Unsolved Hunter is a free Chrome add-on designed to assist users in efficiently selecting unsolved problems from the Baekjoon Online Judge (BOJ) platform. This tool offers features for both individual users and groups, allowing them to quickly access problems that have not yet been solved by any member. The add-on streamlines the process of finding relevant problems based on user-defined criteria, enhancing the problem-solving experience.

For group users, Unsolved Hunter allows the registration of all members via the group ranking tab, enabling automatic problem registration based on specified tiers and quantities. Individual users can select their desired tier from the "Today's Problem" tab, leading them to a curated list of problems. Recent updates have addressed issues related to dropdown functionality on smaller screens and log-in status, ensuring a smoother user experience.
