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. Spotted a flaw in your deadlift at 0:21? Mark it, write “hips rising too early”, and tap the marker later to jump the video straight back to that instant.

  • 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. Set the start and end handles around the guitar riff, flip on loop, and MarkerShelf replays it on repeat — perfect for drilling a move, a lick, 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

Zero friction

Save from the app you’re already in.

No copy-pasting links. In Safari, YouTube, Instagram — anywhere — tap Share, pick MarkerShelf, and the video lands in your library ready to mark. Paste a link works too, if that’s your style.

  • One tap from the iOS share sheet
  • Title, thumbnail and duration fetched automatically
  • Your own videos import from Photos & Files

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 on screen.

Search

Type a word. Land on the second it was said.

Search “equilibrium” and MarkerShelf surfaces the lecture, the marker, and the exact transcript line — tap a result and the video seeks right there. Titles, notes, tags and speech, all in one search box.

Transcripts

Every word, written down — on your device.

Generate a transcript of any video with one tap, entirely on-device. Read along while it plays, tap a line to seek to it, and get an AI summary of the whole video without anything leaving your phone.

  • On-device transcription — private by design
  • Tap any line to jump the video there
  • AI summary with the key points

Live captions

Watch with subtitles — even where there are none.

Once a video has a transcript, MarkerShelf overlays live captions right on the player. Follow a fast lecture, watch without sound on the train, or catch the words a mumbling instructor swallows.

Tags

#tags instead of folders.

Tag videos and individual markers as you go — #form, #chem101, #recipe. The tag cloud shows your whole library at a glance, and one tap filters every matching moment. No manual folders, ever.

Collections

Themed playlists across every platform.

Group videos and individual moments into collections like “Technique drills”, 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
  • Play just the marked moments, or full videos

Take it with you

Your notes, out of the app.

Export a video or a whole collection — markers, notes, tags and screenshots — as a clean PDF, Markdown for your notes app, or plain text. Study sheets, training recaps and recipe cards build themselves.

  • PDF with screenshots and timestamps
  • Markdown that drops into Notion or Obsidian
  • Plain text for anywhere else

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.

Are transcripts and captions private?

Yes. Transcription, AI summaries and live captions are generated entirely on your device. Your videos, notes and transcripts never touch our servers — sync happens through your own iCloud.

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.
