LeetMask is a Chrome extension designed to enhance your LeetCode experience by hiding the difficulty tags of problems and preventing access to any LeetCode profiles, including your own. The extension aims to improve your performance by replacing difficulty tags with a '' emoji, helping you approach problems without preconceived notions. By concealing difficulty levels, LeetMask encourages a bias-free problem-solving approach akin to real interview scenarios.

Moreover, LeetMask discourages a fixation on points and achievements, emphasizing the enjoyment of the game itself. By deterring users from focusing solely on badges, contest ratings, or problem-solving metrics, the extension promotes a more immersive and fulfilling LeetCode experience. It aims to prevent users from feeling complacent after hitting milestones or comparing their progress with others, fostering a healthier and more focused mindset.
