MarkerShelf

MarkerShelf bookmarks the exact second in any video, with a screenshot, a note and tags. Works with YouTube, TikTok, Instagram, Facebook, X, LinkedIn, and local videos from Photos or Files. Share from the app you are already in and the moment lands in one searchable library. Mark a span and loop it until the rep, the chord or the 8-count sticks. No captions? Generate a transcript and an AI summary, then search any spoken word and jump straight to that second. Group moments into collections, play them back marker to marker, and export as PDF, Markdown or plain text. Built for people who learn from video: students, home cooks, lifters, musicians, dancers. iPhone and iPad, synced through your own iCloud, no account needed. Free to start. Pro unlocks range loops, collections, transcripts and AI notes.
