Features
From a sentence to a drawing you can build from.
Describe what you want to build. Your AI architect designs one precise, editable floor plan, renders it, and refines it with you — all on one infinite canvas.
01
Your AI architect
Describe a brief in plain language. It asks the questions a good architect would, then writes readable source — rooms, program, and circulation — not a pile of pixels. That source compiles to the drawing on the right, and it revises as you steer.

02
Editable plans with real dimensions
Every plan is a precise, editable drawing — real millimetre walls, doors, and windows, not a raster guess that drifts each time you regenerate. Underneath sits ArchLang, an open floor-plan language: readable source that recompiles to exactly the same drawing, every time. Hover a line and its room lights up.
Courtyard Apartment
A two-bed flat wrapped around a daylit central court.

Renderings grounded in the plan
Ask for a rendering and you get a photoreal view built from the real floor plan — the same walls, the same light. It’s something you can put in front of a client without leaving the canvas.
04
One infinite canvas
Pan and zoom across an endless workspace. Lay a design and its iterations side by side, compare them at a glance, and branch a new direction from whichever one holds up.
05
Export to the tools your builder uses
Your design isn’t trapped in the app. The same source — declared in real millimetres — exports to a DXF that opens cleanly in AutoCAD, ARCHICAD, and every serious CAD tool, or to PDF for a review set, PNG and SVG for the web.

Share a link, no account needed
Hand anyone a public, read-only link to the canvas. They pan, zoom, and explore every version in the browser — no account, no install, nothing to download.
Bring the brief. Leave with the drawings.
