CADlingo
Category: AI in Manufacturing
Browser-based text-to-CAD service that turns natural-language part descriptions into editable parametric 3D models exportable as STEP or STL. CADlingo was founded in 2025. The company is led by Sangmin (Simon) Lee. Based in South Korea. Team size: 1-10. Latest round: Undisclosed.

Value proposition
Users describe a part's purpose, key dimensions and constraints, and CADlingo generates a parametric, manufacturable 3D CAD model in the browser. Users can then edit it through dimension controls or chat and export STEP for downstream CAD work or STL for 3D printing.
Products and solutions
CADlingo 2.0, launched 2026-10-01 (beta). Features: natural-language model generation, parametric dimension editing, chat-based revisions, cross-section inspection, multi-part / assembly modeling with per-part export (e.g., bladed rotating disc, bearing assembly, slider-crank mechanism), clarifying questions when design constraints are ambiguous. Pricing: model generation and STL export are free, STEP export requires a paid plan.
Unique value
Unlike mesh-oriented generative 3D tools, it produces parametric, dimension-driven CAD models. Changing a dimension updates the geometry, and the model exports as editable STEP files that are ready for manufacturing.
Target customer
Founders, product planners, makers and engineers building functional physical prototypes for 3D printing or CNC.
Industries served
Manufacturing, hardware product development, 3D printing / CNC prototyping
Technology advantage
Parametric B-rep style outputs instead of meshes; multi-part assembly generation with separate component export; intent-clarification workflow; runs fully in the browser with no install; freemium model with STEP export behind the paywall.
How they differentiate
Focuses on parametric, editable models built for manufacturing, with multi-part assemblies and per-part STEP/STL export. The workflow is browser-only and chat-driven, and the product is aimed at non-expert founders and product planners rather than professional CAD engineers.
Main competitors
Zoo (Zoo Design Studio / Text-to-CAD, formerly KittyCAD), AdamCAD (YC W25), Leo AI
Major milestones
~Late 2025: initial version released. 2026-10-01: CADlingo 2.0 launched, adding multi-part parametric modeling and separate component export (covered by Platum and StartupRecipe, 2026-10-09).
Market positioning
Early-stage text-to-CAD tool from Korean venture studio WeeklyVentures, positioned to lower the barrier to physical product development.
Geographic focus
Korea-based, with a global English-language web product
