In this guide, we compare five tools architects actually use in 2026: Vizcom, Maket.ai, SketchUp, Planner 5D, and ChatGPT. Four have genuine free plans; SketchUp does not, and we say so plainly. Every free-plan limit below was checked on the tool's official pricing page on October 21, 2026.

Quick Verdict
For architects, interior designers, and architecture students who want free AI help with concepts, floor plans, 3D models, and client-ready visuals. Our top pick is Vizcom for turning rough sketches into polished renders in minutes, with Planner 5D as the best free option for quick 2D and 3D space planning. One honest caveat: free tiers have real limits, such as monthly credits and no downloadable exports on Maket's free plan, and SketchUp has no free plan for individual architects at all.
Free AI Tools for Architects Compared

Vizcom
Vizcom is an AI rendering tool built for designers. Upload a rough sketch, type a short prompt describing materials and mood, and it generates a polished render in seconds. For architects, it shines at the concept stage, when you need to show a client what a facade or interior could look like before committing to a full 3D model.
The free Starter plan costs $0 per user per month with no credit card required, and includes 800 credits per month, basic AI creation tools, standard render speeds, 10 files, and 25 storage. 4K exports and Live Render are excluded. The lowest paid tier is Professional at $49 per user per month. Details: official Vizcom pricing page.
Maket.ai
Maket.ai generates residential floor plans from a text description. Describe the home you want, such as the number of bedrooms, style, and approximate size, and Maket produces a floor plan you can edit in its built-in editor and generate renders from. It is one of the few AI tools aimed directly at early-stage architectural planning rather than just images.
The free plan gives you 30 one-time credits with no credit card required. Floor plan generation costs 20 credits and a render costs 10, so the free plan covers roughly one plan plus one render: a good way to test whether the tool fits your workflow. Note the honest limitation: free projects can be shared with a link, but downloadable exports such as PDF and DXF are only on paid plans. The lowest paid plan is Homeowner at $20 per month with 300 AI credits per month. Details are on the official Maket pricing page.
SketchUp
As of October 21, 2026, SketchUp has no general free plan for individual architects. The official plans and pricing page lists paid subscriptions only, starting with Go Annual at $10.75 per user per month. The only free offering is SketchUp for Schools, which requires a Google Workspace for Education or Microsoft Education account and targets K-12 classrooms.
We include SketchUp because it remains the industry standard for 3D modeling in architecture, and it is worth knowing where it stands. Students and educators with a school account get the Schools version free; everyone else should budget for at least the Go plan. Compare the paid tiers on the official SketchUp plans and pricing page.
Planner 5D
Planner 5D is a 2D and 3D room planner on web and mobile. Draw floor plans, furnish rooms from a large catalog, and switch to 3D to walk clients through the space. For architects, it is ideal for fast interior layouts and showing non-technical clients what a room will feel like.
The free plan costs $0 with unlimited projects on web and mobile, and access to 50% of the furniture catalog while 10,000+ premium items stay locked. Professional features such as 4K renders, 360 walkthroughs, and CAD export are excluded. The lowest paid tier is Premium at $4.99 per month. It is also handy if you design restaurant interiors; for the client side, see our guide to the best free AI tools for restaurant owners in 2026. Details: official Planner 5D pricing page.
ChatGPT
ChatGPT is not a drawing tool, but architects use it daily as a thinking and writing assistant. It can draft design concept narratives, client emails, and project proposals, summarize building codes and zoning documents you paste in, brainstorm material palettes, and explain construction terms in plain language. Freelance architects and new studios also use it for fee proposals; for more studio-side tools, see the best free AI tools for startups in 2026.
The free plan costs $0 per month: unlimited text chats with GPT-6 (subject to abuse guardrails), plus limited uploads, image creation, voice chats, deep research, memory and context, and Codex access. Paid plans raise those limits. Verified on the official ChatGPT pricing page on October 21, 2026.
To test it honestly, we ran ChatGPT in free guest mode (no sign-in) on October 21, 2026, with the exact prompt and unedited response shown below.
🧪 We tested it ourselves
Prompt:
Describe a warm minimalist living room design concept in 3 bullet points.
What ChatGPT returned:
- Warm, Neutral Palette: Use creamy whites, warm beige, soft taupe, and earthy tones to create a calming atmosphere. Add subtle contrast with natural wood accents and touches of muted terracotta. - Simple, Cozy Furniture: Choose a streamlined sofa in linen or bouclé, a sculptural wooden coffee table, and a few thoughtfully placed cushions. Keep furniture low-profile and uncluttered to maintain an airy, minimalist feel. - Natural Textures & Soft Lighting: Layer a wool rug, linen curtains, woven baskets, and organic ceramic decor for warmth and depth. Incorporate warm ambient lighting, a statement floor lamp, and a few green plants to make the space feel inviting and lived-in.

Frequently Asked Questions
Are these AI tools really free for architects?
Four of the five tools above have genuine free plans, verified on their official pricing pages on October 21, 2026. SketchUp does not. Free tiers come with limits, such as monthly credits or restricted exports, so read each pricing page before planning a project around one.
Can AI tools replace an architect?
No. They speed up early design, visualization, and documentation, but they do not handle structural engineering, building codes, permits, or professional liability. They are fast assistants for the concept stage, not replacements for licensed professionals.
Which free AI tool is best for generating floor plans?
Maket.ai is the best fit if you want AI to generate a floor plan from text, though its free plan covers about one plan and one render. If you prefer to draw the plan yourself and visualize it in 3D, Planner 5D's free plan with unlimited projects is the better pick.
Does SketchUp have a free plan in 2026?
No, not for individual architects. SketchUp's only free offering is SketchUp for Schools, which requires a Google Workspace for Education or Microsoft Education account and is aimed at K-12 classrooms. The cheapest paid option is Go Annual at $10.75 per user per month.
Can I use AI-generated renders in client presentations?
Generally yes, but check each tool's terms. Vizcom says you keep full rights to your designs on all plans, though free-plan images may be used to improve its services. Maket's free plan has no downloadable exports, so you would present via a shared link instead.
Which free AI tool should I try first for a dental clinic design?
Planner 5D is a practical starting point for laying out treatment rooms and waiting areas in 2D and 3D on the free plan. If you take on healthcare projects, our guide to the best free AI tools for dentists in 2026 shows what your clients use on their side.
