LearnMark - YouTube Focus & Note-Taking

Capture timestamps, video screenshots, organized tags, and notes seamlessly while studying on YouTube.

LearnMark Pro (formerly TubeFocus & NoteFlow) is the ultimate distraction-free YouTube note-taking & focus extension. Turn YouTube into your personal learning workspace by capturing interactive timestamps, video screenshots, active transcript context, and #tag collections—all synced into a central searchable dashboard. Designed for students, developers, researchers, and lifelong learners who want to build a "Second Brain" directly from YouTube videos. 🚀 WHAT’S NEW IN v2.0 (LearnMark Pro): 🖥️ Central Library & Dashboard: Access a full-screen knowledge hub (dashboard.html) to manage, organize, and search all your saved YouTube lessons and frame captures in one place. 🔍 Global Search Engine: Instantly search across all your saved notes by video title, text content, or specific #tag collections. 📸 Frame Screenshots: Capture exact video frames (code slides, diagrams, formulas) with a single click and attach them directly to your timestamped notes. 🟣 Direct Notion & Obsidian Export: Export your notes with 1-click in natively formatted Markdown optimized for Obsidian (YAML frontmatter, Callouts) and Notion (formatted callouts & metadata). 🏷️ #Tag Collections: Simply type #tags (e.g., #python, #react, #math) inside your notes to automatically group and filter your study material by topic. 💬 Active Transcript Context: Pressing your hotkey captures not just the timestamp, but also the live video subtitle text at that exact second. ✨ KEY FEATURES YOU'LL LOVE: 🎯 One-Click Focus Mode: Hide YouTube comments, recommended sidebar videos, live chats, and distractions so you can focus entirely on studying. ⏱️ Interactive Timestamps (Alt + N): Instantly insert timestamp chips [MM:SS] right where your cursor is. Click any chip to jump straight to that moment in the video. 🖐️ Movable & Draggable Panel: Position the clean, dark-mode notes panel anywhere on your screen for maximum viewing comfort. 💾 Backup & Restore (JSON): Full control over your data. Backup your complete local database (notes, screenshots, tags) or restore it anytime. 🔒 100% Privacy-First & Local: Your notes, screenshots, and data never leave your browser. Stored securely in local storage (chrome.storage.local) with no mandatory account creation or tracking. 💡 PERFECT FOR: • Students taking lecture notes from educational channels. • Developers capturing code snippets & technical diagrams. • Researchers organizing long-form podcasts & tutorials. • Anyone building a Second Brain in Notion or Obsidian.
