For more than seven years, UpCodes has been making the complicated world of building codes easier for people like industry professionals and homeowners to understand. Its platform includes a searchable database covering regulations in all states and features like a “spellcheck” that flags code errors for architects. Today, the startup is announcing a new AI-based tool that will make navigating the world of building codes even more streamlined. Called Copilot and built on ChatGPT-4, Copilot serves as a research assistant, answering complicated code questions and annotating responses with links to relevant sections of code.
