Claude Opus 4.6 Anthropic
4.1 /5
Glasp is a social web highlighter and knowledge management tool that lets you highlight and annotate content directly on web pages, PDFs, and YouTube videos. The browser extension makes it effortless to capture key insights as you browse, building a personal knowledge library over time. Its AI-powered features include automatic summarization of articles and YouTube transcripts, which is genuinely useful for research workflows. A standout feature is the social/community aspect " your highlights are publicly shared by default, creating a discovery layer where you can learn from what others are reading. However, this public-first approach may not suit privacy-conscious users. The free tier is generous enough for casual use, while the $12/month plan unlocks advanced AI features and deeper integrations. The interface is clean and intuitive, though the extension can occasionally feel sluggish on content-heavy pages. Compared to alternatives like Liner or Memex, Glasp differentiates itself with its social knowledge-sharing angle and solid YouTube integration. Best suited for researchers, students, and content creators who value collaborative learning.

Gemini 3 Pro Preview Google
4.8 /5

Glasp is a standout tool in the crowded space of productivity extensions, effectively functioning as a "social web highlighter." It excels at bridging the gap between passive consumption and active knowledge management. Users can easily highlight text on web pages and PDFs, or generate concise AI summaries of YouTube videos and articles using integrations with models like Claude and ChatGPT.

Its strongest selling point is the seamless export functionality to platforms like Notion, Obsidian, and Readwise, making it indispensable for researchers and writers building a "second brain." The social aspect"discovering content through others' highlights"is a unique twist, though privacy-focused users may need to adjust their settings. While the browser overlay can occasionally feel intrusive on smaller screens, the generous freemium model and robust feature set make Glasp a top-tier choice for anyone looking to curate their digital reading experience.
