Glasp

Reading on the web often leaves good ideas scattered across tabs and bookmarks. Glasp gathers highlights and notes from articles, PDFs and videos in one place, then adds AI summaries so you can review material quickly. Its social side, where you can follow other readers and browse their highlights, gives it a community feel that most note tools lack.

• Colored highlights on websites and PDFs are saved automatically to your personal Glasp page.
• AI summaries for YouTube videos, articles and PDFs can use ChatGPT, Claude, Gemini or Mistral, with prompts you can customize.
• Tags, search and links make it easier to resurface old reading.
• Highlights can be shared to platforms such as X, Slack and Teams.
• Paid plans add PDF uploads, audio transcription, private highlights and Notion sync, and the company offers a student discount.

Glasp is best for students, writers, researchers and lifelong learners who read a lot online and want a lightweight way to keep what matters. A practical tip: customize the summary prompt early, for example asking for key takeaways plus quotes, so your saved summaries follow a consistent format that is easier to review later.
