What is Gloss?

Gloss is an AI-powered browser extension designed to enhance the learning experience on YouTube by providing real-time definitions and explanations. Developed to solve the problem of viewers getting lost in technical jargon or unfamiliar concepts, the tool displays context-aware notifications directly on top of the video player. It intelligently distinguishes between meanings based on the video's subject matter, such as identifying whether a cell refers to biology or computing. This allows users to stay in their flow without needing to pause and search for terms manually. Gloss is ideal for students, professionals, and lifelong learners who consume educational content, tutorials, or complex lectures. By automating the research process, it helps users retain more information and reduces the cognitive load associated with learning new topics. The extension integrates seamlessly into the YouTube interface, offering a non-intrusive way to bridge knowledge gaps.
