Mark moments in YouTube videos, label them, and jump back instantly. Watching a two-hour tutorial and need to find "the part where they install the dependencies" again? Mark it. Press B while watching any YouTube video to mark the exact moment, then give it a label. Your marks appear as ticks on the video's progress bar — hover to see the label, click to jump straight there. WHAT YOU GET • Mark with the B key or the bookmark button in the player controls • Label every mark, and rename or delete it any time • A marks panel next to the video — one click to jump • A dashboard of every video you've marked, searchable by title, channel, or label • Copy your marks as a chapter list or as timestamped links, ready to paste into your notes PRIVATE BY DESIGN Everything is stored in your own browser.
