Plan the build before you cut
Workbenches, garage shelving, jigs, outdoor projects — describe it the way you'd explain it to a friend and get a dimensioned 3D model with a parts list. No CAD experience needed.

Brief → plan → model
Describe the object, dimensions, materials, and constraints. The agent turns the brief into editable CAD.
Select → ask → refine
Select the part you mean, ask for a change, and let the agent inspect the updated model.
Prompt2CAD turns a weekend project idea into an adjustable CAD model you can inspect before cutting. Describe a workbench with a miter-saw mount, garage storage shelves, a toy wagon, a raised garden bed, or a mini soccer goal, and the agent plans and builds dimensioned geometry. Specify your stock, such as 12mm plywood, 90×45 treated pine, or 3/4" poplar, then refine naturally: "move the wheels back a bit", "make the top shelf 300mm taller", or "add a lower shelf for the dust collector." Review a geometry-derived parts list with stable IDs, dimensions, quantities, and materials, download it as CSV, or export STEP and DXF for further detailing.
From a brief or existing model to editable CAD
No CAD experience needed. The agent handles the modeling loop while you control the object, dimensions, and final export.
Brief the agent or open a model
Describe the object, upload a reference image, or open an existing DWG, DXF, SKP, OBJ, STL, or GLB model and continue designing from it.
The agent plans and builds
The agent asks for missing details when needed, plans the structure, and uses CAD tools to create real parametric geometry at the dimensions you specified.
Inspect and refine
The agent renders and checks its work from multiple angles. Use controls or say "make it wider" or "add a back panel" to refine the same model.
Share or keep designing
Share a view of your design, review a preliminary parts list, or export STEP, DXF, OBJ, STL, or GLB to continue reviewing and refining it in other tools.
How the CAD agent helps
Describe it like you'd explain to a friend
No CAD experience needed. Say "a workbench 9 feet wide with a miter-saw mount in the center" and the AI builds it. Refine by conversation just like talking through a build.
Real materials and thicknesses
Specify your actual stock — 18mm plywood, 2×4 studs, 90×45 treated pine — and the model uses correct dimensions. No generic placeholder thicknesses.
Parametric adjustments
Change the width, height, shelf count, or leg spacing with sliders. Explore variations instantly without starting a new description.
Preliminary parts list from the model
Review a geometry-derived preliminary cut list with stable IDs, L × W × T dimensions, quantities, and materials. Download CSV for estimating, or export STEP or DXF for further design review.
Built for makers and engineers
From DIY builders and product designers to mechanical engineers, people are using Prompt2CAD to design and iterate on real projects.
"I spent weeks trying other AI and modeling tools for built-in storage in oddly shaped rooms. Prompt2CAD was the first that gave me a precise design I could verify and build from, without needing a CAD background."
DIY home renovator, United States
"I designed a custom L-shaped walk-in closet, 240 by 140 cm, with oak panels, hanging sections, drawers, and recessed lighting. I described the layout in detail and refined the proportions as I went. Saved me a long session in modeling software."
Furniture designer, East Asia
"I needed a custom planter for a terrace with an unusual stepped floor, so the base had to follow an L-shape. I described the geometry, refined a few details, and walked away with something I could actually build from. Much faster than starting from scratch in CAD."
DIY builder, Italy
Brief the CAD agent
Include dimensions, constraints, materials, and intended use when you know them.
Review, share, and keep refining
Review a preliminary list of part IDs, dimensions, quantities, and materials, download it as CSV, or export the model to continue in your CAD and visualization tools. Exports carry the geometry, not a validation of accuracy, fit, or safety.

DeepSeek V4.1 Flash 1017 token rates: $1.20 input / $0.024 cached input / $4.80 output per million tokens. Output includes reasoning. Cache pricing applies only to provider-reported cache hits. Each successful non-zero-token call rounds up to whole credits, with a one-credit minimum.
Illustrative DeepSeek 1017 usage, not measured averages: a new model uses 10 calls of 100k input and 3k output tokens each; an update uses 2 calls of 100k input and 4k output each. Ranges compare 90% input cache hits with no cache hits; the first new-model call is uncached. Output includes reasoning. Actual usage can fall outside these ranges; renders and other AI tools cost extra. Pack counts are either-or examples, not combined allowances or guaranteed completed designs.
Integrating through the API? Generation uses the same account credits and token-based billing. API CAD downloads are unlocked during the trial; web-app CAD downloads unlock after a top-up.
