## Description

GrandpaCAD is a browser-based AI CAD tool for creating 3D-printable models from natural-language prompts and images. It is aimed at makers, hobbyists, tinkerers, and small teams that want printable geometry without learning a traditional CAD interface.

The service can generate 3D models, expose parameters for later tuning, support model experimentation and reverts, run concurrent generations, add 3D text, use datasheet search for requested specifications, organize models in workspaces, and export 3MF files for printing. Its public roadmap mentions additional export formats such as STL and STEP.

GrandpaCAD is offered as a SaaS product with a free trial allowance, monthly subscription access, and one-time generation credit packs. Public pricing is generation based, with paid packs and subscription quotas plus extra-generation charges.
