🔍 What is Glasp?

Glasp (Great Layout and Summarization Platform) is a unique AI-powered social web highlighter and note-taking tool that allows users to highlight text, take notes, and organize knowledge from any web page. Unlike traditional bookmarking tools, Glasp captures the actual content you find valuable — highlighted passages, notes, and tags — and organizes them into a personal knowledge library that can be searched, shared, and revisited. The platform adds a social dimension by allowing users to follow others' highlights and discover curated content from like-minded individuals.\n\nGlasp's AI capabilities enhance the highlighting experience with automatic summarization, topic extraction, and content categorization. When a user highlights content, Glasp's AI can suggest related topics, generate summaries of the highlighted passages, and automatically tag content for organization. The platform also features a Y Combinator (YC) startup highlights section and supports highlighting on YouTube videos, PDFs, and Kindle books, making it a comprehensive knowledge capture tool across multiple media types.\n\nWhat sets Glasp apart is its community aspect — highlighted content is shared publicly by default (with private options available), creating a network effect where users can discover valuable content through the highlights of people they follow. For researchers, lifelong learners, and content curators, Glasp provides a way to build a searchable, shareable knowledge base from everything they read online. The platform is available as a Chrome extension and offers export options including Markdown, CSV, and integration with note-taking apps like Notion and Obsidian.
