Lumina v3.0 — Focus Mode for YouTube
🛑 Stop the Doom-Scroll. Start the Deep Work.
The YouTube algorithm isn't broken; it's working exactly as designed—to hijack your attention. You log on for a 10-minute coding tutorial, and hours later, you're deep in a rabbit hole of endless Shorts.
Lumina fights back. We don't just block distractions; we transform YouTube into a dedicated, distraction-free learning environment. Welcome to the Zen Architecture.
🚀 Introducing v3.0: The Zen Architecture Update
We completely rebuilt Lumina from the ground up to be faster, smarter, and beautifully immersive. Join the students who maintain a 100% focus retention rate using our latest tools:
Smart Note Stacks: Your notes are now intelligently auto-organized by Video ID and Channel. Build a pristine library for your specific courses, rather than a messy, endless wall of text.
Ambient Glassmorphism 2.0: A premium, minimalist UI that dynamically samples colors from your video, creating a subtle, immersive "breathing" glow that matches your content.
Focus Score: A real-time, gamified attention tracker that rewards you for staying on task.
Zero-Flicker Performance: Our new debounced observer engine ensures the transition into 'Zen Mode' is buttery smooth, eliminating screen flash entirely.
Eco-Engine (GPU-Optimized): We don't just hide the algorithmic sidebar; we physically stop the browser from rendering it. Our Repaint Suppression technology saves laptop battery life and CPU/GPU cycles during long study sessions.
✨ Core Capabilities
The Distraction Shield: Instantly vaporize YouTube's psychological "hooks," including Sidebar Recommendations, Comments, Live Chat, Shorts, and the clickbait Homepage Feed.
The Floating Study Notepad: A professional, draggable, and resizable note-taking canvas injected right over the video player. Never switch tabs (and risk losing focus) again.
One-Click Timestamps: Hit "+ Time" to instantly drop the current video timestamp (e.g.,) into your notes for seamless review later.
Universal Export: Download your study session as a clean .txt file ready to be dropped straight into Notion, Obsidian, or Google Docs.
🔒 Privacy First. Always.
Your focus is your business. Lumina operates with strict data isolation.
Zero Data Collection: We never track your searches, watch history, or focus metrics.
100% Local Storage: Your Smart Note Stacks and Focus Scores live securely on your own device. No cloud, no servers, no accounts required.
⚙️ Technical Specs
Ultra-Lightweight: Engineered to be practically invisible at under 100KB.
Modern Security: Fully optimized for Chrome's latest and most secure Manifest V3 standards.
Reclaim your attention span.
Add Lumina to Chrome today and turn YouTube into the ultimate e-learning platform.
