Kororin is a user-friendly Chrome extension designed for individuals new to GitHub, including those without coding experience. This tool allows users to discover random active GitHub repositories by simply clicking an icon and selecting a mode. It offers four distinct modes: 'I'm Feeling Lucky' for general exploration, 'Words' for projects focused on documentation and translations, 'Beginner code' for repositories labeled with good-first-issue tags, and 'Deeper code' for more advanced projects seeking assistance beyond initial pull requests.

Upon landing on a repository, users are presented with a concise card displaying essential project details such as the last update, star count, license type, and relevant topics. Additionally, a 'Roll again' button provides an easy way to discover new projects. Kororin operates without requiring accounts, tokens, or analytics, and is open source under the MIT license, making it accessible for all users.
