## 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

## Noiz

Noiz is built around a simple promise: skip the watching and still get the knowledge. Instead of copying a link into a separate tool and crafting a prompt, you install a browser extension, open a YouTube video, and click summarize. Noiz returns the key ideas as a clear list, optionally with timestamps that jump to the exact moment, plus a full video-to-text transcript when you need the words, not just the gist. It handles everything from a two-minute clip to a multi-hour course or podcast.

The product also ships mobile apps for iOS and Android, so the same summaries are available when you are away from your desk. Beneath the summarizer sits a wider library of free AI utilities covering transcripts, PDF and article summaries, text summarizers, content generators, and YouTube growth helpers like title, description, and tag generators. Summaries can be translated into more than 40 languages, and a weekly top-100 view helps you track what is trending on YouTube.

Noiz positions itself as a learning and productivity companion rather than a media downloader. The audience is students, researchers, and professionals who consume a lot of long-form video and want structured notes instead of raw playback time. It reports more than half a million users, with a free trial that leads into a paid subscription.

**Pricing & Plans:** Free trial, then paid subscription. You can test Noiz before subscribing; plans are purchased through the extension or mobile apps. Check the official site for the latest prices and tiers.

- **Key Ideas Extraction:** Get the essential points from any topic and length of video as a short list or a detailed breakdown, without watching the whole thing.
- **Timestamped Summaries:** Each summary point carries a timestamp that links back to the moment it came from, so you can verify or jump straight to the relevant section.
- **Video to Text Transcripts:** Convert YouTube audio into accurate, readable text that you can scan, quote, or use as notes for research and study.
- **41-Language Support:** Summarize and translate content across 41 languages, making international lectures, interviews, and creators accessible in your own language.
- **Browser Extension and Mobile Apps:** Summarize directly on YouTube from the extension, or on the go with the dedicated iOS and Android apps, so learning fits wherever you are.

**Strengths:** Summarizes on YouTube itself, with no tab switching or prompt writing; Timestamped summaries make it easy to verify and jump to source moments; Handles very long videos up to about 12 hours, including podcasts; Companion iOS and Android apps extend it beyond the desktop browser
