Pick Glasp if

Pick NoteGPT if
Your material spans formats and you want AI to do the reading — lecture videos, course PDFs and slide decks all summarized in one place, with flashcards and mind maps. Just budget for the quota behaviour described in our NoteGPT review.
Pick neither if
You mainly summarize YouTube, want it on your phone, and would rather not subscribe. Glasp cannot run on mobile at all; NoteGPT bills monthly with quotas. YT Summarizer is YouTube-focused, web-based so it works on any device, and priced as one-time credits — 5 free, then from $19, never expiring.
