Text-to-CAD UI - 2026 Pricing, Features, Reviews & Alternatives

Text-to-CAD UI is a cloud-based web application hosted at text-to-cad.zoo.dev that generates fully editable, parametric 3D CAD models from plain-text descriptions. Unlike tools that produce static meshes or point clouds, the platform outputs boundary representation (B-Rep) geometry delivered as STEP, glTF, and STL files, making generated models directly importable into any standard CAD program for further editing. The open-source codebase is built on top of the Zoo ML API, which exposes two endpoints: one for generating 3D B-Rep models from natural language prompts and one for editing existing models. API access is billed per second at $0.50/minute after a free tier, giving developers a programmable path to build custom CAD tooling on the same infrastructure.

Text-to-CAD UI targets a broad range of users across hardware design, mechanical engineering, and manufacturing. Beginners and non-engineers can produce 3D geometry without manual modeling skills, while professional CAD users and hardware design teams can offload low-level CAD execution to accelerate workflows. Enterprise organizations with large CAD operations can fine-tune the underlying ML model on proprietary CAD datasets, aligning generated outputs with internal design standards and conventions. A thumbs up/down feedback mechanism allows users to contribute signal that improves model quality over time.

The platform's open-source architecture gives developers full visibility into the application layer and the flexibility to extend or adapt it for domain-specific use cases. By combining a no-install web interface with a metered API and enterprise fine-tuning options, Text-to-CAD UI addresses the full spectrum from individual exploration to large-scale, organization-wide CAD generation workflows.
