How to choose Design & Architecture tools
Floor Plan Maker is the only completely free tool here and needs no login. Arcadium, Floor Plan Creator, and Cedreo all have free plans but limit you to one project each. On the AI redesign side, Interior AI, RoomGPT, and Paintit.ai are paid only. RoomGPT starts at $9.99 a month, Paintit.ai at $24.99 a month, and Interior AI at $60 a month. HomeDesignsAI publishes no price at all and asks you to contact sales.

HomeDesignsAIPhoto redesign vs. drawing from scratch
AI redesign tools take one photo of your room and return a new look in under two minutes. Interior AI, RoomGPT, and Paintit.ai all work this way and cover furniture suggestions, room styling, and renovation previews. Arcadium takes a different approach: you draw the layout yourself and get a 3D walkthrough. Floor Plan Maker and Floor Plan Creator are also drawing tools, letting you build a 2D plan and flip it to 3D. If you have a room and want to see it differently fast, the photo tools get there first. If you are planning a new layout or a build, the drawing tools give you more control.
What you pay before seeing any result
Floor Plan Maker costs nothing and asks for no login. Arcadium, Floor Plan Creator, and Cedreo let you start on a free plan, though each caps you at one project. RoomGPT offers a free trial with limited use before billing $9.99 a month. Paintit.ai charges $24.99 a month with no free plan. Interior AI charges $60 a month or $390 a year, also with no free plan. HomeDesignsAI and Cedreo's paid tiers name no price on the site; both require a sales call before you know what you will pay.
How much of the work the tool covers
Some tools stop at the visual. RoomGPT and Interior AI show you a redesigned room but do not produce a floor plan or a furniture shopping list you can act on directly. Paintit.ai goes a step further by connecting furniture suggestions to a shopping step inside the same tool. Cedreo covers floor plans, 3D views, roof design, and site planning, which makes it the widest option here for anyone designing a whole house. HomeDesignsAI handles interiors, exteriors, gardens, and staging from one place, though none of its plan prices are public.

Frequently asked questions
Which Design & Architecture tools are completely free?
Floor Plan Maker is the only tool here that costs nothing and requires no login. Arcadium and Floor Plan Creator each cap the free plan at one project. Cedreo also has a free plan at $0 a month but restricts it to basic drawing features and one project. RoomGPT offers a free trial with limited use, then bills $9.99 a month. Every other tool on the AI redesign side requires a paid plan from the start.
Which tool works well for visualizing a room before renovating?
RoomGPT and Interior AI both take one photo and return a redesigned room quickly. RoomGPT starts at $9.99 a month and shows multiple style options. Interior AI starts at $60 a month and adds features like 3D walkthrough videos and outdoor design. Arcadium does this too on its free plan, though it is built around drawing a layout rather than uploading a photo.
Which tools help with furniture recommendations?
Interior AI, RoomGPT, and Paintit.ai all suggest furniture as part of their redesign output. Paintit.ai connects the suggestion directly to a shopping step inside the tool, at $24.99 a month. Interior AI and RoomGPT show furniture in the redesigned image but do not link to a shopping step in the same way. All three are paid only.
Which tool is good for drawing a 3D house plan?
Cedreo is the most complete option for a full house. It covers floor plans, 3D views, roof design, and site planning, though its paid tiers require a sales call for pricing. Floor Plan Maker is free and handles 2D and 3D layouts with no login needed. Arcadium's free plan covers one project and includes a 3D walkthrough, while Floor Plan Creator adds a symbol library and multi-floor support from $6.95 a month.
Are there Design & Architecture tools for UX or product design?
Zeplin, Proto.io, and Axure RP are listed here but are built for screen design and prototyping rather than rooms or buildings. Proto.io starts at $29 a month for creating interactive prototypes without coding. Axure RP also starts at $29 a month per user and adds diagrams and documentation. Neither is suited to interior or architectural work.

Axure RPWhich tools publish their prices and which do not?
RoomGPT, Paintit.ai, Interior AI, Arcadium, Floor Plan Creator, Proto.io, and Axure RP all show prices on their sites. HomeDesignsAI lists no prices for any plan and asks you to contact sales. Cedreo shows a free plan at $0 but lists no price for its Personal, Pro, or Enterprise tiers. Knowing this before you apply saves time.
