Finch3D, an AI and graph technology-based tool, optimizes building designs by providing immediate feedback on performance, detecting errors, and finding optimal solutions in the early stages of design. It includes features such as faster iteration, immediate feedback on designs, built-in error prevention, and sharing of fully interactive 3D models. Use cases include optimizing building design, streamlining the design process, ensuring compliance with rules and regulations, and collaborating with others on design projects. Created by architects, the tool focuses on simplicity, beauty, and functionality.
