FloorGen

Product Introduction

1. Definition: FloorGen is a browser-based, AI-assisted floor plan and 3D modeling software-as-a-service (SaaS) application. It functions as a technical design tool for creating, editing, analyzing, and visualizing architectural floor plans directly in a web browser without installation.
2. Core Value Proposition: It exists to democratize architectural planning by providing a free, professional-grade tool that instantly converts textual descriptions or sketches into editable, code-compliant 2D plans and 3D walkthroughs. Its primary value lies in its no-signup, free access model, integrated AI floor plan generation, and automated building code compliance checks against major international standards like the IRC and NBC.

Main Features

1. AI-Powered Plan Generation & Editing: Users can describe a room, ADU, or house in plain language, and FloorGen's AI engine generates a corresponding, editable floor plan. This extends to its MCP (Model Context Protocol) server, which exposes 149 tools, allowing external AI assistants like Claude and ChatGPT to read and modify the actual vector-based drawing data, with every change recorded as a reversible undo step.
2. Automated Building Code Compliance Review: The software integrates pre-configured code profiles (IRC, NBC, OBC, UK Approved Documents, DIN, CDMX). It automatically analyzes the drawing in real-time, flagging violations such as undersized habitable rooms, non-compliant stair dimensions, or insufficient headroom. Each issue is annotated on the plan with the specific code section (e.g., IRC R304.2) and a description.
3. Integrated 2D-to-3D Pipeline & Export Suite: Every 2D plan is simultaneously a 3D model. Users can furnish spaces from a library of ~3,000 categorized models, apply wall and floor finishes, and generate orbitable dollhouse views or first-person walkthroughs. The export functionality is comprehensive, producing scaled PDF plan sets with title blocks, high-resolution PNGs (up to 4,500px), DXF (R12) files for CAD interoperability, glTF 3D models, and MP4/WebM walkthrough videos up to 1440p resolution.

Problems Solved

1. Pain Point: The high cost, complexity, and steep learning curve of traditional architectural CAD/BIM software (e.g., AutoCAD, Revit) creates a barrier for non-professionals and small-scale projects. Furthermore, manually checking plans for building code compliance is time-consuming and error-prone.
2. Target Audience: Homeowners and Renters planning renovations; Interior Designers and Architects needing quick client visualizations; Real Estate Agents and Builders/Contractors creating proposal and marketing materials; Educators teaching design fundamentals; and AI Power Users who want to integrate spatial planning into automated workflows.
3. Use Cases: Remodel Planning: Testing furniture layouts in an existing room before purchasing. ADU/Home Design: Creating a permit-ready plan set for a backyard unit or new home, complete with code review. Real Estate Listing Enhancement: Generating 3D walkthrough videos and furnished plans from existing blueprints. Design Collaboration: Sharing a view-only HTML file with clients for feedback. AI-Assisted Design: Using a chat interface to iteratively refine a floor plan based on textual feedback.

Unique Advantages

1. Strengths & Limitations (Pros & Cons):

   • Pros: Completely free with no watermarks, project caps, or trial limitations. Exceptional accessibility with no installation and browser-based operation across devices. Unique AI integration via both a built-in chat and standardized MCP for external assistants. Powerful, automated code-checking feature rare in consumer-grade tools. Robust export options, including DXF for professional workflows.
   • Cons: Lacks photorealistic rendering capabilities. Exports are limited to DXF (R12) and cannot import DXF/DWG, limiting two-way CAD workflow. No support for complex MEP (Mechanical, Electrical, Plumbing) systems or detailed framing takeoffs. The AI wall detection from images is semi-automatic, requiring user verification.

2. Key Alternatives & Differentiation:

   • SketchUp Free / Planner 5D: These are more general 3D modeling or interior design tools. FloorGen differentiates by being purpose-built for architectural floor planning first, with built-in scale, real-world building codes, and professional drawing set exports (PDF with title block), which alternatives lack.
   • Chief Architect / AutoCAD LT: These are industry-standard professional software costing hundreds to thousands of dollars. FloorGen is functionally a free, simplified, and web-based alternative that sacrifices advanced detailing and customization for extreme accessibility and AI features.
   • MagicPlan / RoomScan Pro: These mobile apps focus on room measurement via AR/camera. FloorGen is a full-featured design studio with more advanced editing, furnishing, code analysis, and export versatility, though it requires manual input or image tracing for existing spaces.

Frequently Asked Questions (FAQ)

1. Is FloorGen really free for professional use? Yes, FloorGen is completely free, including all core features: the editor, 3D modeling, walkthrough video generation, building code checks, and exports (PDF, PNG, DXF, glTF). There are no watermarks, project limits, or trials. A free account is only required to enable cloud sync and the built-in AI chat.
2. How accurate are the AI-generated floor plans and building code checks? The AI generation provides a strong starting layout based on the description but should be reviewed and refined by the user. The code checks are based on standardized profiles (IRC, NBC, etc.) and are highly accurate for the rules they cover (room sizes, stairs, egress). However, they are a design aid only; local amendments and final authority always rest with the local building department for permit approval.
3. Can I import my existing AutoCAD DWG files into FloorGen? No, FloorGen does not support importing DWG or DXF files. You can import an image (PNG, JPG) or PDF of a plan, set the scale manually, and trace over it or use the semi-automatic wall detection tool to recreate the plan within FloorGen.
4. What is the difference between using the built-in FloorGen AI and connecting Claude via MCP? The built-in AI (Ctrl+I) is a convenient chat interface within the editor. The MCP server connection provides the same underlying 149 tools to external AI assistants, enabling more complex, programmable workflows within tools like Cursor or Claude Desktop. Both methods edit the real drawing with full undo capability.
5. What are the limitations of the free DXF export? FloorGen exports to the DXF R12 format, a widely compatible standard. Each object type (walls, doors, dimensions) is placed on a separate layer for easier editing in CAD software like AutoCAD. The key limitation is that this is an export-only feature; you cannot import or edit a DXF file back into FloorGen.
