LMS Helper is a Chrome extension designed to enhance the functionality of Cosmos LMS, providing users with multiple features aimed at improving the online learning experience. Key features include video playback speed adjustment and multi-video capabilities, allowing users to customize their learning pace. Additionally, it offers shortcut functionalities for quick access to assignments, files, quizzes, and videos, which can be conveniently accessed from the dashboard.

This free add-on is continually updated to ensure compatibility with recognized institutions such as Hallym University, Gangwon University, and Gachon University. Users should note that the extension has a feature that saves video start and end times, which may affect attendance recognition when using playback speed settings. This feature is disabled by default and can be activated in the settings, though the program disclaims any responsibility for outcomes related to its use.
