Illoca, a California-based AI startup, has introduced Plamo, a browser-based agentic 3D modeling workspace designed to convert sketches, reference images, drawings, and natural language into editable parametric geometry. This launch marks a significant step towards making advanced 3D design more intuitive and accessible, particularly for the architecture, engineering, and construction sectors. Plamo is the company's second product, following Tracing Paper, an AI-assisted tool for rapid architectural prototyping.

The core innovation behind Plamo is its 'Agent and Canvas' workflow, which Illoca describes as 'vibe modeling'—a concept akin to 'vibe coding' in software development. Instead of meticulously detailing every parameter, designers can articulate their vision in plain language or through visual inputs. The AI agent then interprets this intent, building the project node by node on a dynamic canvas, allowing users to approve changes, let the agent work autonomously, or intervene at any stage. This approach aims to reduce the manual effort typically associated with 3D modeling.

Traditional CAD software often requires designers to translate abstract ideas into precise, often cumbersome, commands and measurements, leading to a disconnect between creative thought and digital execution. Plamo seeks to bridge this gap by prioritizing the designer's intent, allowing for more fluid exploration of design alternatives. The platform can recreate buildings, combine multiple references, integrate structural or MEP systems, and even reorganize geometry to match project conventions, while also researching missing information or asking for clarification when intent is ambiguous.

Founded by former Autodesk AI Lab, Google DeepMind, and Tesla staff, Chin-Yi Cheng (CEO) and Chiaowei Yu (COO), Illoca brings deep expertise from both generative AI research and practical BIM implementation. Their vision is to free architects and engineers from the laborious task of transcribing ideas into tools, enabling them to focus more on creative problem-solving and iteration. This shift could accelerate project timelines and foster greater collaboration across design and construction teams.

The company previously secured a $13 million seed round in May 2026, led by Bessemer Venture Partners, with participation from AIX Ventures, Root Ventures, and Alt Ventures, signaling strong investor confidence in its AI-native design engine. The beta release of Plamo, which includes 1,000 free credits, positions Illoca to disrupt conventional design workflows by offering a more agile and intelligent alternative that resonates with the evolving demands of the AEC industry.
