Best AI CAD is made by the team behind GrandpaCAD, an AI CAD tool for 3D printing. We recommend GrandpaCAD and rank it first on our own published criteria, and every page carries the byline "By the GrandpaCAD team". This page explains who we are and how the rankings work.

How this guide works

How we score every tool

Who we are

GrandpaCAD is made by OTIVIA 32, d.o.o. Vito Meznaric founded it for his grandfather, who prints on a Bambu Lab A1 and doesn't speak English. This site is written by the same team. It isn't an independent review site, a test lab or a publication, and nobody outside the team has checked it.

Why a vendor runs a comparison site

Makers ask "which AI CAD tool should I use?" all the time, and many of the answers we found don't show their method or their sources. We work in this space every day, and we think a comparison that shows its sources and its own tool's limits is more useful than another sales page. It's also marketing for GrandpaCAD. Both are true.

What we do about the bias

  • The ranking is computed from published criteria and weights, and the method page shows the weightings where GrandpaCAD isn't first.
  • Every rival fact links to its source with the date we checked it. Where we couldn't verify something, we say so.
  • GrandpaCAD's limits (paid downloads, no feature tree, sculpted shapes that a height slider only scales as a whole) sit next to its strengths, and our GrandpaCAD page lists everything it doesn't do yet.
  • We name the one case where we'd send you elsewhere: for professional engineers working on complex mechanical parts, Zoo Design Studio is the better pick, and our pages say so.
  • Other tools stay in every table and ranking with their sourced facts, including where they do something GrandpaCAD doesn't.
  • We don't use star ratings, and we don't mark up GrandpaCAD with review or rating data for search engines.

There are no affiliate links. Links to other tools are their plain official URLs, and nobody pays us to be listed or ranked. Links to grandpacad.com carry tracking tags (utm_source=bestaicad) so we can see how many visitors come from here. If you buy GrandpaCAD, the company that makes this site earns the money.

What we haven't tested

We haven't run or printed the other tools' output yet. The comparisons here are built from what each vendor documents. The first-hand evidence on this site is GrandpaCAD's own public example models, which link to the real chats so you can check them. The method page lists the test we plan to run.

Corrections

If we got a fact wrong, especially about a competitor, we want to fix it. Email corrections@bestaicad.com with the page, the fact and a source. We'll correct it, update the check date and log the change in the changes list. Our editorial and corrections policy covers which tools we list and how dates work.
