Short answer: AI Smart Decor is the best paid AI interior design app for most homeowners. Plans start at $9/month on the web for 200 images, and a new account gets 3 free images to try it first. You upload a photo of your own room, describe the change, and keep refining the same room step by step, with up to 6 of its 50 styles side by side. Remodel AI suits people who want one-click tools, Interior AI suits very high volume, REimagineHome suits designs with real products, and Planner 5D or Homestyler suit measured 3D floor plans.

Vendors change prices often, so confirm on their site before you buy.
The split that matters most is the "Type" column. Photo redesign apps change a photo of the room you already have. Planners build a measured model of the room from scratch. Many people end up paying for one of each, but if you only pay for one, pick the type that matches your question: "how will it look?" or "will it fit?"
What do you actually get when you pay?
A paid plan buys you five things. Check each one against the room you are working on.
- Room to iterate. Good results rarely come on the first try. You nudge the prompt, change the rug, try a warmer floor. A real monthly allowance lets you treat each image as cheap.
- Editing, not just restyling. The best paid apps let you change one thing on the last result instead of rolling a whole new room. Some apps keep editing for their higher tiers.
- Clean downloads. Paid output is usually watermark-free and full resolution, so you can share it with a partner, a contractor or a seller.
- The full style library. Modern farmhouse, mid-century modern, craftsman, Japandi and coastal are the styles US homeowners ask for most. Check that the ones you want are on the plan you pick.
- Commercial use. Agents, landlords and contractors need the right to use images for work. Read the plan terms before you put an image in a listing or a client deck.
Why is AI Smart Decor the best paid pick for most homeowners?
AI Smart Decor puts every feature on every plan. The $9 Basic plan uses the same editor and image model as the $99 Ultra plan. You pay for volume, not for unlocked tools.
- Describe the change, keep your room. Type "paint the walls sage green and add a jute rug" and the next edit builds on the last one. Every step is saved, and you can branch from an earlier step if a later one goes wrong.
- Compare up to 6 styles at once. Explore turns one photo into up to 6 different styles in a single run, picked from 50 interior styles across 10 room types.
- Show it what you mean. Add a photo of a sofa or a light fixture as a reference, or brush over the part of the room you want changed.
- Use the result. Paid downloads are watermark-free PNGs that keep your photo's shape, up to 3,840 px on the long side. A 2x upscale uses no credits, and an optional 4K upscale costs 3 image credits.
- Shop the look. "Find furniture to buy" opens Google Lens on any result.
- Pick it up anywhere. Your rooms and steps show on the web and in the iPhone app when you sign in with the same account.
Pricing: Basic $9/month (200 images), Lite $29/month (800), Plus $49/month (2,000), Ultra $99/month (5,000). Annual plans are $108, $249, $449 and $899, so Lite, Plus and Ultra save money on a yearly bill while Basic costs the same either way. The allowance runs on a rolling 30 days from your first generation. Every plan lists a commercial license. Cancel anytime, effective at the end of the billing period. There are no refunds, which is one more reason to use the 3 free images first.
The iPhone app is sold separately in the App Store and focuses on prompt edits. Explore and upscaling are on the web.
Pick it if you are redesigning one room or a whole house from photos and want to keep improving the same image rather than starting over each time.
See your own room redesigned before you buy a thing. Upload a photo, describe the change, and compare 50 styles on the space you live in. Plans start at $9/month for 200 images, and a new account gets 3 free images. Try AI Smart Decor with 3 free images
How do the other paid apps compare?
Remodel AI: best for one-click tools
Remodel AI gives you 8 separate tools, such as paint or flooring changes, and more than 30 interior styles. Pro is $29/month or $349/year for 1,000 designs, Premium is $49/month for 5,000 and Ultra is $99/month for 25,000. That makes it the lowest cost per image here once you use the volume. It runs on iPhone and Android, and the free plan gives 3 designs. Pick it if you prefer pressing a "change floor" button to writing a sentence.
Interior AI: best for very high volume
Interior AI is built for changing a room's style while keeping its layout. Pro is $49/month for 1,000 designs, or $349 billed yearly, but its pricing page labels Pro renders "low quality" and leaves out editing, staging and upscaling. Premium at $99/month adds those tools with "medium quality" renders and 5,000 designs. Ultra at $199/month is its photorealistic tier with 25,000 designs. There is no free plan. It suits design studios and power users who know they will make thousands of images. For a closer look, see AI Smart Decor vs Interior AI.
