From idea to parametric CAD.
In minutes.
Describe what you want to build in plain language — "a Japandi wardrobe wall, 3.2m wide, three modules" — and get a real parametric 3D model in seconds. Tune dimensions with sliders or conversation, then export to STEP, DXF, OBJ, or STL. One tab takes you from idea to CAD export — no round-trips between tools.

From idea to 3D model in minutes
No CAD experience needed. Just describe what you want.
Describe Your Design
Type a natural language description — "a standing desk with cable management," "a Japandi-style room divider," or "a display tray with five product pockets."
AI Generates the Model
The AI creates parametric geometry code, renders it live in 3D, and verifies the result by taking screenshots from multiple angles — iterating until it looks right.
Refine & Adjust
Use parametric sliders to tweak dimensions, shelf count, or toggle features. Or just say "make it wider" or "add a back panel" — the model updates instantly.
Render & Export
Photoreal viewport with real wood grain, marble veining, brushed metal, and fabric weave — pulled from a curated CC0 PBR library. Then export as STEP, DXF, OBJ, STL, or GLB for your CAD workflow, 3D printing, or web. All in one workflow.
From idea to a real parametric model
Describe it. Refine it. Render it. Export it. Real CAD geometry — not a polygon-soup mesh — generated, edited, and rendered in one browser session.
Conversational Design
Describe what you want in plain language. Refine through natural conversation — "make the shelves thicker" or "add a drawer at the bottom."
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.
Self-Verifying AI
The AI takes screenshots of its own work from multiple angles and iterates until the model looks right. It reads the geometry code, diagnoses issues, and fixes them automatically.
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.
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 the people who design and build
DIY Home Builders
Know what you want to build — a workbench, a toy wagon, a soccer goal — and need to visualize and dimension it before cutting. Describe the build the way you'd explain it to a friend, and export a plan you can actually build from. No CAD experience needed.
Custom Wardrobe & Storage Specifiers
Homeowners fitting a real room, or small joinery operators designing for a client. Start with the room — wall heights, ceiling slopes, window positions — and work inward to the furniture. The output is a brief for a carpenter or a cut list.
Product & Retail Display Designers
Model objects for physical manufacture — display trays, counter fixtures, product stands. Run multiple variants in parallel and need clean STEP exports for 3D printing or CNC. Speed and export quality are what matter.
Mechanical Engineers & Hardware Developers
Design functional parts — brackets, enclosures, assemblies — through iterative refinement. Describe spatial and mechanical relationships in natural language and converge on a geometry through conversation, often over hundreds of iterations.
Bespoke Furniture & Object Designers
Small studios working on one-off pieces for clients, with strong material and finish intent. Use Prompt2CAD for rapid concept modeling before committing to a full technical drawing.
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."
