## 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

## Summarizing Tool

Summarizing Tool is a browser extension published by summarizingtool.io and distributed through the Chrome Web Store. Its purpose is narrow and practical: paste or load a long piece of text, and the extension compresses it into a shorter version that captures the important points so you do not have to read the full document.

The extension leans on AI to decide which passages carry the substance and which are filler, then produces an overview that reads naturally rather than as a mechanical excerpt. Because it runs inside the browser, you stay in the same tab where you were reading instead of moving text into another app.

It is positioned as free for everyone, with no monthly subscription required, and the developer declares that no user data is collected or sold to third parties. The listing shows a modest but positive user base, with a 4.3 average rating and a clean publisher record on the Chrome Web Store.

**Pricing & Plans:** Free. The developer states no monthly subscription is required and the tool is free for all users.

- **AI-based text reduction:** Identifies which passages of a long document matter and rewrites the rest away, producing an overview rather than a raw first-paragraph excerpt.
- **Fast results:** Generates summaries in a fraction of the time manual note-taking would take, so you can skim a long article or report in seconds.
- **Works on long-form content:** Built for articles, reports, essays, and study material where the input is long enough that reading everything is impractical.
- **Free with no subscription:** No payment, trial, or monthly plan is required to use the extension.
- **Runs inside Chrome:** Installs as a lightweight Chrome add-on (under 1 MB) so summarization happens in the same browser you already read in.

**Strengths:** Completely free with no subscription or account required; Installs as a small, lightweight Chrome extension; Developer has a clean record and declares no data collection; Useful for anyone who regularly faces long text and limited time

**Limitations:** Only works inside Google Chrome; Listing has a small user base and relatively few ratings; Performs one task only, with no advanced workspace or export features
