Glasp is part of a growing category of “social highlighters” that allow you to capture insights from the web and share them publicly. If you like the community-driven aspect of Glasp, several other platforms offer similar social highlighting or public knowledge-sharing features.
Primary Social Highlighting Alternatives
- Hypothesis: A mature, open-source platform that enables a conversational layer over any webpage, article, or PDF. It allows for public, private, or group-specific annotations, making it a strong choice for collaborative learning and scholarly discourse.
- Diigo: A veteran in the space that blends social bookmarking with robust annotation tools. You can highlight text, add virtual sticky notes, and save annotated pages to a public or private cloud library. It is especially effective for organizing large digital research libraries with tags and outliners.
- Instapaper: While primarily a read-it-later app, Instapaper profiles and folders can be made public. This allows you to share your curated highlights and notes with a wider audience to enhance your online visibility.
- Liner Copilot: An AI-powered research platform that allows you to highlight text and ask an AI copilot to explain or elaborate on the content. It includes collaboration features for sharing AI-enhanced summaries with team members. [1, 2, 3, 4]
Public Knowledge-Sharing & Curation Tools
- Medium: A platform designed for “growing in public” where you can highlight and share key phrases from articles. Most highlighted sections are often displayed more prominently, and the platform notifies you when others highlight the same text.
- Raindrop.io: A bookmark manager that allows you to organize, share, and collaborate on collections of digital content. It features a web highlighter that keeps highlights visible on the original page when you revisit it.
- Notion: While it is a general workspace, its public template feature is highly popular for sharing reading lists and book quote databases. It can be connected with highlighting extensions to sync your notes and make them actionable.
- UpWord: Designed for researchers and distributed teams, it turns any webpage or YouTube video into shareable AI notes and stores them in a searchable library. [3, 4, 5, 6, 7]
Social Platforms with Highlighting Features
- Reddit: Glasp maintains an official community (r/Glasp) where learners and creators share highlights and discuss research.
- LinkedIn: Professionals often use LinkedIn to share highlights, summaries, and reading lists to start conversations with their network. [4]
