BOJ Chat Service is a Chrome extension designed to enhance communication among users tackling algorithm problems on the BOJ platform. This free add-on enables real-time chat functionality through WebSocket, allowing users to seek immediate help and engage in discussions while working on challenges. Previously, users relied on less interactive methods like forums or messaging apps, which often lacked the immediacy needed for effective problem-solving.

The extension has undergone several updates, improving its usability with features like message editing and deletion, enhanced chat UI visibility, and the ability to convert plain text links into hyperlinks. Future updates are expected to introduce additional communication threads and filtering options to further enrich the user experience. This tool is essential for anyone looking to maximize their learning and collaboration while solving algorithmic problems.
