Glasp - The Social Web Highlighter and Collective Wisdom Engine

Glasp (Greatest Legacy Any Shared People) is a unique “Social Web Highlighter” that allows users to capture, organize, and share highlights and notes from the internet. Unlike traditional bookmarking tools that keep your insights in a private silo, Glasp focuses on Public Learning, allowing you to see what other like-minded thinkers are finding valuable. In 2026, it is recognized as a vital tool for the “Knowledge Graph” movement, connecting human curiosity with AI-powered discovery.
