Twelve things the Fox does: try them yourself.

In action

What is FiveLegFox?

3D architectural modeling in the browser, through conversation.
No installation: it runs in any modern browser.
A simple interface: 3D canvas, chat, essential tools.
Start from an idea, a brief or an IFC file.
An LLM reads your requests, subagents do the modeling.
You get structured, editable 3D models, not just images.
No CAD or BIM skills needed; your projects stay yours.

What can you do?

Model

Walls, rooms, slabs, roofs, doors, windows, furniture.
Edit

Move, resize, rotate, copy, color or remove.
Furnish

Place objects from the library and adapt them.
Document

Sheets, dimensions, annotations, drawing scale and room schedules in Paper Space.
Sections and views

Horizontal and vertical sections with accurate 2D drawings.

How does it work?

Describe what you want to create or change.
The LLM interprets your request and asks when something is unclear.
Specialized subagents and deterministic tools build the model.
Changes appear on the 3D canvas, ready to review.
Built-in validation helps catch modeling errors.
FiveLegFox is in beta with about 100 testers, and some functions are still limited. Humans make mistakes too: always review the generated model.
