What is Glasp?
Glasp is a web highlighter tool that lets users mark, annotate, and save passages from any webpage directly in the browser, then organize those highlights into a personal knowledge library that can be shared socially with other readers. The tool operates as a browser extension and surfaces a social layer on top of standard reading — showing what other Glasp users have highlighted on the same page, which adds collaborative discovery to individual research sessions. Researchers and professionals who read heavily online face a consistent problem: valuable insights are scattered across dozens of tabs, browser bookmarks produce no usable context on return visits, and note-taking apps require context-switching away from the source material. Glasp solves this by embedding the annotation layer directly into the reading experience — highlights are captured in context, tagged, and stored without leaving the page. The personal knowledge library accumulates over time into a searchable archive of everything a user has found meaningful across months or years of reading. Glasp is not suitable for teams needing collaborative document editing, real-time co-annotation on private files, or enterprise knowledge management with admin controls and permission tiers — tools like Notion AI or Readwise Reader serve those workflows more completely. Glasp's value is strongest for individual learners and researchers who consume high volumes of public web content and want a social discovery layer alongside their personal archive.
Glasp is a web highlighter tool that lets you annotate, save, and socially share web content highlights — building a personal knowledge library across any browser.
Glasp is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.
