One visible step at a time
You describe a project. Atelier works through it with you, and every step stays on screen.
Describe
A brief in your own words becomes a to-do list you can read and change. Nothing is guessed in one go.
Watch
The plan, the model and the files it makes appear as it works.
Stay in charge
Stop it, change the plan or take over the software at any time.

Made for designers
Architects
From a written brief to a first model, plans and a board you can talk a client through.
Interior designers
Plans, moodboards and views kept consistent with one another, room by room.
Students and small practices
A studio assistant that costs nothing to use and runs on a computer you already have.
Free to use and to change, for yourself, your practice and your client work.
From brief to board
- 01
Brief
Your brief becomes a to-do list you can read and change. Nothing is guessed in one go.
12 Oct - 02
Model
With IngeTrazo connected, the house is modelled step by step and stays visible while it is built.
12 Oct - 03
Drawings
Plans and elevations drawn as vector linework from the model: measured, to scale, and printable at any size. The geometry never moves.
Later - 04
Renders
Exterior and interior views made from the same model, so they agree with the drawings.
Later - 05
Wind
When you ask, a wind study laid over the model so you can see how air moves around the building. Early design guidance, not engineering.
Later - 06
Board and web page
Drawings, views and materials composed into a vector presentation board and a web page you can share.
Later
One graphics card. Your office.
On your own computer
Atelier runs as a web app on your machine, with the model on your own graphics card, so nothing has to leave your office. We build and test it on one 32 GB Intel Arc Pro B70 running a 27B vision model.
Through the cloud
No suitable graphics card? Point Atelier at a cloud model instead: OmniRoute’s free tiers, or your own API keys. Your prompts and images then go to that provider, so choose it as you would any other service.
Any model you like
Atelier does not include or require a particular model. Connect one through any OpenAI-compatible endpoint (it is tuned for Holo-style models), and change it at any time without changing how you work.
Atelier ships no model. Connect the one you prefer, and change it whenever you like.
Model it live
With IngeTrazo connected, the house is modelled step by step, and the model stays on screen while it is built.
The modeller
IngeTrazo is the open-source push/pull architecture modeller by Marco Sumari Tellez and contributors (GPL-3.0-or-later).
Installed separately
Atelier never bundles it. When IngeTrazo is not running, Vitruvius says how to turn it on and keeps working on the canvas.
On 12 October
The connector ships with the preview. A native panel for IngeTrazo is a separate GPL download.

To scale, in vector
Every line measured, printable at any scale.
Plans, elevations and boards are drawn as vector linework from the model, never made as pictures. They follow the preview.
LaterVector sheets drawn from the model: every line measured, printable at any scale. The first boards are being drawn now and will be published here.

From an image to a 3D model
A piece starts as a design image and becomes a 3D model with the same proportions and finish.
Studio work · not in the 12 Oct previewDesign images: Qwen-Image via ComfyUI. 3D models made from them on our own computers.






Placed at real size
Each piece goes into the room at its true size, to be judged against the walls, the light and the way through.
54 pieces across seven rooms (living, dining, kitchen, bedroom, office, terrace and bath), placed without a single clash.
Studio work · not in the 12 Oct preview
Getting the geometry right
A model made straight from an image can look right and still be wrong: bowed panels, soft corners, drawers that do not line up. Where a piece is made of boards, we rebuild it from measured parts, so the drawers sit in true gaps and the legs stand straight.



What ships, what follows
12 OctIn the public preview
- Atelier itself: the web app that runs on your own computer, and its source.
- Vitruvius and Vitruvius Zero: design help, concept plans on a canvas, material and colour moodboards.
- The stock profiles from DeepSeek Harness alongside.
- The IngeTrazo connector, with IngeTrazo installed separately.
- Moodboard images through your own image service, if you have one.
- README, quick-start, setup walkthrough, credits and the licence.
LaterOnce each piece is proven
- Vector drawings and boards to scale.
- Renders, wind studies and a web page for each project.
- The image-to-3D studio work.
- Voice, and Atelier on a tablet.
- Plugin uploads, Trazo Fabrication first.
In plain words
Source-available, under PolyForm Shield 1.0.0.
Atelier is released under the PolyForm Shield 1.0.0 licence. In plain words: it is free to use and to change, for yourself, your practice and your client work. What it does not allow is reselling Atelier, or using it to build a product that competes with it. The full text ships with the source.
What stays as it was
DeepSeek Harness stays MIT. The IngeTrazo panel stays GPL-3.0-or-later. Our terms cover only what we added.
Your model, your terms
Every model you connect keeps its own licence. Check it fits how you work.
