About YouTube Learning AI: Context & Definitions - Gloss

Stop pausing to Google things. Understand every YouTube video instantly. Gloss is your YouTube AI copilot for learning. It automatically detects complex terms, slang, and technical concepts, overlaying clear definitions right on the video. Perfect for students, developers, and lifelong learners who want to stay in the flow. 🚀 TOP FEATURES ✅ Instant AI Definitions Get clear explanations for technical jargon, acronyms, and cultural references without leaving YouTube. ✅ Context-Aware Intelligence Gloss knows the difference. A "tree" in a coding tutorial is different from a "tree" in a biology documentary. Our AI adapts to the video context. ✅ Seamless Learning Mode Toggle analysis on/off with Alt+Shift+G. Turn YouTube into an active learning platform when you need it, and sit back when you don't. ✅ Focus & Flow Eliminate the "tab switching tax." Keep your attention on the lecture or tutorial while Gloss handles the research in the background. 🎯 PERFECT FOR 🎓 Students: Crush lectures and Khan Academy videos without getting stuck on new vocab. 💻 Developers: Understand new frameworks and docs by getting instant context on coding terms. 🌍 Language Learners: Master idioms and cultural references that dictionaries miss. 🧠 Lifelong Learners: Deep dive into finance, science, or history with an AI tutor by your side. 🔒 PRIVACY & TRUST We believe in privacy first. Gloss analyzes video text to provide definitions but does not sell your personal browsing data. Free to start (Generous free tier) 7-day money-back guarantee on Pro plans 📧 CONTACT & SUPPORT Need help? Reach us at support@retrove.net
