YTBooks

YTBooks- add chapters and notes to any YouTube video and organize them into folders.

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.
