The #1 AI CAD agent for Text-to-CAD and Image-to-CAD

AI CAD software uses artificial intelligence to automate and enhance the computer-aided design process. BuildCAD AI is a cloud-based web app where an AI agent builds 3D CAD models from your descriptions, lets you tweak them with sliders, and exports STEP files for your favorite desktop CAD tools.

Yes. BuildCAD AI's text-to-CAD feature lets you describe a part or assembly in plain English, and our AI generates production-ready CAD geometry. You can iterate on the design with follow-up instructions, adjust parameters, and export to standard formats like STEP, STL and 3MF.

BuildCAD AI generates parametric, dimensionally accurate models suitable for professional engineering use. All geometry is validated against manufacturing constraints, and you can specify tolerances, material properties, and design standards. Models are fully editable in any major CAD platform.

No. BuildCAD AI runs entirely in your browser. There's nothing to download or install. Your designs are stored in the cloud so you can access them from any device. When you're ready, export to STEP, STL or 3MF for SolidWorks, Fusion 360, Onshape and your slicer.

BuildCAD AI doesn't replace your desktop CAD tools. It accelerates the design phase. Use the AI agent to generate initial concepts 10x faster in the cloud, tweak them with sliders, then export STEP to SolidWorks, Fusion 360 or Onshape for final refinement.

Absolutely. Our models meet professional engineering standards with proper geometric constraints, parametric relationships, and manufacturing-ready output. Teams at aerospace, automotive, and consumer electronics companies use BuildCAD AI in production workflows.

Every design downloads as STEP, STL and 3MF. STEP opens in SolidWorks, Fusion 360, Onshape, FreeCAD and CATIA for further editing; STL and 3MF go straight into your slicer (Bambu Studio, OrcaSlicer, PrusaSlicer, Cura).

Yes. Every new account gets 200 free AI credits to try our built-in agent, no card needed, and the MCP connector lets you design with BuildCAD AI from Claude, Cursor or any MCP-compatible assistant using your own AI subscription, for free. With the built-in agent you pay for what each request uses, typically 30 to 150 credits (1 credit is about 1 cent), and requests that fail on our side are refunded. The Maker plan at $12/month adds 1,200 AI credits every month, Pro at $29/month adds 2,900; plan credits renew monthly. Credit packs start at $5 for 500 credits, never expire and need no subscription.
