What is Glasp?
Glasp is a highlighting and knowledge-management tool for researchers, students, writers, and lifelong learners. It captures text and notes from webpages, PDFs, YouTube videos, and Kindle books, then stores the material in a searchable personal library. Users can organize highlights by tag or author, share them with others, and use AI to summarize saved sources or answer questions based on their collected material.
Glasp works through extensions for major browsers and mobile apps for iOS and Android. Its mobile reader supports articles and PDFs, while the iOS extension can highlight content in Safari. The service also provides import and export options for moving reading data between Glasp and other note-taking or reading tools.
