## 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

## HackSEO

HackSEO is a browser extension with a deliberately blunt promise: it sifts through internet nonsense and translates it into something you can actually understand. Web pages are increasingly written for search engines, procurement departments or legal review rather than for readers, and the result is text that is long, padded and full of jargon. HackSEO applies AI to that text and hands back a clearer version.

The extension fits into normal browsing rather than replacing it. Instead of copying paragraphs into a separate chatbot, you invoke it on the page you are already reading and let it simplify, shorten or restate the content. That makes it practical for dense product documentation, marketing pages full of buzzwords, policy documents, news analysis and technical write-ups where the underlying facts are simple but the wording is not.

The listing is a small, single-developer extension — version 1.0.0 from April 2024 with a modest user base and no ratings so far — which is worth knowing before you depend on it. Its store page also discloses collection of personal, financial, communications, browsing and usage data, so reading the developer's privacy policy is a sensible first step if you plan to use it on sensitive pages.

**Pricing & Plans:** Listed as a freemium browser extension. The Chrome Web Store listing shows no price, so check the store page or developer for current costs.

- **Plain-language rewriting:** Rewrites dense articles, reports and product pages into shorter, plainer phrasing that is easier to grasp quickly.
- **Summarisation of long content:** Condenses long passages so you can judge whether the substance is worth reading in full before committing.
- **Jargon removal:** Turns corporate, legal and technical vocabulary into everyday words without needing a dictionary detour.
- **In-browser workflow:** Runs in the browser as a Chrome extension, so it works alongside your normal browsing rather than in a separate app.

**Strengths:** Straightforward, single-purpose tool with no learning curve; Runs inside Chrome, so simplified text stays in your reading context; Useful for jargon-heavy corporate, legal and technical pages; Lightweight extension at roughly 351KiB

**Limitations:** Very small user base and no ratings, so reliability signals are thin; Last updated April 2024, so the underlying AI may lag newer models; Listing discloses broad data handling, which warrants privacy review
