TexoCAD (https://www.texocad.ai) – you tell it what part you want in plain english (or throw a sketch at it), and it gives you real parametric CAD back. Not a mesh you can't do anything with – actual BREP you can edit and export as STEP, STL, or 3MF.
It runs on build123d under the hood and you can download the generated code too, so you're never locked in – just take the code and keep going in your own setup.
You can also just keep tweaking it by saying stuff like "make it thicker" or "add a hole on the side." Basically trying to kill the gap between having an idea and having something you can prototype.
Would love to hear what you all think, especially if you do anything hardware-related.
