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 [Profile (Markdown)](https://openaitools.app/tool/glasp.md) ## Memdex Memdex addresses a very practical daily annoyance: your best prompts, project background, and decisions are scattered across dozens of separate AI chats that each forget everything the moment you open a new thread. Instead of re-explaining your stack, your style, or your constraints every single time, Memdex builds a personal memory layer that travels with you between AI tools. The extension auto-saves your conversations as you work, indexes them into a searchable local library, and then injects the relevant slices of context into whatever chat window you happen to be using. Because the memory store lives on your own device, the promise is that your private work discussions never get shipped off to a third-party server just to be remembered. It is aimed at developers, writers, researchers, and power users who juggle several models at once and want continuity rather than cold starts. The trade-off is familiar for local-first tools: you get privacy and control, but the quality of retrieval depends on how consistently you use and curate the extension. **Pricing & Plans:** Freemium. The extension is installable and usable without payment, with a free tier covering core saving and recall. A paid tier is offered for heavier usage; check the official site for current limits and prices since exact figures are not published on the homepage. - **Automatic conversation capture:** Your chats in ChatGPT, Claude, Gemini and other AI tools are saved in the background without you having to copy-paste anything. - **Local-first storage:** Memories are kept on your own device, so sensitive project context stays under your control rather than in a vendor cloud. - **Context injection:** Pull a previous conversation, snippet, or project brief straight into a new chat so the model starts with your background already loaded. - **Searchable memory library:** Browse and search everything you have saved to find that one prompt or decision you half-remember. - **Multi-tool portability:** Move context between different AI assistants, so switching models doesn't mean starting from zero. **Strengths:** Saves AI conversations automatically so you never lose a good prompt; Local storage model appeals to privacy-conscious users; Works across several major AI assistants instead of locking you into one; Injected context cuts down on repetitive re-explaining **Limitations:** Retrieval quality depends on consistent curation of your memory bank; Requires installing and trusting a browser extension with your chat data; Exact free-tier limits and paid pricing are not clearly published on the homepage [Profile (Markdown)](https://openaitools.app/tool/memdex.md) ## Frequently Asked Questions ### How do Glasp and Memdex compare in monthly traffic?
