YTBooks

Most note tools let you scribble one note on one video. YTBooks turns YouTube into an organized knowledge base — and keeps it in sync everywhere. Perfect for students, researchers, online-course learners, creators, and anyone who learns on YouTube. 📌 Chapters & sections, right in the player Mark a moment as a chapter, or highlight a whole section (a start→end range). Click any chapter to jump straight to that timestamp. No more scrubbing. 🗂️ Study folders across ALL your videos This is the part other extensions miss. Group chapters and notes from many videos into nested folders by subject — a course, a research topic, a content swipe file. Your whole topic in one tree, not scattered across 40 tabs. 📝 Rich notes Real formatting — headings, bold, lists — on each chapter or section, plus standalone notes. A proper notebook, not a single text box. ☁️ Cloud sync & backup (Premium) Your notes on every device, automatically, and backed up online. Crash your laptop, restore in seconds. 📤 Export anywhere One click to Notion or NotebookLM. Feed your curated notes into the AI you choose — on your terms. 🔒 Private by design Your data is yours — we never sell it. Privacy-safe analytics count actions only — never your video titles, chapters, or note content. Premium cloud data is private per-user (row-level security). ——— Free to use: the core — custom chapters, highlighted sections, rich notes, folders, and local file backup — is free. Premium unlocks cloud sync, online backup & restore, higher limits, and Notion/NotebookLM export.