REimagineHome: best for real products
REimagineHome mixes redesign and staging with furniture you can actually order. Essential is $14/month for 30 credits, Pro is $49 for 200, Advanced is $79 for 400 and Agency is $99 for 900. New users get 5 free designs. The entry plan is cheap per month but expensive per image, so it suits people who make a few careful designs rather than many quick ones.
Planner 5D: best for measured floor plans
Planner 5D is a planner, not a photo editor. You draw the room, place furniture to scale and view it in 3D. There is a free plan, Premium is $19.99/month or $59.99/year, and Professional is $49.99/month or $399.99/year. It runs on the web, iPhone, Android, Mac and Windows. Pick it when the question is "will an 84-inch sectional fit?" rather than "will sage green look good?"
Homestyler: best low-cost 3D planner
Homestyler's free Basic plan includes 1K renders, and Pro starts at $4.9/month, with Master from $9.9/month. Like Planner 5D, it builds a model of the room rather than editing your photo. It is a good, low-cost way to test a layout.
RoomGPT: best for no subscription
RoomGPT sells one-time credit packs, starting at $9 for 30 credits. It regenerates the whole room each time, which is fine for a quick "would this style work?" check but slower when you want to fix one detail.
How much do you really pay per image?
The price on the plan card hides the number that matters: what each usable image costs. Here is the math at each app's entry and top tiers.
| Plan | Monthly price | Images | About per image |
|---|---|---|---|
| AI Smart Decor Basic | $9 | 200 | 4.5 cents |
| AI Smart Decor Lite | $29 | 800 | 3.6 cents |
| AI Smart Decor Ultra | $99 | 5,000 | 2 cents |
| Remodel AI Pro | $29 | 1,000 | 2.9 cents |
| Interior AI Pro ("low quality") | $49 | 1,000 | 4.9 cents |
| Interior AI Premium | $99 | 5,000 | 2 cents |
| REimagineHome Essential | $14 | 30 credits | 47 cents |
| Collov AI Standard | $19 | 60 photo credits | 32 cents |
Two lessons come out of that table. First, the lowest monthly bill is AI Smart Decor at $9, and for one or two rooms, 200 images is more than most people use. Second, per-image cost only matters if you use the allowance. A 1,000-design plan you use 80 times costs more per image than a 200-image plan you use 80 times.
Is a paid AI app cheaper than hiring a designer?
Much cheaper, and it does a different job. Havenly's Online Full package lists at $199 (on sale for $99), and Decorilla's packages start at $599 for Bronze. Those prices buy a person's taste, a shopping list and revisions. A $9 AI plan buys you hundreds of fast looks at your own room.
A sensible order for many homeowners: use an AI app to narrow down the style you like, then hire a designer only if you need help with sourcing or a complicated layout. Our guide on how much AI interior design costs walks through full-project budgets.
When is a free tool enough?
A free allowance is enough when every one of these is true:
- You are styling one room for your own eyes.
- You only want a rough sense of a style, not a refined result.
- You do not need to share the image with anyone.
The moment you start refining ("same room, but warmer floors and a smaller sofa"), free allowances run out. That is normal. Most rooms take five to ten edits before they look right.
How do you pick the right paid plan?
Match the plan to the job, not the feature list.
- One room, such as a living room refresh: AI Smart Decor Basic at $9/month. 200 images covers a room with plenty of retries.
- A whole house before move-in or a remodel: AI Smart Decor Lite at $29/month for 800 images, or Remodel AI Pro if you prefer one-click tools.
- Several listings or client projects a month: AI Smart Decor Plus ($49, 2,000 images) or Ultra ($99, 5,000 images). Interior AI Premium ($99) is the other strong option at that level.
- A new layout or moving walls: add Planner 5D or Homestyler for measured plans, then use a photo app for finishes.
What should you test in the first 3 free images?
Use your trial on your hardest room, not your easiest. Here is a simple test plan:
- Image 1: a full restyle. Upload a corner photo of your living room and ask for modern farmhouse or mid-century modern.
- Image 2: one change on that result. "Replace the carpet with light oak flooring, keep everything else."
- Image 3: a detail fix. Brush over the coffee table and ask for a round wood table instead.
If the third image still looks like your room, and you would show it to someone, the paid plan is worth it. Our guide on whether AI interior design is worth it covers more ways to judge.
