## 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

## SummarizeIt

SummarizeIt is a lightweight Chrome extension for people who want the gist of a page without reading all of it. Published by the developer archlab, it works on the page open in your browser tab and uses OpenAI's GPT-3 API to generate a condensed version of the main text. The pitch is straightforward: instead of skimming paragraph after paragraph for the important sentence, you trigger the extension and read a short summary instead.

The extension is deliberately simple. There is no elaborate dashboard, no team workspace and no workflow builder — just a summarization action delivered inside the browser where you are already reading. Because it operates on the active page, it fits naturally into research, study and news-reading habits where you jump between many sources in a single session and need to decide quickly which ones deserve a full read.

SummarizeIt is listed in the Chrome Web Store with a small user base of around two hundred installs and version 2.0 as its most recent release. It is offered free of charge. Note that the extension dates from 2023 and is built on GPT-3, so newer summarizing tools based on GPT-4-class models may produce tighter output; SummarizeIt remains a simple, no-cost option for a quick page digest provided the developer's API integration keeps functioning.

**Pricing & Plans:** Free. The extension is distributed at no cost through the Chrome Web Store and advertises no subscription or paid tier.

- **One-click webpage summary:** Summarize the page in your active Chrome tab without copying or pasting any text.
- **GPT-3 powered output:** The extension uses OpenAI's GPT-3 API to generate condensed, readable versions of long text.
- **Lightweight extension workflow:** Install from the Chrome Web Store and use it while browsing; no configuration screens or account setup are described.
- **Reading-time saver:** Built for getting the gist of long articles, posts and pages without reading every paragraph.

**Strengths:** Free to install and use, with no subscription tier advertised; Runs inside Chrome on the page you are already reading, so there is no context switching; Cuts long articles down to a short digest so you can decide what deserves a full read; Minimal interface keeps the focus on the summary itself
