Agentic AI CAD for custom-built objects
Tell the agent what you want to build.
Get real CAD.
Brief the agent on custom furniture, a built-in, a workshop project, or a part. It plans the model, builds parametric geometry, checks the result, and refines it with you. Tune key dimensions, ask for a cut list, then export real CAD to STEP, DXF, OBJ, or STL — not a polygon-soup mesh.
No CAD experience needed · STEP, DXF, OBJ, STL, GLB, DAE, and PNG exports
Free trial credits included · No credit card required
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.
From a build brief to editable CAD
No CAD experience needed. The agent handles the modeling loop while you control the object, dimensions, and final export.
Brief the CAD agent
Describe the object, dimensions, materials, and constraints — "a fitted wardrobe for a 2.8m alcove" or "a workbench with a central saw bay."
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.
Present or hand off
Review the geometry-derived parts list, download it as CSV, or export STEP, DXF, OBJ, STL, or GLB for downstream CAD, prototyping, and production preparation.
Plan the build
Know every part before you build
Turn the model into a preliminary parts list for estimating and workshop planning. Repeated parts group automatically, hardware stays separate, and every row carries dimensions, quantity, material, and finish.

From idea to a real CAD model
Build custom furniture, built-ins, workshop projects, fixtures, parts, and products with an agent that can reason across the whole model. Get real parametric CAD, a geometry-derived cut list, and exports — not a polygon-soup mesh.
A CAD agent, not a prompt box
Describe what you need in plain language. The agent can clarify the brief, plan the structure, build geometry, and refine it through conversation.
Export to Every Format
STEP and DXF for CAD tools, OBJ and STL for 3D printing, GLB for web viewers, PNG for presentations. Every dimension in real-world millimeters — no unit conversion needed.
Parametric Controls
Every model comes with adjustable parameters — width, height, shelf count, door style. Use sliders and toggles for instant design exploration without starting over.
Cut List & Parts Summary
Open a geometry-derived parts list directly from the model. Matching parts are grouped with stable IDs, L × W × T dimensions, quantities, and materials, then downloadable as CSV for estimating and workshop planning.
Plans, inspects, and corrects
The agent takes screenshots of its work from multiple angles, reads the geometry code, diagnoses visible issues, and corrects the model before handing it back.
Photoreal materials
Walnut grain that runs the right way. Brushed brass that catches light along the grain. Honed marble with real veining. Bouclé that reads as fabric, not paint. The model picks from a curated PBR library of woods, stones, metals, fabrics, leather, and glass — high-resolution CC0 textures from Polyhaven and ambientCG, applied at real-world scale.
AI-Guided Rendering
AI image generators like Nano Banana misinterpret text descriptions and add unwanted details. Feed them your exact 3D model as a reference instead — they follow the geometry precisely, producing accurate renders you can actually use.
New Workflow
Stop wrestling with AI renderers
AI image generators like Nano Banana are powerful but unpredictable — describe "a walnut credenza with sliding doors" and you'll get something that barely resembles what you had in mind. By providing an exact 3D model as a reference, you steer the renderer precisely. Every line, proportion, and detail follows your specification.

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 designed four custom builds in one session, iterating in parallel across all of them. Describing changes and seeing them instantly is what made it click. It replaced hours of redrawing in CAD."
Woodworker, United States
"I designed a custom L-shaped walk-in closet — 240 by 140 cm, oak panels, hanging sections, drawers, 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."
