## Glasp

Glasp started from a simple observation: most people highlight things they never look at again. 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

## Synopify

Synopify tackles a familiar problem: you land on a long page, a dense corporate site or an unfamiliar domain and you just want to know what it is about before investing time. The extension sits in your browser and, on demand, condenses all the content on the current page into a short, comprehensive overview. Instead of skimming headings and scrolling for minutes, you get the gist in a single view.\n\nWhat sets it apart from a plain summariser is the second half of its job. Synopify also tries to tell you who is behind the website. It uses the current tab's URL and title to extract insights about the page's content and to surface background information on the associated company, then presents a list of key facts alongside a condensed paragraph describing the page. That combination is useful for research, due diligence, sales prospecting and simply deciding whether a source is worth trusting.\n\nThe extension is distributed through the Chrome Web Store under the developer Synopify, based in Wellington, New Zealand. It is lightweight, installs as a normal Chrome add-on and runs in the browser where you are already reading. Its privacy disclosure notes that it handles personally identifiable information, authentication information, web history and website content, and that data is not sold to third parties.

**Pricing & Plans:** Free to install and use. There is no published paid tier; the extension is distributed through the Chrome Web Store at no cost.

- **One-click page summary:** Condenses all content on the current tab into a concise, comprehensive overview you can read in seconds.
- **Company background insights:** Uses the URL and page title to surface who the site belongs to, adding context beyond the article text.
- **Key information list:** Presents a structured list of key facts about the website next to the summary paragraph.
- **Skip manual scrolling:** Understand long articles, landing pages and corporate sites without reading through everything yourself.
- **Runs in Chrome:** A compact extension that works in the browser you are already using, with no separate app to open.

**Strengths:** Combines page summarisation with company background in one view; Removes the need to scroll through long pages to find the point; Free to install from the Chrome Web Store with no signup required; Works on the page you are already reading, so there is no context switching

**Limitations:** Quality depends on how clearly the target page is written and structured; Chrome-only, so it is not available for other browsers; Summaries of very short or media-heavy pages add little value
