MarkerShelf
MarkerShelf does one thing: it keeps the videos you save from six platforms, and the moments inside them.
Glasp
Glasp covers far more than video, on far more devices. If those matter to you, it is the better pick.
Glasp and MarkerShelf overlap only on YouTube summaries. Many people would use Glasp for reading on the computer and MarkerShelf for the videos they save on the phone, including TikTok and Instagram, where Glasp's pages mention only YouTube for video.

About Glasp and MarkerShelf.
Glasp has a free plan with basic YouTube summaries 3 times a day, advanced summaries 3 times per 7 days and 30 minutes of audio transcription a month. Pro is $12.50/mo billed yearly or $15/mo, and Unlimited is $30/mo (glasp.co/pricing, Oct 20, 2026, US).
Glasp's pages mention only YouTube for video (checked Oct 20, 2026). MarkerShelf works with TikTok, Instagram, Facebook, X and LinkedIn videos as well as YouTube, and transcribes their speech even when there are no captions.
Yes, they do different jobs. Glasp keeps highlights from what you read and watch in a browser; MarkerShelf keeps videos and the moments in them on iPhone and iPad. MarkerShelf exports markers as Markdown with Pro, so your video notes can sit next to your Glasp highlights in the same notes app.
No. MarkerShelf is for videos only: YouTube, TikTok, Instagram, Facebook, X, LinkedIn and your own. For articles and PDFs, Glasp or a read-later app is the better tool.
Not yet. MarkerShelf is on iPhone and iPad today, and an Android app is in development. Glasp has an Android app (50K+ downloads on Google Play), so for now it is the better choice if you switch between Android and iPhone.
Save videos from six platforms, keep the moments that matter, and get transcripts and summaries on iPhone and iPad.
