## 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

## Summatim

Summatim is a Chrome extension whose whole purpose is to stop you from spending hours on a YouTube video that may not contain what you are looking for. Once installed, it can analyze the content of a video and return a concise summary of its key points, so you can quickly gauge whether the material matches your interests before deciding to watch the whole thing.

The extension is deliberately small and focused. It is not a general-purpose page reader or a note-taking suite; it exists to add a summarization action on top of YouTube. That makes it a natural fit for people who use video as a primary source of information — students working through recorded lectures, professionals following long interviews or conference talks, and anyone who wants to preview a review or tutorial rather than sit through all of it.

Summatim presents itself on the Chrome Web Store as a follow-up to its original YouTube summarization concept, with the extension listed as "Featured" and rated 5.0 by its (currently modest) set of reviewers. Because the value of a summarizer depends heavily on how faithfully the summary represents the source, it is best used as a fast orientation tool: get the gist first, then watch the segments that actually matter to you.

**Pricing & Plans:** Freemium. The Chrome Web Store listing categorizes Summatim as freemium, with the core extension available to install and paid options offered through the listing.

- **YouTube video summaries:** Run the extension on any YouTube video and receive a short digest of its key points.
- **Save viewing time:** Check whether a long video contains what you need before committing to watching it all.
- **Lightweight browser extension:** Installs as a small, unobtrusive Chrome extension that adds a summarize action to YouTube.
- **Works on long-form content:** Useful for lectures, interviews, reviews and long-form talks where the important parts are buried in the middle.

**Strengths:** Purpose-built for YouTube videos; Very small extension footprint; Helps you decide fast whether a video is worth watching; Highly rated by its current reviewers

**Limitations:** Small installed base compared with mainstream summarizers; Latest listing update dates to April 2024, so newer YouTube layout changes may affect reliability
