Instead of trapping highlights inside one app, Glasp makes them social. Install the extension, highlight a paragraph on any site or a line in a YouTube transcript, and it lands in your Glasp profile where you can add notes and tags. Because highlights are public by default unless you make them private, a feed of what like-minded people are reading and marking emerges — you can follow other users, see what resonates, and discover sources you would not have found on your own. Your library becomes the raw material for AI features. Glasp can summarize a long article, a PDF or a YouTube video so you can decide whether it deserves reading, and it can organize what you have already saved into themes. The standout feature is the AI clone: by training on your own accumulated highlights and notes, it produces something that answers in the shape of your interests and reading history. There is also a digital-legacy angle, letting you hand your accumulated knowledge to someone else. Glasp is free to start, with paid tiers for heavier use and greater AI capacity. Its real niche is learners, researchers, students and content curators who treat annotation as a public, collaborative practice rather than a private bookmark folder — and who want their saved material to do work for them later instead of gathering dust. **Pricing & Plans:** Freemium. A free tier covers the core highlighting, saving and sharing features with limited AI usage; paid plans add higher AI limits and additional capacity. Check glasp.co for current tier pricing, as it is not published in our listing data. - **Web and YouTube highlighting:** Mark up passages on any website or lines in a YouTube transcript from a browser extension, then keep them in one searchable library. - **Social learning feed:** Highlights are shared publicly by default, so you can follow other users, react to their picks and discover sources through people with similar interests. - **AI summarization:** Generate summaries of long articles, PDFs and YouTube videos to judge relevance fast and to digest what you have already saved. - **Your own AI clone:** Trained on your accumulated highlights and notes, the AI clone answers in the shape of your reading history and areas of interest. - **Notes, tags and Kindle import:** Add your own commentary and tags to every highlight, and bring in Kindle highlights so your reading lives in one place. **Strengths:** Turns throwaway highlighting into a genuinely reusable, searchable library; The social feed surfaces sources through people rather than an opaque algorithm; AI summarization and the AI clone are built on your own saved material, not generic content; Works across web pages, YouTube, PDFs and Kindle imports in one place **Limitations:** Public-by-default sharing is not for everyone; private lives behind a toggle you have to remember; The AI clone only becomes useful after you have accumulated a real body of highlights; Free-tier AI usage is limited, so heavy summarization pushes you to a paid plan [Profile (Markdown)](https://openaitools.app/tool/glasp.md) ## JustSummarized JustSummarized targets the everyday problem of content overload. Instead of opening a long article, a dense PDF report or an hour-long video and reading or watching the whole thing, you click the extension's toolbar icon and get a condensed summary in seconds. The extension handles three main content types: ordinary web pages such as articles, blogs and news, PDF documents including academic papers, eBooks and reports, and YouTube videos, which it turns into quick highlights useful for tutorials, lectures and webinars. Beyond straight summarization it adds an interactive Q&A mode. After generating a summary you can ask specific questions about the underlying content and get targeted answers, which is far more efficient than re-reading the source. The extension advertises multi-language output, summarising and translating content across 50+ languages, and states that processing happens locally on your device with no tracking or personal data storage. The listing describes support for Chrome plus Firefox, Edge and Safari, and says it is powered by a mix of models including ChatGPT, Claude, Google Gemini and DeepSeek. The Chrome Web Store version is 1.0.0.3, last updated in January 2025, carries a 4.8 rating from 16 ratings and has a modest install base. It is free to install, and the store listing notes that the extension offers in-app purchases, so some features may sit behind a paid unlock. **Pricing & Plans:** Free to install from the Chrome Web Store. The store listing notes the extension offers in-app purchases, which suggests optional paid upgrades may exist, but the core summarization features are available at no cost. - **One-click web page summaries:** Condense articles, blogs and news pages into a short, readable summary without leaving the tab. - **PDF summarizer:** Extract the key points from academic papers, eBooks and long reports rather than reading them end to end. - **YouTube video summaries:** Turn long videos, lectures and webinars into quick highlights you can scan in seconds. - **AI-powered Q&A:** Ask specific questions about any summarized page, PDF or video and get precise answers drawn from that content. - **50+ language support:** Summarize and translate content across more than 50 languages. **Strengths:** Handles three formats in one extension: web pages, PDFs and YouTube videos; Follow-up Q&A lets you interrogate the content instead of re-reading it; Multi-language summarization and translation across 50+ languages; Free to install with a solid 4.8 user rating **Limitations:** Modest install base, reflecting a smaller, less-proven user community; Chrome Web Store version has not been updated since January 2025; Listing mentions in-app purchases, so not every feature is guaranteed free [Profile (Markdown)](https://openaitools.app/tool/justsummarized.md) ## Frequently Asked Questions ### How do Glasp and JustSummarized compare in monthly traffic?
