About Glasp

Glasp is a note-taking software from Glasp GmbH designed for knowledge management. It provides features such as highlighting, annotation, and sharing so users can efficiently capture and organize information from various sources. Users can save time by easily accessing their collected notes and annotations across devices. Glasp also supports collaboration, allowing users to share insights and resources with peers.

Glasp is a social web highlighter and knowledge management tool designed to help researchers, students, and writers capture and organize insights from the internet. By allowing users to highlight text on web pages and PDFs without leaving the source, Glasp eliminates the friction of traditional copy-paste workflows. Its standout capabilities include AI-powered YouTube video summarization, PDF chat, and the ability to build a 'digital legacy' or AI clone based on a user's accumulated knowledge. The platform emphasizes community-driven learning, enabling users to follow like-minded individuals and discover curated content. Glasp offers robust integration with popular productivity tools like Notion, Obsidian, and Readwise, making it a versatile addition to any personal knowledge management stack. While the core highlighting and social features are free, Glasp Pro provides advanced AI tools, unlimited private highlights, and increased file processing limits. With dedicated mobile apps and seamless cross-device syncing, Glasp serves as a comprehensive hub for capturing, connecting, and reflecting on digital information.
