ChapterJump – Chapters, Timestamps & Bookmarks for YouTube

Jump to any chapter of a YouTube video from a floating, searchable list. Save timestamp bookmarks. Private, free, no sign-up.

ChapterJump puts every chapter of a YouTube video in a floating list right next to the player. See all chapters and timestamps at a glance, search them as you type and jump to the exact moment in one click, without scrolling the description or scrubbing the progress bar. Stop scrubbing. Jump to the chapter. Made for long videos: lectures, online courses, coding tutorials, podcasts, interviews, recipes, workouts and livestream replays. ✨ WHAT YOU GET • Chapter list — thumbnails and timestamps, with the current chapter highlighted and followed as you watch • Instant search — type a word and the list filters as you type. Ctrl+Shift+F (⌘⇧F on Mac) opens it from anywhere • Timestamp bookmarks — save any moment with one click and give it a name. Works even on videos without chapters • Links to the second — copy a link that opens the video at a chapter or bookmark • Your layout — drag, resize or collapse the panel. The position is remembered across tabs • Fits in — light and dark themes follow YouTube, and the panel stays visible in theater mode and fullscreen • Finds chapters in the chapter list, in timestamps from the description or in the progress bar 🚀 PRO — FREE DURING EARLY ACCESS • Bookmark library — every bookmark from every video on one searchable page • Notes — add a note to any bookmark and find it later • Export — copy or download chapters, bookmarks and notes as Markdown, CSV, JSON or a timestamp list • Chapter loop — repeat one chapter while you practice a song, a language drill or a workout • Skip sponsor chapters — chapters titled with your keywords (sponsor, ad, promo and your own) are skipped, with one-click Undo Everyone who installs during early access keeps Pro for 60 more days after paid plans arrive and gets a founder discount. 🔒 PRIVATE BY DESIGN • No account, no ads, no analytics, no tracking • Settings, bookmarks and notes stay in your browser • Nothing is sent to the developer. The only network requests are video thumbnails from YouTube's own image server • Two permissions (storage and activeTab), and it runs only on youtube.com ▶️ HOW TO USE 1. Open a YouTube video that has chapters or timestamps. 2. The ChapterJump panel appears in the top-right corner of the page. 3. Click a chapter to jump, type to search, or press the bookmark button to save the moment. 💡 TIPS • Had YouTube open while installing? Reload that tab once. • Hide or show the panel with the ChapterJump button on the browser toolbar. • YouTube's Ctrl+← and Ctrl+→ jump to the previous or next chapter, and the panel follows along. ✉️ Found a bug or have an idea?
