Manifesto

The file is the work.

Urbanaut exists because AI for buildings had become a detour. We wanted the agent in the software planners and developers already trust, with the site, the simulations, and the massing in one file.

Why we built it

We were tired of watching people use AI in a weird way. Leave Rhino. Leave SketchUp. Prompt an image that looks like a building. Trace it. Export a mesh nobody can edit. Import it back and discover the plot is a picture, the units are wrong, and the site is gone. That is not a studio. That is a collage.

Architects, planners and developers already have a craft. They already have software they know. They do not need another canvas. They need an agent that shows up inside Rhino 8 and SketchUp, on the file they already own, and stays there.

One place

Site context belongs in the model. Pin a place and bring buildings, roads, terrain and vegetation in as reference, next to the plot, not in a second app.

Simulations belong in the model. Sun, shadow and solar on the geometry you just built, in the same host, on the same file. Environmental studies sit with the massing. They are not a statutory energy model, and we do not pretend they are.

The agent belongs in the model. A structured loop for concept massing, master plans, blocks, plans and sections, details, and the rest of what a CAD agent can honestly do. You describe intent. It proposes geometry. You look at a preview, then you apply or you discard. Undo is a whole construction, not a mystery.

That is the intent. One host. One file. Context, simulation, and the agent in the same place.

The architect is the author

Urbanaut sits in Rhino and SketchUp because that is where the massing already lives. It does not replace the host. It does not hide a second model in the cloud and ask you to re-export.

It is built for concept massing on a real plot: a closed boundary, options inside it, context from a world site, sun and shadow on what you just built. It is not a floor plan that becomes furnished interiors. It is not a 3D model that becomes issue-ready drawing sheets. Those commands exist as guided drafts. They are not certified construction documents.

Honesty

You bring your own API keys. We do not bill your tokens. Roads are not plots. Legal FSI is not invented. The teal ring on a world site is context, not the parcel.
