Describeit.Archiebuildsit.
One platform for 3D creation and mechanical CAD, with a local AI copilot at its center. Describe a part below — Archie turns plain language into validated, manufacturable geometry on a real kernel. Open code, open weights, on your own machine.
Open source · free forever · public release soon · native for Apple Silicon · nothing leaves your machine.

Archie is the spine. Studio and Forge are the surfaces it acts on.
ArchDisc unifies creative 3D and precision engineering under a single AI copilot. You don't switch tools — you change intent.
From a sentence to a solid in four moves.
No black box. Archie plans, then emits the exact parametric operations the kernel runs. You can read every call, edit any dimension, and the feature tree stays live.
"A wall-mount bracket, 100 mm wide, two M6 holes 60 mm apart, 4 mm wall, fillet the inside corners." Plain language — no menus, no parameters to hunt for.
The local model resolves intent into named parameters and an ordered feature plan — structured tool-calls you can inspect before anything is drawn.
Archie emits the exact operations the kernel runs — readable, ordered, parametric.
A coherence gate checks the solid — valid topology — and self-corrects if something is off before you ever see it. Then every value becomes editable: change the wall from 4 to 3 and the part re-solves locally. No second prompt.
Other text-to-CAD tools hand you disposable script. Archie hands you an editable feature tree the kernel already validated — and the code that runs it is open.
Open code. Open weights. Yours to run.
- Open code
- Read every line — the kernel, the app, the model harness.
- Open weights
- Archie's per-discipline fleet ships with weights you can run.
- Self-host
- Runs on your own machine. No cloud, no API keys, no lock-in.
- Public release soon
- Pre-release today — star the repo to follow the launch.
Say it. Watch Archie build it.
A local, open-source AI copilot, a real CAD kernel, and a full 3D studio — Studio, Forge, and Archie in one app, on your machine.
