Glasp

Highlight the web, learn in public, and build your AI clone

Web and YouTube highlighting

Mark up passages on any website or lines in a YouTube transcript from a browser extension, then keep them in one searchable library.

Social learning feed

Highlights are shared publicly by default, so you can follow other users, react to their picks and discover sources through people with similar interests.

AI summarization

Generate summaries of long articles, PDFs and YouTube videos to judge relevance fast and to digest what you have already saved.

Your own AI clone

Trained on your accumulated highlights and notes, the AI clone answers in the shape of your reading history and areas of interest.

+The social feed surfaces sources through people rather than an opaque algorithm
+AI summarization and the AI clone are built on your own saved material, not generic content
+Works across web pages, YouTube, PDFs and Kindle imports in one place
