Gloss - Learn Languages from YouTube Subtitles & Web

If you learn languages naturally from authentic content—like watching YouTube videos to shadow native speakers or reading foreign articles—Gloss is built to help you capture and organize your personal language knowledge base effortlessly. We believe effective language learning happens when you are fully immersed in content you enjoy, without being constantly interrupted by cognitive overload. That’s why Gloss is designed for frictionless capture: easily select any word, phrase, or sentence you want to learn, get an instant translation, and keep watching or reading. (Save now, study when you're ready.) Every capture automatically preserves its surrounding context and is transformed into structured AI notes in your knowledge base.
