About Glasp
Glasp is a social web highlighter that lets you highlight and annotate text on web pages and PDFs directly in the browser.
It generates AI summaries of highlighted content and builds a personal knowledge graph of your saves that you can share via a public profile. Highlights export to note-taking tools including Notion, Obsidian, and Readwise.
It suits researchers and readers who want to capture and share what they read, and it is beginner-friendly. Note the limits: the free tier caps monthly highlights, advanced AI summaries and unlimited exports need a paid subscription, and the extension targets Chromium-based browsers with no official Firefox version.
Against other read-and-annotate tools, its distinguishing angle is the social, shareable knowledge graph layered on top of standard highlighting and export.
