## 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

## Horus

Horus is a free Chrome extension designed to act as a reading and research companion while you browse. Its core function is summarization: instead of reading an entire article, you get a condensed set of key points, which is useful for fast readers or anyone who wants the gist before committing time. Because it runs as a browser extension, it integrates directly into your existing browsing flow.

Beyond summaries, Horus answers questions about whatever page you are on. You can highlight a topic and ask for clarification, and the assistant pulls from the page and related web content to respond. This makes it handy for research, study, or casual curiosity without opening a search engine in a new tab. It also covers two common friction points in reading: translation and rewriting, letting you convert page text into another language or rephrase dense paragraphs into simpler wording.

A notable extra is PDF chat. Large documents such as reports and textbooks can be opened and queried directly, so you can extract the information you need without scrolling endlessly. Horus is publisher-distributed through the Chrome Web Store and shows a modest user base, and it is free to install, which makes it easy to evaluate if its approach fits your workflow.

**Pricing & Plans:** Horus is a free browser extension offered at no cost. You install it from the Chrome Web Store and use its summarization, Q&A, translation, rewriting, and PDF chat features without a paid plan.

- **Instant page summaries:** Instantly condense a long web page into a precise summary so you can grasp the main points without reading everything.
- **In-page question answering:** Ask a specific question and get an answer drawn from the current page and related web information without leaving the tab.
- **Text translation:** Translate page text into your preferred language for multilingual browsing and language study.
- **Paragraph rewriting:** Rewrite or paraphrase selected paragraphs into simpler, clearer wording to make complex sentences easier to follow.
- **PDF chat:** Open a PDF inside the extension and chat with it, so large documents, textbooks, and reports become easier to digest.

**Strengths:** Free to install and use, with no subscription barrier; Works inside the browser so you never leave the page you are reading; Combines summaries, Q&A, translation, rewriting, and PDF chat in one tool; PDF chat makes long documents and textbooks easier to digest

**Limitations:** Small user base and low install count may limit community support; Last updated in 2024, so it may not include the newest model capabilities; Listed with no ratings yet, so quality is hard to gauge before installing; Relies on the developer's backend service, so availability depends on the publisher
