Highlight and summarize any page, PDF, or video in Firefox
Glasp is now on Firefox. Highlight web articles, PDFs, and YouTube transcripts in four colors, add notes and tags, and summarize any page or video with ChatGPT, Claude, or Gemini. Everything lands in one searchable library and exports to Notion, Obsidian, or Markdown. Sign in on any browser or on the mobile apps and your highlights follow you. Free, and nothing to migrate.
