## 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

## VidSense

VidSense is a small, single-purpose browser extension distributed through the Chrome Web Store. Once installed, it works only on the YouTube video in your active tab: click the extension icon and it reads the video's captions to produce answers, summaries, quizzes, translations or custom prompts. There is no separate dashboard, no account wall described on its listing, and no data-collection disclosure beyond the developer's statement that data is not sold to third parties.

The design goal is to remove friction from video study. Instead of jumping to a third-party summarizer site, pasting a link and copying results back, VidSense keeps the interaction inside YouTube. That makes it useful for lecture review, tutorial skimming and quick fact-checking of a talk you are half-way through.

VidSense is an indie project with a modest audience, so treat it as a convenience utility rather than a full-featured research platform. It is best for students and self-directed learners who watch a lot of educational video and want answers without a transcript detour.

**Pricing & Plans:** Listed as free on the Chrome Web Store. The listing shows no paid tiers or in-app purchase information, and there is no published pricing page to verify a premium plan — assume a free, ad-free utility with no paid upgrade documented.

- **Ask questions about the current video:** Type a natural-language question and get an AI answer grounded in the YouTube video that is open in your active tab.
- **One-click video summaries:** Generate a condensed summary of a long video to grasp the main points before deciding whether to watch it in full.
- **Quiz and prompt generation:** Create practice quizzes, request translations, or write custom prompts so the video's content becomes interactive study material.
- **Works inside the YouTube tab:** No external site, no link pasting and no separate dashboard — the assistant runs as an overlay on the page you are already on.
- **Minimal data footprint:** The developer declares that user data is not sold to third parties and is used only for the extension's core functionality.

**Strengths:** Zero setup friction: install and it works on the video already open; Focuses on question answering rather than only static summaries; Keeps you inside YouTube instead of bouncing to another summarizer site; No documented account requirement or paid tier

**Limitations:** Very small user base and only a handful of ratings, so reliability signals are thin; Last extension update was mid-2024, suggesting a slow maintenance cadence; Depends on YouTube captions, so videos without usable subtitles limit accuracy
