Create editable CAD models from a plain text prompt.
Describe a part and get an editable parametric CAD package back: dimension sliders, a feature tree, and browser-side editing. Refine it, then export STEP or STL. Your first 2 generations are free after you sign in, and slider edits and exports never cost one.
How it works
Design workflow
Describe the part, generate an editable model, adjust the dimensions with sliders, and export STEP or STL.
Describe
Write a plain-English CAD prompt.
Generate
Create an editable parametric CAD package.
Edit
Adjust dimensions with live sliders and the AI assistant.
Export
Download the model as a STEP or STL file.
Frequently asked questions
Is TextoCAD free?
Yes. Your first 2 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 2 free generations, keep going free with your own AI API key (OpenAI, Claude, Gemini, DeepSeek and more), or connect TextoCAD to Claude or ChatGPT. Slider edits and STEP or STL export are always 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.
