AI CAD Design Platform
Free browser-native AI text to CAD

Create editable CAD models from plain Text Prompt.

TextoCAD is a free AI text to CAD generator (up to 4 generations). It turns design prompts into parametric CAD packages with sliders, feature trees, and browser-side model editing. Start with an idea, refine dimensions, and export STEP or STL. Your first 4 generations are free.

Design workflow

TextoCAD focuses on the core product loop: describe, generate, edit, and export your CAD design.

01

Describe

Write a plain-English CAD prompt.

02

Generate

Create an editable parametric CAD package.

03

Edit

Use live sliders and assistant controls.

04

Export

Prepare STEP/STL export workflow.

Frequently asked questions

Is TextoCAD free?

Yes. Your first 4 generations are free after you sign in. You can describe a part, generate an editable CAD model, adjust it with sliders, and export STEP or STL in your browser. After your 4 free generations, paid plans add a more powerful AI model and higher monthly limits, while slider edits and basic STEP or STL export stay free.

What is text to CAD?

Text to CAD turns a plain English description of a part into a 3D CAD model. Instead of drawing geometry by hand, you describe the dimensions and features you need and TextoCAD generates an editable parametric model.

Do I need to install any software?

No. TextoCAD runs in your web browser. There is nothing to download or install, so you can generate and edit CAD models on any modern device.

What file formats can I export?

You can export STEP files for engineering and CAD workflows and STL files for 3D printing. Basic STEP and STL export is free.

Do I need CAD experience to use it?

No. The point of text to CAD is to remove the learning curve of traditional CAD software. If you can describe the part you need, you can generate a starting model and refine it with sliders.
