Best AI Interior Design Tools in 2026: Free Plans and Prices
Eight AI interior design tools compared on what each free plan keeps, its watermark and renewal rules, and the cheapest paid step.
Short answer: Homestyler is the best free plan for designing a room, with unlimited 1K renders and 100,000+ free 3D models at no cost. Planner 5D is the pick for a measured floor plan, because its free plan has no time limit. Prices here were verified on vendor pricing pages in October 2026.
Two of the eight tools have no ongoing free plan. Decor8 AI asks you to subscribe before you start, and Collov AI offers only a watermarked trial.

Homestyler
The strongest free plan for designing a room: unlimited 1K renders and a large free model library, with 4K output bought per use.
- Pricing
- Free Basic plan with unlimited 1K renders; Pro $4.90/mo as a first-month offer, Master $9.90/mo, in US dollars
Best for: Anyone designing a whole home in 3D who wants free renders before paying for 4K output
Pros
- Basic is free with unlimited 1K renders and 100,000+ free 3D models and materials
- The cloud-based 3D floor planner runs in the browser, with no download to start
- Pro adds 75 renders each at 2K and 4K per month, watermark removal and 100 AI credits
Cons
- Free renders work only on some render types, and a 4K render is bought each time
- Pro's $4.90 is a first-month offer, so confirm the renewal price at checkout before you subscribe
Planner 5D
The free plan has no expiry and includes half the furniture catalog, but AI Studio credits and photorealistic renders are paid upgrades.
- Pricing
- Free plan with no time limit; Premium $19.99/mo or $59.99/yr; Professional $49.99/mo or $399.99/yr
Best for: Homeowners who want to test room layouts, furniture placement and traffic flow before spending money
Pros
- Free users can create and share projects in 2D and 3D, and invite a partner or contractor to edit
- The free plan has no time limit, so a layout can stay open while you compare options
- Premium adds the full 10,000+ item catalog, floor plan recognition and 100 AI Studio credits a month
Cons
- AI Studio credits, AI floor plan recognition and photorealistic renders all sit behind a paid plan
- Premium's 100 monthly credits buy about 50 Nano Banana 2 images at 1K, by the page's own estimate
Maket
The free plan builds a single-floor plan and renders, but PDF, DXF and render downloads need a paid plan.
- Pricing
- Free: 30 one-time credits, no card; Homeowner $20/mo with 300 credits; Pro $100/mo with 3,000
Best for: Homeowners who start with a floor plan and want AI renders of each room
Pros
- Floor plan generation costs 20 credits per floor and each render costs 10, so the free 30 cover one floor and one render
- Homeowner's 300 credits refresh each month, and top-up packs never expire
- Multi-floor plan generation is on Homeowner, not the free plan
Cons
- Free projects can be shared by link, but downloadable exports are for paid plans only
- The 30 free credits are one-time, so the free plan does not renew for a second room
ReimagineHome
Five free designs with no card, then monthly credits: one credit per design, and two when a design also matches real products.
- Pricing
- 5 free designs, no card; Essential $14/mo (30 credits), Pro $29/mo (200), Advanced $49/mo (400), Agency $99/mo (900)
Best for: Real estate agents and interior designers who want a conversational flow and real products placed in the room
Pros
- New users get 5 designs with the same AI as the paid plans, and no card is needed to start
- Chatting and idea exploration cost no credits, so you can refine a brief before spending any
- Essential lists watermark-free, shareable images at $14 a month
Cons
- Essential has no conversational flow and no real shoppable products, which Pro adds
- Credits are per design, so a multi-room project can use the monthly allowance quickly
Remodel AI
Three free designs cover all 30+ styles at standard quality, and HD downloads with no watermark start at the Pro plan.
- Pricing
- Free: 3 designs; Pro $29/mo billed $349/yr; Premium $49/mo billed $599/yr; Ultra $99/mo billed $1,199/yr
Best for: Homeowners testing many interior styles who want one room restyled quickly from a photo
Pros
- The free plan includes every interior style, so you can judge the look before paying
- Pro adds virtual staging, floor and wall paint, object removal and exterior design, not only restyling
- Ultra adds a commercial license and API access for teams that bill client work
Cons
- Free designs are standard quality, and HD downloads plus no watermark start at Pro
- Pro is $29 a month or $349 billed yearly, so confirm the monthly price at checkout before you commit to a year
Spacely AI
The free plan is watermark-free with a commercial license, but the page lists 40 trial credits and does not say they renew.
