For iPhone & iPad

Remember everything you watch.

You save hundreds of videos and can never find the part that mattered. MarkerShelf fixes the saved-video graveyard — bookmark the exact second, not the whole video.

The problem

Your saved videos are a graveyard.

Likes, shares and bookmarks save the whole video — never the moment. So the recipe step, the drill, the one quote you needed gets buried, and you scrub for minutes to find it again.

Scattered everywhere

Saves live in each app — YouTube here, Instagram there. Nothing is in one place you can actually search.

Whole video, not the moment

A bookmark points at the page. You still scrub through 40 minutes to reach the 12 seconds that mattered.

Impossible to find later

No notes, no tags, no transcript. Future-you has no idea why past-you saved it.

Core idea

Bookmark the moment, not the video.

Watching anything? One tap captures the exact second — with a screenshot of that frame, your note, and tags. Tap the marker later and the video jumps straight back to it.

  • Auto-screenshot of the exact frame
  • Notes, #tags and location on every marker
  • Tap to jump the player back to that instant

Practice & review

Mark a span. Loop it forever.

Range markers capture a whole segment, not just a point. Flip on loop and MarkerShelf replays it on repeat — perfect for drilling a move, a guitar riff, or a tricky recipe step until it sticks.

  • Two-handle start/end selection
  • A–B loop that never stops
  • Works on every source, even web video

Find anything

Search what was said, written, or tagged.

Every moment becomes findable. Search runs across video titles, your notes, your tags — and even the transcript of what was spoken.

Full-text search

Find a moment by what was said on screen, the note you wrote, or the title — instantly.

Tags & tag cloud

Type #recipe and filter every matching moment. No manual folders, ever.

Transcripts

Read along, tap a line to seek, and let marker notes pre-fill from the dialogue.

Collections

Themed playlists across every platform.

Group videos and individual moments into collections, then hit play. MarkerShelf runs them back-to-back — YouTube into TikTok into your own clip — as one continuous, auto-advancing playlist.

  • Mix sources in a single playlist
  • Auto-advance with smooth crossfade
  • Export a collection to Text, Markdown or PDF

FAQ

Good questions.

Which platforms can I save from?

YouTube, Instagram, TikTok and Facebook via a link or the iOS share sheet, plus your own videos from Photos and Files. Everything plays inside MarkerShelf, so markers and loops work the same across all of them.

How is this different from bookmarking or liking a video?

A like or bookmark saves the whole video. MarkerShelf saves the exact second — with a screenshot, a note and tags — so you jump straight to the moment instead of scrubbing to find it.

What do range markers and looping do?

A range marker captures a start-to-end segment. Turn on loop and that span replays continuously — ideal for practicing a move, a riff or a recipe step. Range & loop markers are part of Pro.

Do I need an account?

No. You can start marking moments for free with no sign-up. The free tier includes up to 10 videos, 3 markers each, 5 tags and full search.
