## 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

## ireadfaster

ireadfaster is a small, single-purpose Chrome extension built to answer one question fast: what is this video actually about? Once installed, it adds two panels to the YouTube watch page — "Summary" and "Transcript". Pressing Generate in either panel sends the video's content off to an OpenAI-backed API and returns a condensed overview or the spoken text within seconds. The extension's defining detail is that the output is clickable: tapping any line in the summary or transcript jumps the YouTube player to the corresponding point in the video, which turns a summary into a navigation tool rather than just a wall of text.

The extension is published by the developer not.pizza, based in Chicago, and is listed on the Chrome Web Store at version 0.0.17 with a small but well-rated user base. It is offered free of charge. Because every generation costs the developer a few cents in API usage, the extension may ask you to sign in with a Google account before generating — a light anti-abuse measure rather than a paid tier. The developer's privacy disclosure states that data is not sold to third parties and is not used for unrelated purposes.

As a lightweight utility it is best suited to people who watch a lot of long-form video — lectures, interviews, conference talks, reviews — and want to triage content quickly or search inside a video without scrubbing. It is a browser extension, not a platform: there is no dashboard, no library of past summaries, and no mobile app. Install it from the Chrome Web Store and it appears on the YouTube UI; remove it and nothing is left behind.

**Pricing & Plans:** Free. The extension is published on the Chrome Web Store at no cost, and no paid tier is advertised on its listing. Each generation incurs a small API cost for the developer, which is why a Google sign-in may be requested to prevent abuse.

- **In-page summary panel:** Adds a Summary section beside any YouTube video so you can read the gist before committing to watching.
- **Full transcript on the YouTube UI:** Generates the spoken text of the video without leaving the watch page or opening a third-party site.
- **Click-to-seek output:** Click any line of the summary or transcript to jump the player to that exact moment in the video.
- **OpenAI-powered generation:** Summaries and transcripts are produced through an OpenAI-backed API rather than a fixed template.
- **Google sign-in anti-abuse gate:** A lightweight sign-in may be required before generating, to stop automated misuse of the paid API.

**Strengths:** Free to install and use, with no subscription mentioned on the listing; Summary and transcript appear inline on YouTube, so no tab switching; Click any line to seek to that moment in the video; Small, focused tool — rated 5.0 by early users and used by a modest active base

**Limitations:** Chrome only — no Firefox, Safari or Edge-specific build advertised; Last updated August 2024, so newer YouTube UI changes may affect the panels; Requires a Google sign-in before generating, which some users will not want to do; No archive or history of previously generated summaries
