## 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

## ReadSmart

ReadSmart is a small Chrome extension whose single job is to make long web pages easier to get through. Once installed, it adds a button to the browser sidebar; click it on any page you are reading and ReadSmart sends the page text to a language model, then returns a condensed summary in place. The developer pitches it specifically at content-rich pages — news articles, blog posts, documentation — where the value is buried in a lot of prose.

The feature set is deliberately narrow. There is one-click summarization, page detection geared toward heavy text, and a history of summaries you have already generated so you can revisit something you skimmed earlier. The listing also notes that the extension works on top of your normal browsing rather than replacing it, which keeps the learning curve minimal.

ReadSmart is free to install, with the store listing indicating in-app purchases. It was last updated in November 2023 and has a small user base, so treat it as a simple utility rather than a full reading or research platform: there is no source collection, no writing assistance and no workspace. If you just want a quick AI summary of whatever page is open in front of you, that simplicity is the point.

**Pricing & Plans:** ReadSmart is free to install from the Chrome Web Store. The listing states that the extension offers in-app purchases, so optional paid features may exist.

- **One-click page summaries:** Press the sidebar button on any page and ReadSmart returns a condensed summary of the page's text without you scrolling through everything.
- **Built for text-heavy pages:** Rather than dumping the whole page into a summary box, the extension detects the main textual content, which works best on news sites and long-form blogs.
- **Summary history:** Summaries you have already generated are kept, so you can return to a page you read earlier and jump straight back into the gist.
- **Sidebar workflow:** The extension lives in the Chrome sidebar, so generating a summary never pulls you out of your current tab or workflow.

**Strengths:** Free and quick to install from the Chrome Web Store; One-click summaries keep you inside your current tab; Summary history lets you revisit pages you skimmed earlier; Very low learning curve — one button, one output

**Limitations:** Narrow scope: summarization only, with no writing or research features; Small user base and last update in late 2023; Handles personal data and website content, so review the privacy policy before use
