Glasp: Social Web Highlighter & AI Note-Taking Tool

Glasp reimagines the humble highlighter for the digital age, transforming it into a social learning and knowledge management powerhouse. Instead of switching between tabs and apps to save quotes and ideas, users can highlight directly on webpages and PDFs, tag and organize their findings, and instantly sync everything to favorite note-taking apps like Notion, Roam Research, and Obsidian. It's less about passive bookmarking and more about active, structured learning that sticks. What sets Glasp apart is its social and AI-driven layer. Every highlight can be public by default, creating a searchable web of insights from like-minded learners, researchers, and writers around the world. On top of that, Glasp lets users train a personalized AI clone using their own accumulated highlights and notes—essentially building a digital brain that reflects their unique knowledge and reading history. Add in AI-powered summarization for YouTube videos, PDFs, and webpages, plus Kindle highlight imports, and Glasp becomes a genuine second brain for anyone who reads, researches, or creates content for a living.

Install the Glasp extension for Chrome or Safari, then start highlighting text directly on any webpage or PDF you're reading. Add personal notes to your highlights, and organize everything using tags and author labels for easy retrieval later. Import your existing Kindle highlights to consolidate all your reading history in one place, and use the built-in AI tools to generate quick summaries of YouTube videos, long articles, or PDFs. Once your highlights are organized, sync or export them to apps like Notion, Roam Research, or Obsidian, and share your public highlights with the Glasp community or embed them on your own blog.
