What is Glasp?
Glasp is a free AI-powered highlighting and knowledge curation tool designed for researchers, students, and lifelong learners who consume large volumes of web content and need an efficient way to capture, organize, and revisit key insights. Available as a browser extension for Chrome and Safari, Glasp lets you highlight text on any web page or PDF, add notes and tags, and automatically saves everything to your personal knowledge base where it becomes searchable and shareable.
What sets Glasp apart from traditional bookmarking or note-taking tools is its social and AI layers. Every highlight you make contributes to a shared knowledge graph — you can discover what other learners have highlighted from the same articles, follow thought leaders in your field, and build upon collective insights. Glasp’s AI features automatically generate summaries of your highlights, create flashcards for spaced repetition learning, and can produce AI-powered newsletters from your curated content. The tool also integrates seamlessly with popular note-taking apps like Notion, Obsidian, and Roam Research, ensuring your highlights flow into your existing knowledge management workflow.
