Add Axle to
your AI.
Your ChatGPT or Claude subscription already knows how to talk to Axle Keys. Paste one URL, sign in, approve — and your AI can design real parametric CAD: models it briefs, builds, validates, and hands you back as something you can configure and fabricate. No installs. No API keys.

Skills your agent can learn.
Connecting gives your agent the tools. A skill teaches it the workflow — which tools to reach for, in what order, and what a finished job looks like. They're free, MIT-licensed, and they live in the open on GitHub.
Describe a part in plain English and get a real parametric model back — built, measured against the dimensions you asked for, and shown to you. Not a mesh and not a screenshot: something with named parameters you can still change afterwards.
Then watch it work.
Everything your AI does lands in your workspace: the brief in your own words, every code push, every build result and validation verdict. Open Studio and the Session Activity pane shows the work live while you type in your AI app — the models are yours to configure, render, and take to fabrication.
