From words, to 3D models.

FiveLegFox turns plain language into a structured 3D model in your browser. Real walls, slabs, roofs and doors, not just pictures. No CAD or BIM experience required.

A house modeled in FiveLegFox: walls, windows and rooms shown in 3D on the canvas.

A house takes shape in one minute.

From a few words to an editable 3D model.

Conversation in, structured model out.

Start from an idea, a written brief or an existing IFC file. You get real, editable building elements, not just images.

Some functions are still limited, and errors or inconsistencies may occur. Humans make mistakes too. Sometimes we even put a finger through a door-handle latch opening and try to walk away. Always review and verify the generated model and documentation.

  1. Describe

    Say what to build or change. FiveLegFox interprets the request and asks when something is unclear.

  2. Build

    Specialized agents and deterministic tools create or modify the model. Built-in validation helps catch modeling errors.

  3. Review

    Changes appear on the 3D canvas, ready to review and refine. Save, continue and export when you are happy.

From first walls to finished sheets.

Works in modern browsers and multiple languages. One simple interface: a 3D canvas, a chat and the essential tools.
