What is Zookeeper?

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 — 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.

Pros & Cons

✅Pros

•Outputs fully editable parametric CAD models rather than static meshes, so engineers can continue to refine geometry downstream
•Built on Zoo's own high-performance geometry engine, giving the agent direct inspect/snapshot/debug access to the model as it builds
•Runs on Mac, Windows, and Linux natively — unusual for CAD tools, which are often Windows-only
•Free in-browser samples (drill guide, I-beam, cold plate, tooling nest block, robotic arm) let users evaluate before committing
•Enterprise tier supports fine-tuning on proprietary CAD standards, which most text-to-CAD competitors do not offer
•Tuned specifically for real-world manufacturing workflows rather than generic 3D content generation

❌Cons

•Prompt quality strongly affects output — vague prompts produce generic results, as the site's before/after examples explicitly demonstrate
•Output quality depends on how well the target part can be expressed in KCL, which is a narrower representation than full B-Rep history from SolidWorks or CATIA
•Public pricing for individual paid tiers is not clearly published on the Zookeeper page, making budget planning difficult without contacting sales
•Locked into the Zoo Design Studio ecosystem — not a plugin for existing CAD packages like Fusion 360, SolidWorks, or Onshape
•Highly complex assemblies, tolerancing, and GD&T workflows still require human finishing; the agent is best at component-level geometry

Who Should Use Zookeeper?

✓A mechanical engineer rapidly drafting a parametric fixture or tooling nest block by describing dimensions and features in plain English, then refining the editable KCL output in Zoo Design Studio
✓An industrial designer generating early-stage production parts — faceplates, enclosures, anchor plates — with specific dimensions, hole patterns, and feature counts before moving to detailed engineering
✓A small hardware startup without a dedicated CAD specialist producing manufacturable components (drill guides, cold plates, I-beams) by prompting rather than hand-modeling in traditional CAD
✓An enterprise engineering team fine-tuning Zookeeper on their internal component library and design standards so the agent produces parts that conform to company conventions out of the box
✓A researcher or student exploring AI-assisted CAD workflows using the free in-browser samples before committing to Zoo Design Studio or a traditional CAD license
✓A manufacturing engineer iterating on existing designs conversationally — asking the agent to adjust thicknesses, add mounting holes, or scale features — rather than re-editing each parameter manually
