Glasp

Glasp is a social web highlighter that collects your reading highlights and turns them into AI summaries and notes.

Overview

Glasp lets you highlight web pages, PDFs, and YouTube videos, then organizes those highlights into a knowledge library you can search, tag, and share. Its AI features generate summaries from your highlights, answer questions about saved content, and produce study notes. Because highlighting is social, you can follow other readers’ annotations on the same pages — a community-powered way to read the web.

The social layer creates genuine discovery: follow thoughtful readers and their highlights appear in your feed, turning solitary reading into a shared activity. Export to note-taking tools keeps your highlights portable, avoiding lock-in.

• Highlighting for web pages, PDFs, and YouTube
