Your smart CAD buddy

Less sketching, more creating.

Describe the part, watch it get built, and learn how it was done.

Early build clip goes here
A real clip of the current build goes here. Nothing polished, nothing staged — when there's something worth showing, it shows up here.

It meets you at your level

Sometimes you want to learn how it's done. Sometimes it's 11pm and you just want the part. Both are fine.

  • Teacher

    Real lessons, inside the program you're actually using. It lights up the button, points the arrow, and coaches while you do it.

  • Mentor

    Say what you want and watch it get built: one-inch square, pad it, hole through the center. You see every step as it happens.

  • Wizard

    In development

    Hand it a photo — build this bracket, these dimensions — and get the printable part back. This is the hard one. It isn't working yet, and I'll show you the day it is.

Get better at FreeCAD, not dependent on it.

The one that started this

You downloaded a part. It's perfect except for one hole that's 3 mm too small. Right now that's either an hour in a program you don't know, or a file you give up on.

∅5.0 ∅8.0
You said make the hole bigger

No menu to hunt through, no constraint solver to fight, no six-hour video. You say what's wrong, and you watch it change.

Why this exists

I'm a hobbyist maker who learned FreeCAD the hard way — bouncing off tutorials, rage-quitting the constraint solver, giving up on parts I could picture but couldn't build.

So I'm building CADWiz: a smart CAD buddy that sits beside FreeCAD, understands plain English, and coaches you through real design instead of doing it in a black box.

How it works

  1. You install two free things

    FreeCAD is a free, open-source 3D modelling program — it's what actually builds and stores your part. CADWiz is an add-on that sits inside it. Both are free, both run on your own computer.

  2. You describe what you want

    Plain sentences, the way you'd say it to someone at the bench. make a bracket 40 mm wide with two M4 holes

  3. It shows you the steps before it runs them

    Yes — there's an AI model doing the translation from your sentence into real modelling operations. Here's exactly what that means: it proposes a list of steps, you read them, and nothing touches your model until you approve. It can't reach your files on its own, and your designs are never sent anywhere to train anything.

  4. You end up with a real model, and you know how it was made

    Not a mesh you can't edit. A proper model with sketches, pads and holes you can open in plain FreeCAD tomorrow and change by hand.

You're in control

  • Your files stay on your machine. CADWiz runs alongside your FreeCAD, on your computer. Your models aren't uploaded anywhere.
  • You approve every operation. Nothing changes your model until you've seen what it's about to do and said yes.
  • Your designs are never used to train anything. Not now, not later, not as a buried settings toggle.
  • It works with FreeCAD, it doesn't replace it. Quit CADWiz tomorrow and everything you learned and everything you built is still yours, in plain FreeCAD.
  • It tells you what it's bad at. The list is right here, written before you had to find out the hard way.

What it's bad at

Written down on purpose, so you can decide before you spend an evening on it.

  • Curved and organic shapes. Brackets, plates, boxes and holes: fine. A sculpted handle or a faired duct: no.
  • Big assemblies. It works on one part at a time. Several parts that have to fit together is beyond it today.
  • Long instructions in one breath. Six changes in one sentence and it will drift. Two at a time works far better.
  • Knowing whether your part is strong enough. It has no idea what load your bracket will see. That judgement is still yours.
  • Being right every time. It gets things wrong, and you'll undo some of its work. Undo is always there, which is why you approve each step.

Tell me what to build

What's the part you gave up on? Or the STL you downloaded that was almost right, if only one hole had been 2 mm bigger?

That question is what shapes the backlog. I read every answer, and the specific, annoying, real ones are worth more to me than any feature list I'd come up with on my own.

Join the waitlist

This list has one job: keep you in the loop as CADWiz gets built and launched. Early-access invites, feature updates, and honest progress from a solo maker — including the parts that don't work yet.

No hype, no sales pitches, and the list costs nothing to join. Just a front-row seat, and a hand in shaping where CADWiz goes.

No spam. Progress updates only, about monthly.

Beta invites go out in waitlist order, and the people who test it early get named in the release notes.
