Vochay
Design.

Architecture at the Speed of AI.

The AI that drives architects' existing software.
Natural language in. Editable 3D model out.
For the architect who designs — not the one who clicks.

The Prompt

“Generate a modern two-story residential house, with a double front porch.”

→ Native BIM in Archicad.

What BIM Is

BIM (Building Information Modeling) is 3D software used by architects to build to-scale models containing 3D geometry, real-world dimensions, materials, and construction data.

01 · The Problem

They automated the factory.

We're still clicking the drawings.

Every rendering farm, every CNC router, every modular factory — all highly automated systems fed by outdated input methods designed in the 1990s. Archicad. Revit. Vectorworks. The standards of the industry, still operating on cockpit-style interfaces built for operators, not designers. The principal architect — the one with the thirty years of industry knowledge and experience — has always needed a human intermediary to translate design intent into the software. Vochay revolutionizes that process. The architect speaks. The software delivers the results.

1990s

UI paradigm still shipping in every major BIM suite, while the rest of construction has moved to robotic fabrication and photorealistic cloud rendering.

"Can we make the building ten feet wider?"
— The eight words that rebuild an entire 3D model by hand. SD and DD are the most valuable phases — and the most inefficient. One change cascades through the entire model, to be manually updated piece by piece.
02 · The Product

Natural language in.
Native BIM out.

We don't generate pictures of buildings. We generate the 3D building data itself, inside the architect's existing licensed BIM software.

04 · The Competition

Everyone else is solving the wrong layer.

Five categories, only one of them focused on removing the inefficiency and tedium of architectural BIM software.

The exact triad.

Domain authority. Technical expertise. Systems integration. All three are required.

SF
Stephanie Ferrell, FAIA
Founder & Principal Architect
Project Visioning and Forward Guidance

A practicing architect specializing in urban development and Fellow of the American Institute of Architects, Stephanie is the vision behind Vochay: she identified the problem it exists to solve, assembled the team to solve it, and helps keeps the product true to how design actually works. She has always practiced the way many principals do — envisioning the project and directing the design, never drafting it — which makes her exactly who Vochay is built for. That vision runs all the way into the product: four decades of practice, encoded into Vochay as it helps the architect create, visualize, and realize what they design.

CS
Christopher Stringer
BIM Specialist & Educator
Certified Archicad trainer · GDL scripting

BIM specialist with deep proficiency across Archicad, Revit, SketchUp, and architectural animation software. Chris has provided Archicad training & support at a professional level, and brings rare technical depth to the team. He is an expert in GDL, Archicad's own parametric 3D object scripting language, giving him programming-level insight into how BIM geometry is constructed from the inside. His reference project and training methodology define the standard of correctness Vochay is built to meet.

Software Development & Engineering
Built the AI → BIM engine & Architect Agent

Vochay Design's lead engineer. Built and manages the MCP bridge connecting the AI orchestrator directly to the core engines of Archicad, Revit, and the rest of the industry's BIM software, the Architect Agent guardrail layer, and codified the skills of the rest of the team into usable intelligence. Ensures every placed element is valid against architecture rules and safely auto-corrects what it can — every fix independently reversible, even across sessions. Proved the pipeline's fidelity by rebuilding a real production project element-by-element: walls, terrain, and railings reproduced down to exact material thickness and hardware geometry, not just approximate shapes.
