## 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

## Lexal

Lexal takes a deliberately lightweight approach to AI in the browser. Rather than opening a chat tab, it rides on the right-click context menu: select a sentence, choose a function, and Gemini responds in a small overlay. That keeps you in the flow of whatever you are reading instead of switching between windows.

The extension bundles four related reading aids. Fact check tests a claim against the model's knowledge; Bias check examines how a piece of writing frames its subject; Summarise/TLDR compresses long content into a short overview; and the debate mode deliberately argues both for and against a proposition, which is useful for pressure-testing an argument before you repeat it. All of these return output in the browser's current language.

Architecturally, Lexal is honest about what it is: a standalone wrapper around a large language model. It does not run its own inference or resell tokens — you paste in your own Google Gemini developer API key, and the extension simply calls that model under your own quota. The developer states that no user data is collected, sold or shared, which is a sensible posture for a tool that needs access to whatever text is on your screen. It is a small, focused utility rather than a full AI assistant, and it is best judged as such.

**Pricing & Plans:** Free. Lexal is a standalone wrapper that runs on your own Google Gemini developer API key and does not charge for tokens; you only pay Google if you exhaust the free Gemini credit allowance.

- **One-click fact checking:** Select any statement and get Gemini to verify whether a specific claim holds up, right inside the page you are reading.
- **Bias detection:** Scan an article and have the model call out framing, slant and potential bias so you can read more critically.
- **Summarise / TLDR:** Condense long articles, threads or documents into a short TLDR you can skim in seconds.
- **Two-sided LLM debates:** Generate balanced, well-reasoned arguments for and against a topic to stress-test your own position.
- **Browser-language output:** Outputs are returned in your browser's language, so the tool fits naturally into a multilingual browsing session.

**Strengths:** Completely free, with no token markup or subscription; Runs on your own Gemini API key, so there is no third-party data middleman; Right-click workflow keeps you inside the page you're reading; Combines four distinct reading aids — fact check, bias check, summary and debate — in one small extension

**Limitations:** Tiny user base and no reviews, so reliability feedback is limited; Requires you to obtain and manage your own Gemini API key; Last updated in July 2024, so it may not track the newest Gemini models; Right-click only workflow — no persistent sidebar or full-page interface
