## 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

## MemBrain - AI-powered Second Brain

MemBrain is a Chrome extension that places an AI assistant in the browser's side panel. Rather than switching tabs to a chat website, you can open the panel and talk to an AI model while the page you are reading stays visible next to it. It is positioned as a lightweight 'second brain' for research and browsing, and the project is open source.

The extension focuses on flexible context. You can add one or more web pages, or selected passages of text, as references for the model, so answers are grounded in the material you are actually looking at rather than generic knowledge. It ships with integrations for several popular AI providers and models, and because it is built around standard API formats you can add further providers or models yourself. Prompt templates can also be saved so common tasks are one click away.

Privacy is a stated design principle: the extension runs without any intermediary server and communicates directly with the model providers using the API keys you supply. According to the developer, it does not collect, store, or share personal information, browsing history, API keys, or chat history. MemBrain is distributed through the Chrome Web Store and is free to install.

**Pricing & Plans:** Free. MemBrain itself is a free, open-source Chrome extension; costs come from the AI provider API usage you pay for directly with your own API keys.

- **AI chat in the Chrome side panel:** Open an AI chat alongside the page you are reading, without navigating away or switching tabs.
- **Web pages and text as context:** Attach one or more pages, or selected passages, as references so answers draw on your actual source material.
- **Bring your own API keys:** Connect directly to providers such as OpenAI, Anthropic, and Google using your own keys, and add more providers that follow supported API formats.
- **Reusable prompt templates:** Save prompt templates to run frequent tasks in a single click.
- **No intermediary server:** The extension talks straight to model providers and, per the developer, does not collect or store your data, keys, or chat history.

**Strengths:** Keeps AI chat in the browser side panel next to your content; Supports multiple AI providers through user-supplied API keys; Open source and, per the developer, operates without a backend server; Custom prompt templates and self-added models add flexibility

**Limitations:** No bundled AI credits, so you must set up your own provider API keys; Very small install base, so community support and documentation are limited; Last listed update is v0.4, so the release cadence appears slow
