## 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

## SummarAI

SummarAI is a focused Chrome extension built around one gesture: select some text on a page, click the extension icon, and read a short summary. There is no dashboard to learn and no separate web app to sign into. It is aimed at students, researchers, professionals and anyone else who wants the gist of a long article, scientific paper or blog post without reading all of it.

The extension gives you control over the output rather than returning a single fixed result. You can ask for a one-sentence summary, a two-to-four-sentence paragraph, or a bulleted list, and you can switch between different AI models depending on the kind of text you are working with. Once a summary appears, you can copy it to the clipboard or regenerate it if the first attempt misses the point.

SummarAI is a bring-your-own-key tool: you must supply an OpenAI API key, which the extension prompts for at installation. There is no bundled quota or paid tier on the developer's side, so your only cost is your OpenAI usage. The listing reports 29 users and a version 1.0 release from May 2023, and the developer declares that no user data is collected. That makes it a small, stable, single-purpose utility rather than an actively expanding product.

**Pricing & Plans:** Free extension with no built-in subscription. You supply your own OpenAI API key and pay OpenAI directly for the requests you make.

- **Summarize highlighted text:** Select any passage on a page, click the SummarAI icon, and receive a concise AI summary without copying the text elsewhere.
- **Three summary formats:** Choose a single sentence, a two-to-four-sentence paragraph, or a bulleted list, depending on how much detail you need.
- **Selectable AI models:** Pick from different AI models so you can match the model to the type of text you are summarizing.
- **Copy and regenerate:** Send a finished summary straight to your clipboard, or regenerate it when the first result is not what you wanted.
- **Bring your own OpenAI key:** Configure your OpenAI API key once during setup and the extension uses it for every summarization request.

**Strengths:** Extremely simple workflow: highlight, click, read; Choose between sentence, paragraph or bullet output; Copy and regenerate controls keep you from redoing work; Runs on your own OpenAI key, so there is no extra subscription

**Limitations:** Requires an OpenAI API key before it can summarize anything; Small user base and no release since its initial 1.0 version; Only English-language support is listed