- Pricing
- Free forever with 40 trial credits; top-ups $9 for 200 credits; paid plans priced on a render slider
Best for: Architects and interior designers rendering rooms from SketchUp, Revit, AutoCAD or Rhino models
Pros
- The free plan lists high-resolution downloads, private mode, a commercial license and watermark-free output
- Top-up credits never expire, so a project can pause without losing purchased credits
- Personal includes integrations with SketchUp, Revit, AutoCAD and Rhino
Cons
- Top-ups are available to subscribers only, so the $9 pack of 200 credits needs a paid plan first
- Paid plans are priced on a render-count slider, so the cheapest paid step depends on how many renders you need
Collov AI
Built for listing photos: Standard adds furniture, swaps styles and removes watermarks, with a commercial license from the first paid plan.
- Pricing
- No free plan, only a watermarked trial; Standard $19/mo billed $228/yr with 60 photo credits
Best for: Real estate agents who need quick staging and style swaps for listing photos, with commercial rights
Pros
- Standard's 60 photo credits include unlimited regeneration, no watermark and a commercial photo license
- Standard includes the furniture removal tool and a 10-second turnaround
- Billed yearly, Standard costs $228 a year, so the annual bill is the number to budget for
Cons
- The free offer is a trial with watermarked output, and the trial credits vary by feature
- Its tools center on listing photos rather than floor plans, so a whole-home plan is outside its range
Decor8 AI
A flat $14.99 a month covers unlimited room redesigns and 56+ styles, with a 7-day refund, but there is no free tier to test first.
- Pricing
- No free plan; Unlimited $14.99/mo billed monthly, with 20% off on annual billing
Best for: Homeowners and designers who want unlimited redesigns on one flat monthly fee, with no per-image charges
Pros
- The unlimited plan covers 56+ interior styles, virtual staging for empty rooms and paint or cabinet color visualization
- A full refund is available within the first 7 days if the plan is not right for you
- Cancel anytime with no cancellation fee, and access runs to the end of the billing period
Cons
- You subscribe before you can design anything, so there is no free trial of the app itself
- Unlimited means no per-image fees in the app, but developer API use is billed per image
What it is
An AI interior design tool turns a photo of a room, a floor plan or a text prompt into a styled version of that room, so you can test furniture, paint and layout before you buy.
General image tools such as Midjourney can draw a room but cannot plan one, so this list leaves them out (see our Midjourney review).
Free plans differ on four things: how many renders you get, whether the allowance renews, whether exports carry a watermark, and whether the result may be used commercially.
If you only need pictures rather than a room, our best AI image generators ranking covers general image models.
Why it matters
Renders cost credits, and a free plan that looks generous can run out after a single room. Remodel AI's three free designs cover one room in one style, while Homestyler's Basic plan allows unlimited 1K renders.
Pick by the allowance first, then compare the cheapest paid step, because the watermark or the download is usually where a free plan stops being useful.
Restyling a photo and building a floor plan are different jobs.
Free AI photo editors and free AI image upscalers do not plan a layout, and if you want to animate a finished room, see free AI image-to-video generators.
Key features to look for
Pricing
Every plan and price on this page was read on the vendor's own pricing page in October 2026, and all figures are in US dollars.
Sources: Planner 5D pricing, Homestyler pricing, Maket pricing, ReimagineHome pricing, Remodel AI pricing, Spacely AI pricing, Collov AI pricing and Decor8 AI pricing.
Some pages display euro prices to some visitors.
Planner 5D's own FAQ states its US dollar prices, which this page uses. Homestyler prices its Pro and Master plans per month in US dollars. The Pro figure is a first-month offer, so confirm the renewal price at checkout.
Methodology: we kept eight tools whose pricing pages state plan prices in US dollars.
We ranked them by the free allowance first and the cheapest paid step second, and checked each figure against the page it came from. Collov AI and Decor8 AI have no ongoing free plan, so they close the list. Spacely AI prices its paid plans on a render slider, so we quote its top-up pack as the fixed price.

The bottom line
Start with Homestyler if you want to design a room for nothing, since its free plan includes unlimited 1K renders. Choose Planner 5D when you need a measured floor plan and the free plan has to last.
Maket is the one to price if you want AI floor plans with renders, and ReimagineHome suits anyone who wants a conversational flow on a monthly plan.
Skip Decor8 AI for a free test, since it has no free plan, and treat Collov AI as a listing tool rather than a room planner (Toolradar profile).
