AI CAD tools compared: Zoo, Adam and Luxxo CAD.

All three make real CAD geometry that exports to STEP, not the triangle meshes most AI 3D generators produce. They solve different problems, so the right one depends on how you already work.

Which one fits

ZooA complete AI-native CAD application. For engineers who want a new tool to model in, by hand, in code and with an AI agent
AdamAn AI engineer inside your existing CAD, PLM and simulation tools. For teams that mostly edit parts that already exist
Luxxo CADA finished, checked part package from one sentence or a hand sketch. For workshops and engineers who need new parts without installing anything

	Luxxo CAD	Zoo	Adam
What it is	A web app that turns a description or hand sketch into a finished, checked part package	An AI-native CAD application with its own geometry engine and the Zookeeper AI agent built in	An AI engineer that works inside your existing CAD, PLM and simulation tools
Install	None. Runs in the browser	Desktop app for Mac, Windows and Linux, plus a browser version	Web app, connected to the CAD tools you already use
Input	Text, a photo of a hand sketch, or both	Text prompts, images and sketches	Descriptions, plus your existing models, drawings, BOMs and specs
What you get	STEP, STL, DXF flat patterns, A3 drawing PDF and a parts list, with every design	An editable KCL model in Zoo Design Studio; STEP or STL export	Geometry and edits in your own CAD tool; 2D drawings from 3D models
2D drawing	Yes: three A3 sheets with views, sections, hole and weld tables and a measured report	—	Yes, created from your 3D models
Assemblies	Yes, whole mechanisms with standard ISO bearings and screws	Yes; assembly mates are on Zoo’s roadmap	Works with the assemblies in your CAD and PLM
Edit your existing CAD files	No. You take the STEP into your own CAD	Files modelled in Zoo	Yes, through your connected CAD tool
Engineering checks	Solid validity, hole sizes, wall thickness, bearing life, gear undercut, part overlaps, all flagged in plain words	Zoo says Zookeeper cannot guarantee manufacturability or run engineering simulations	DFM checks and a loop to your simulation software
Price	5 designs free, then €9 for 10 designs or €49 a month for 100. Pay per design, no seats	Free plan with an allowance of AI time; paid plans add more. Manual CAD modelling is unlimited	Free plan; paid Pro, Max, team and enterprise plans
Company	Luxxo s. r. o., Bratislava, Slovakia	Zoo Corporation	Adam AI Labs, Inc.

CAD or mesh: check this first

Many tools sold as AI CAD generators return an STL or OBJ mesh: flat triangles that look right but have no true cylinders or planes, so holes and volumes are approximate and the model cannot be edited as CAD. Before you choose any tool, check that it exports STEP. All three tools on this page do.

What Luxxo CAD does not do

The files are STEP, not a native feature tree. Native Creo models are next on the roadmap.
It cannot open and edit a CAD file you already have; it designs new parts and changes its own designs.
Every design is an engineering draft. Complex mechanisms can come back marked “Needs review”, and an engineer should check dimensions, tolerances and materials before anything is made.

Questions

What is the best alternative to Zoo?

It depends on what you use Zoo for. If you want AI inside the CAD tools you already have, look at Adam. If you want a finished part package with a drawing and DXF from one sentence, without learning a CAD tool, try Luxxo CAD.

Which AI CAD tools export STEP?

Zoo, Adam and Luxxo CAD all produce real CAD geometry that exports to STEP. Many text-to-3D tools only export STL or OBJ meshes, which are not editable CAD.

Which AI CAD tool gives a 2D drawing?

Luxxo CAD includes a three-sheet A3 drawing with every design. Adam creates drawings from your 3D models in your CAD tool.
