Draw-a-UI with GPT-4 Vision is an innovative application that leverages the power of tldraw and the GPT-4-Vision API to generate HTML from wireframes drawn by users. Aimed at designers and developers, this tool simplifies the process of creating user interfaces by interpreting visual designs and converting them into functional HTML code with Tailwind CSS. The app is built with Next.js 14 and requires Node.js version 18.17 or higher. While the core functionality will remain open source, a hosted version is in development, with a waitlist available at the project’s website. It’s important to note that this app is a demo and not intended for production deployment, as it currently lacks authentication features. To get started, users need an OpenAI API key with access to the GPT-4 Vision API and can run the app locally on http://localhost:3000.
