Modules
Pay for the trades you practise.
Each module is a one-time licence per seat. CLT, Timber frame, Stairs and Roofing build on Timber and need it. Modules run in Foundry today, and come to Kozorosa for Mac with the desktop release that brings them — at no extra cost to those who own them.

Questions
Before you decide.
What happens after the 5 days?
Nothing is charged until you choose. The trial opens every tool and every module; when it ends, pick monthly, yearly or lifetime — or stop, and keep the files you made, which are yours.
Is there a free version?
No. A free tier means deciding which parts of the job to cut out of it, and we would rather give you the whole studio for 5 days than a fraction of it for ever.
What does "lifetime" mean?
One payment, and the application is yours for good — no renewal, nothing that expires. It includes the updates of the major version you bought.
Can I get my models out?
Always. STEP, IGES and BREP for the exact geometry; the Kozorosa document (.k3d) with its whole editable history; mesh formats for everything else. Export is never a paid feature.
Does it work offline?
Kozorosa for Mac does: the geometry kernel, the database and the server run inside the application, and nothing you model leaves your Mac. The AI assistant calls the provider you configure, only when you ask it.
When do Windows and Linux arrive?
The Mac comes first. Windows and Linux builds are in the works; ask to be told when yours is ready. A licence bought for one desktop platform will carry over.
Is there a web version?
Yes, for companies: Foundry runs the web version on your own servers, with accounts, organisations, sharing and the API. It is priced per company — see Foundry.
Is my geometry used to train anything?
No. Your models are yours. AI features call the provider you configure, on the model you choose, when you ask.
Try it on a part you already have.
Import a STEP file, push a face, put a dimension on it. 5 days, every tool, nothing to pay until you decide.
