About NoteGPT and MarkerShelf.
notegpt.io links only browser extensions for Chrome and Edge, plus its website (checked Oct 20, 2026). The App Store apps with that name are from other developers. Check the developer name before you pay.
MarkerShelf has a Free plan: up to 10 videos, 3 markers per video, and on every video a transcript preview and a one-sentence summary. The full transcript and summary, translation and search come with Pro ($6.99/mo, or $49.99/yr with a 7-day free trial). NoteGPT also has a free plan, but its pricing page does not list the limits.
Yes. When a YouTube, X or LinkedIn video has no captions, MarkerShelf makes the transcript with speech-to-text. TikTok, Instagram and Facebook videos always go through speech-to-text, and your own videos are transcribed on the device. The summary is written from that transcript.
No. MarkerShelf runs on iPhone and iPad (iOS 26), with iCloud sync between them. There is no web app, Mac app or browser extension. If you work mostly at a computer, NoteGPT fits that better.
Yes, public TikTok, Instagram and Facebook videos up to 180 minutes, even without captions. The full transcript needs Pro.
