in the door and then charge RoomGPT-level prices later, £4.99 is the actual ongoing price. If you just want to try one redesign before deciding anything, the barrier to entry is a fraction of what a credit pack costs.
Whether your actual furniture survives
This is the real technical difference, and it's worth being specific about it rather than just claiming it. RoomGPT and Interior AI are known for generating furniture that doesn't exist in your room, a new sofa, a new coffee table, sometimes a new floor plan's worth of stuff you never asked for. That's fine if you want inspiration. It's not useful if you're trying to answer "would this actual sofa look right in this actual room."
ThinkDecor's redesigns work from your photo's real geometry, the walls, windows and layout stay put, and what changes is what you tell it to change. If you only paint over one thing (see [Cleanup](/app/cleanup) and [Replace](/app/replace)), everything else in the photo is untouched pixel-for-pixel outside that area.
What ThinkDecor doesn't do that others do
No point pretending otherwise: Collov's product-matching (finding the actual real-world item closest to what's in the render) is more built-out than anything ThinkDecor offers today. Spacely's designer-grade masking tools go deeper than our Cleanup/Replace pair. REimagine Home is purpose-built for real estate staging at volume, batch-processing dozens of listing photos, which isn't what ThinkDecor is for.
Where to actually start
If you want the cheapest possible way to see whether AI redesign is useful to you at all, ThinkDecor's 69p first month is the lowest-commitment entry point in this comparison. If you're a working designer who needs precise material overrides across dozens of client rooms, Spacely is built for that job specifically and ThinkDecor isn't trying to be. If you're staging real estate listings at scale, REimagine Home is the right tool.
