Glasp

Glasp is a social web and PDF highlighter designed to help users capture, organize, and reuse knowledge from online content. It enables you to highlight text, add notes, and save key ideas from articles, PDFs, and web pages directly in your browser. The platform’s core purpose is to turn scattered reading into a structured, searchable knowledge base that can be shared and leveraged through AI-driven features.

Key features include browser-based highlighting and annotation, automatic saving of source links, and organized views of your highlights by topic, tag, or source. Glasp also offers a social layer, allowing you to discover, follow, and learn from other users’ public highlights and notes, effectively crowdsourcing insights on specific subjects. A notable capability is the creation of a personalized AI “clone” trained on your saved highlights and annotations, which can answer questions and generate summaries aligned with your reading history. Integrations with popular tools and export options help you move your notes into other workflows or knowledge systems.
