LeetCat is a free Chrome add-on designed to assist users in solving LeetCode problems by providing minimal yet effective hints. This tool runs entirely offline, ensuring that no user data is collected, which maintains user privacy while enhancing the coding experience. It focuses on guiding users toward understanding optimal time and space complexity, as well as various problem-solving strategies and patterns.

Unlike traditional AI solutions that offer complete answers, LeetCat encourages independence by supplying just enough information to help users identify the right approach without giving away the solution. This fosters skill development and promotes a deeper understanding of algorithmic challenges. With LeetCat, users can think critically and solve problems more effectively.
