Conversational CAD agent that generates production-ready 3D CAD models from text prompts with research and reasoning capabilities for manufacturing workflows.
Zookeeper is a Design & CAD conversational AI agent that generates production-ready 3D CAD models from natural language prompts, with pricing available as a free in-browser trial and paid access through Zoo Design Studio. It is built for mechanical engineers, industrial designers, and manufacturing teams who want to delegate repetitive modeling, research, and manufacturability tasks to an AI assistant while retaining full control over editable geometry.
Built into Zoo Design Studio and powered by Zoo's high-performance geometry engine, Zookeeper extends the company's earlier Text-to-CAD work with new research and reasoning capabilities. The agent uses engine-level tools to inspect, snapshot, and debug geometry as it works, meaning it can iterate on a design the way a human engineer would â checking dimensions, verifying features, and correcting errors mid-generation. Prompts can range from simple ('a manhole cover') to highly parametric ('a manhole cover with cuts for lifting, 600mm diameter, 50mm thick, with a 200mm hole in the middle'), and the system outputs fully editable KCL (Kitty CAD Language) models rather than static meshes, so designers can continue to refine the geometry in the host CAD environment.
Zoo Design Studio runs natively on Mac, Windows, and Linux, and Zookeeper is also available to try directly in the browser for sample prompts like drill guides, tooling nest blocks, I-beams, cold plates, and robotic arms. Based on our analysis of 870+ AI tools, Zookeeper sits in a small group of genuinely agentic CAD systems â compared to generative design tools that optimize an existing geometry or text-to-mesh systems that produce non-editable assets, Zookeeper's differentiator is that it returns parametric, manufacturable CAD suitable for real engineering workflows. An Enterprise tier adds unlimited Zookeeper credits, SSO, fine-tuning on a team's proprietary designs and standards across CAD formats, and enterprise-grade account management, making it viable for organizations that need to embed AI-assisted CAD into controlled production pipelines.

Unlike single-shot text-to-CAD generators, Zookeeper reasons about the problem before and during generation. It can research part conventions, consider manufacturability, and iterate toward a result rather than returning the first candidate geometry.
Because Zookeeper is built on Zoo's own high-performance geometry engine, the agent has direct access to tools that let it inspect, snapshot, and debug the model as it's constructed. This is what allows it to catch and correct errors mid-generation instead of returning broken geometry.
Zookeeper emits parametric CAD in Zoo's KCL format, so every feature the agent generates remains editable after the fact. Designers can tweak dimensions, change feature counts, or continue the design manually without re-prompting from scratch.
Zoo publishes live in-browser examples for drill guides, tooling nest blocks, I-beams, cold plates, and robotic arms. Users can evaluate the agent on representative engineering parts with no install, which is rare among CAD-grade tools in our directory.
The Enterprise tier lets organizations train Zookeeper on proprietary design data across all supported CAD formats, so the agent conforms to internal standards. It also adds unlimited Zookeeper credits, enterprise-grade security and account management, and SSO for team deployment.

Zoo has evolved its earlier Text-to-CAD product into Zookeeper, a conversational agent with added research and reasoning capabilities and engine-level tools that let it inspect, snapshot, and debug geometry during generation. Zookeeper is now embedded in Zoo Design Studio (available on Mac, Windows, and Linux), and Zoo is running a Makeathon promotion alongside the release.
