Glasp is a social PDF and web highlighter that enables users—especially researchers, students, and lifelong learners—to highlight, bookmark, and annotate content from web pages, PDFs, YouTube videos, Kindle, and more. It allows users to collect, organize, and share their highlights and notes, build a personalized AI clone based on their reading activities, and export or sync their notes to various productivity and note-taking platforms. Glasp's collaboration and discovery features create a collective knowledge-sharing community.
