MarkerShelf

What they say it does

Bookmark the exact second in any video — with a screenshot, a note, and your own tags. Share from YouTube, TikTok, Instagram, or your camera roll; MarkerShelf saves the moment, not the whole video. Mark a span and loop it until you nail the rep or the chord. No captions? Generate a transcript and summary, then search by spoken word and jump straight to that second. Group markers into collections, export as text or images. iPhone and iPad, works offline for local video.
