Glasp is a social highlighting and knowledge capture tool built for people who want to save, annotate, and revisit useful ideas from what they read online. It is especially relevant for students, researchers, creators, and knowledge workers who want a lightweight way to build a personal learning trail.
Its main appeal is combining note capture with discovery. Users can highlight articles, webpages, and videos, save those insights, and explore what other people in similar fields are reading. That makes Glasp useful not only for personal note-taking, but also for ongoing curation and idea gathering.
Glasp works best as a reading companion and knowledge capture tool rather than a deep research platform. It is strongest for users who want to remember what they consume and turn everyday reading into a reusable knowledge base.
Features:
- Highlight webpages and PDFs with notes saved to a personal knowledge base
- AI summaries for webpages, PDFs, and YouTube videos
- YouTube highlighting with timestamps and note-taking support
- Chat with your saved highlights and notes to extract insights
- Export highlights to tools like Notion, Obsidian, Roam, and Readwise
Pros:
- Helpful for turning online reading into usable knowledge over time
- Low-friction workflow for capturing research inputs
- Good fit for self-directed learning and research curation
Cons:
- Narrower than full research assistant platforms
- Best for capture and resurfacing, not full end-to-end analysis
- Value depends on a consistent reading and curation habit
