Never feel lost watching YouTube again
Gloss knows what you don't know and shows explanations on top of the video you are watching.
Don't just watch. Learn.
Gloss picks up on words and ideas you might not know. When they come up in the video, an explanation appears in the top right corner of your screen like a notification—so you don't have to pause and search for it yourself.
Understand Anything Instantly
Quickly explains words, concepts and abbreviations. You'll always know what something means.
Context-Aware Explanations
Gloss understands the video's subject matter. A "cell" means something different in biology vs. programming—Gloss gets it right.
Learning Mode, On Demand
Pause or activate Gloss video analysis anytime with Alt+Shift+G or through the extension icon menu. Switch between learning and leisure mode in a second.
Stay in the Flow
No need to pause videos to Google a term. Stay focused on learning while Gloss quietly handles the research in the background.
Loved by learners
“Instead of having to re-watch long videos that take up too much time, this extension breaks it down for me easy and effectively. This also helped me retain more information from each video, making it easier as a student to learn more in a short amount of time. Overall awesome extension :)”
“I watch a lot of tutorials and tech talks, and most of the time speakers mention a word I don't understand but assume I do, this helps a lot!”
“Learning finance through YouTube was rough. Every video assumed I knew basics I didn't. Gloss fills those gaps automatically. I'm finally keeping up with the content instead of pausing every 2 minutes.”
