Full Comparison

Criterion	3D AI Studio	Zoo Design Studio
Starting price	Free tier; paid from $20 / month Studio plan billed monthly. Also one-time credit packs from $34, with credits that never expire. Prices in US dollars.	Free plan with 20 minutes of Zookeeper reasoning per month Paid tiers (Plus, Pro, Team, Enterprise) add more reasoning time, around 400 minutes a month on Plus and unlimited on Pro; their amounts are not shown on the public pricing page. Overages run pay-as-you-go at $0.0083 per second.
Free trial	Free tier with complimentary credits, no payment method required	Free plan with full access to Zoo Design Studio and all core CAD workflows
Output	Textured 3D models (text-, image- and sketch-to-3D)	Parametric B-rep CAD models, exported as STEP, STL, glTF, OBJ, PLY or FBX
API	Yes, REST API and an MCP server for Claude, ChatGPT and Cursor	Yes, published developer APIs for building custom CAD applications; Zookeeper runs on the Agent API
Languages	Not stated	Prompts primarily in English, with other major languages accepted at varying accuracy
Hosting	Not stated	Cloud; the desktop application needs an internet connection because the geometry engine runs in the cloud
Made in	Not stated	United States
What it makes	Textured 3D models from text, images or sketches	Parametric B-rep CAD models from text prompts, images and sketches: primitives, brackets, mechanical parts, enclosures, mounts, assemblies and 3D-printable components
Detail and topology	Production-ready models with clean topology, plus remesh and LOD generation	Boundary-representation solids rather than meshes, editable through sketch and feature-tree workflows with human-readable KCL as the source of truth; assembly mates are still on the roadmap
Rigging and textures	AI PBR texturing, with AI rigging and animation tools	No rigging, no animation and no UV-mapped textures: the KCL standard library has no module for any of them. Surface appearance goes as far as setting a material colour on a solid
Speed	From under 90 seconds to a few minutes depending on the model chosen	No fixed generation time is published. Zoo states that Agent API requests, which is what Zookeeper runs on, have no fixed completion time and that the duration depends on the complexity of the task, the tools required and the number of iterations the agent performs; billing follows that, metered in reasoning minutes rather than per model
Export and pipeline fit	Exports GLB, FBX, OBJ, STL, 3MF, USDZ and BLEND for Unity, Unreal and Blender	Exports STEP, STL, glTF, OBJ, PLY and FBX; imports KCL, STL, glTF/GLB, OBJ, FBX, PLY plus experimental STEP/STP and SLDPRT
Commercial use	On paid plans or with a purchased commercial licence, and the licence survives cancellation; without either, the terms allow personal, non-commercial use only	You own the outputs and may use them commercially. Material you put in is licensed back to Zoo to run and improve the service, including training its models, and opting out of that training is possible only on subscription tiers that allow it
MCP-ready	Yes	Yes
Deployment	Cloud (SaaS), Browser-based	Cloud (SaaS), Browser-based
Support	Email helpdesk, Community forum	Email helpdesk, Community forum
Onboarding	Documentation and knowledge base	more entries Documentation and knowledge base, Video tutorials
Company size	Freelancers, Small and mid-sized, Enterprise	Freelancers, Small and mid-sized, Enterprise
Integrations	Unity, Unreal Engine, Blender, Three.js	Not stated

The trade-offs

Strengths and Limitations

3D AI Studio

Strengths

Text-, image- and sketch-to-3D in one tool
Output made on a paid plan is licensed for commercial use, and the licence survives cancellation
REST API and an MCP server for Claude, ChatGPT and Cursor

Limitations

Credit-based costs across the generation tools
Higher-volume use needs the Pro plan or one-time credit packs

Zoo Design Studio

Strengths

Output is editable parametric CAD rather than a mesh that has to be rebuilt
Free plan includes full CAD access plus 20 minutes of Zookeeper reasoning a month
Native applications for Mac, Windows and Linux
The Design Studio application is open source on GitHub
Zookeeper reads selections, renders and existing KCL as context instead of starting from a blank prompt

Limitations

Needs an internet connection: the geometry engine runs in the cloud
Paid tier amounts are not shown on the public pricing page
The geometry engine itself is not open source
Zoo may train on data from free plan usage
Assembly mates are not implemented yet

How we check reviews

Before sending, the author has to confirm three things: that they have used the product themselves, that they work neither for the vendor nor for a competitor, and that nobody is paying them for the review. We also ask whether the vendor invited them to write it. That answer is required, either answer is accepted, and it stays with the review.

Every review is read by a person before it appears. An email address is required and is confirmed: we send a link to it, and a review does not reach us until the author opens that link, so a review has a sender who was reachable at least once rather than being anonymous. Where what somebody writes needs backing, we ask them for evidence that they used the product, and a review that does not get it is not published. We publish positive and negative reviews alike, we pay nothing and offer nothing for a review, and we accept none that was bought or incentivised.

What we cannot do is verify a purchase. There is no shop here and no account, so whether the author really used the tool rests on their own declaration, on whatever we ask them for, and on the plausibility of what they write. We say so rather than implying a check that does not exist.

A vendor cannot buy a review, and cannot have one removed or changed because they dislike it. We remove or edit a review only if it breaks our rules or the law, for example a false statement of fact. Paid placement has no effect on which reviews appear or on any score.
