In this video, Jeff from ‘Getting Started with AI’ demonstrates how to use OpenUI, an open-source tool that allows users to create web components and full pages using AI. OpenUI leverages models like GPT-4o to generate HTML and CSS code based on user prompts. Jeff shows how to build a landing page in seconds by simply describing the desired elements to the AI. The tool can also adapt to feedback, such as adding a navbar or fixing a hamburger menu for mobile views. Jeff highlights the tool’s interface, which includes options to view and convert generated HTML to React, share or download the code, and switch between light and dark modes. He also provides a step-by-step guide on setting up OpenUI locally, including cloning the repository, installing dependencies, and running the application. Jeff emphasizes the potential of OpenUI to streamline web development and encourages viewers to experiment with the tool for their projects.
