Zoo Design Studio

Zoo Design Studio is an emerging CAD platform built around AI-assisted mechanical design. Developed by KittyCAD, the platform allows engineers to generate editable CAD models using natural language, code, or traditional modeling tools.

Unlike conventional CAD systems where every feature must be manually modeled, Zoo introduces an AI design assistant called Zookeeper. Engineers can describe a part in plain language, and the system interprets the intent, plans the modeling steps, and generates the geometry automatically.

The generated models are B-Rep CAD geometry, meaning they remain fully editable and compatible with real engineering workflows such as simulation, CNC machining, and manufacturing.

Zoo also supports traditional workflows. Engineers can still model parts using familiar operations such as extrude, revolve, and boolean operations, while optionally combining them with AI or programmable workflows.

Because of this hybrid approach, Zoo is attracting attention from engineers exploring AI-assisted design, programmable CAD pipelines, and rapid prototyping workflows.

Key Features

• Zookeeper AI design agent for text-to-CAD geometry generation from natural language prompts
• B-Rep output geometry that remains fully editable and compatible with simulation, CNC, and manufacturing workflows
• Traditional CAD operations including extrude, revolve, sweep, and boolean for conventional modeling alongside AI workflows
• KCL (KittyCAD Language) for programmable, code-driven CAD geometry definition
• API access for building custom engineering tools and automated design pipelines on top of the Zoo geometry engine
• GPU-native geometry engine built for modern hardware without legacy architectural constraints
• Open-source application layer for community transparency and extensibility
• Cloud-based geometry processing with version control infrastructure for design history management

Best For

Forward-thinking mechanical engineers, hardware startups, and engineering teams frustrated by legacy CAD infrastructure who want AI-native design tools, Git-based version control, and a modern geometry engine that doesn't carry 40 years of technical debt.

Particularly relevant for teams building internal engineering tools, automated part generation pipelines, or rapid concept generation workflows where conversational design intent input is more efficient than manual feature modeling.

Who It’s Not For

Teams that need the deep, battle-tested feature sets of SolidWorks, NX, or CATIA today. Zoo is still maturing in areas such as large assembly management, advanced surface modeling, GD&T, and simulation integration. It is also not suitable for engineers who require fully offline workflows, since geometry processing runs in the cloud and requires an internet connection.

Platform

• Windows, macOS, and Linux desktop application.
• Web browser test environment available but not recommended for production use.
• Internet connection required for all geometry processing, which runs in the cloud.

Pricing

Freemium.

• Free tier includes 20 minutes of Zookeeper reasoning time.
• Paid tiers unlock unlimited Zookeeper credits, team collaboration, and enterprise features.
• Enterprise pricing available with custom AI model training on proprietary CAD datasets. Contact Zoo directly for enterprise quotes.

Pros

• Only CAD tool with a conversational AI agent operating at the geometry engine level, producing editable B-Rep output rather than mesh or image approximations
• KCL programmable CAD opens up automated geometry pipelines and custom internal tooling that traditional CAD scripting environments do not support cleanly
• GPU-native geometry engine built for modern hardware from the ground up
• Open-source application layer makes the codebase transparent and community-auditable
• Git-compatible version control for CAD files makes collaborative and branching design workflows practical for the first time in a mainstream-accessible tool

Cons

• Early-stage product with feature depth that does not yet match established CAD tools in areas such as large assemblies, advanced surfacing, and manufacturing documentation
• Zookeeper reasoning time is metered even on paid plans, adding a consumption dimension to the design workflow
• Smaller ecosystem, community, and learning resource library than any mainstream CAD platform
• Not yet proven at enterprise assembly scale or in regulated engineering environments with formal validation requirements

Rating

⭐ 4.1 / 5

Editorial Take

Zoo represents a new experimental direction for CAD where design intent can be expressed through prompts or code. While still early compared to traditional engineering tools, it offers an interesting glimpse into how AI could reshape mechanical design workflows.
