The floor plan app that draws in 2D and builds in 3D
Draw a floor plan by clicking a few points, then watch it become an interactive 3D model you can walk through in first person. Measurements, square footage, and Gross Living Area calculate themselves. Export a pixel-perfect image or share a hosted 3D link on any device, straight from your browser.
No subscription required for 2D plans and 2D exports — pay per export credit. Trusted across 415,000+ projects.
What is a floor plan app?
A floor plan app is software that lets you draw a scaled layout of a space — walls, doors, windows, and rooms — and produce a shareable plan without manual drafting. AIFloorPlanBuilder runs entirely in the browser: you sketch in 2D with walls that snap into place automatically, AI can rebuild a rough sketch into a clean professional plan, and one click converts the result into an interactive 3D model. Square footage and ANSI-compliant measurements are calculated for you, and there is no subscription if you only need 2D plans and 2D exports.
Everything the app does
Snap-to-place 2D drawing
Walls, doors, and windows align themselves as you click. No CAD training, no fighting with grids or guide lines.
Instant 2D to 3D
One click turns a flat plan into a full three-dimensional model with real wall heights and openings.
AI plan rebuild
Upload a rough sketch, photo, or existing plan and AI reconstructs it as a clean, accurately drawn floor plan.
AI auto-furnishing
Fill rooms with appropriately scaled furniture automatically, or place items yourself from the object library.
First-person walkthrough
Step inside the model and walk the space at eye level to sanity-check flow and sightlines before building.
Unlimited levels
Basements, ground floors, upper stories — each level keeps its own accurate measurements and living-area total.
Automatic square footage
Room areas, wall dimensions, and ANSI-compliant Gross Living Area calculate the moment you draw. Switch imperial and metric anytime.
Export, host, and brand
Download PNG, JPEG, GLB, STL, or OBJ, or publish a hosted 3D link with your own logo and colors, embeddable anywhere.

Frequently asked questions
What is the best floor plan app for beginners?
One where the drawing tools correct you instead of the reverse. AIFloorPlanBuilder snaps walls, doors, and windows into alignment automatically, and its AI rebuild feature can draft an entire plan from a rough sketch, so a first-time user can produce a professional result without any drafting or CAD experience.
Do I need to download or install anything?
No. The app runs entirely in your web browser on Mac, Windows, Chromebook, iPad, and phones. There is no installer, no plugin, and no license key to manage.
Do I have to pay a subscription?
No. If you only use the software for 2D floor plans and 2D exports, you do not have to pay a subscription — you just pay per export credits.
Can the app calculate square footage automatically?
Yes. Room areas, wall dimensions, and ANSI-compliant Gross Living Area are calculated as you draw, on every level of the project. You can toggle between imperial and metric at any time and every figure converts instantly.
Can I turn a 2D floor plan into a 3D model?
Yes, that is the core of the app. A single click converts any 2D plan into a full interactive 3D model with correct wall heights and openings, which you can auto-furnish and then walk through in first person.
What file formats can I export?
Pixel-perfect PNG and JPEG images for 2D plans, plus GLB, STL, and OBJ for 3D models. Every 3D project also gets a hosted, shareable link with an embed code that works on any website.
Is the app suitable for real estate listings?
Yes. Photographers, agents, and appraisers are the most common users. You can produce a branded 2D plan with accurate square footage for the listing sheet and embed an interactive 3D walkthrough on the listing page itself.
