Glasp

You read something great online, think "I'll remember this," and forget it by tomorrow. Glasp is a free Chrome extension that fixes that habit. Highlight anything on websites or PDFs with color-coded options, and your highlights are automatically saved and organized in your personal Glasp homepage — tagged, searchable, and ready to link or share on Twitter, Teams, Slack, and more.

But Glasp goes beyond just saving your own reading. You can explore what other like-minded learners are highlighting, discover insights you might have missed, and even build an AI clone from your own highlights and notes. YouTube videos, web articles, and PDFs can all be summarized using AI models including ChatGPT, Claude, and Mistral AI. It's the reading companion that turns passive browsing into active, lasting knowledge.
