Highlight the web, learn in public, and build your AI clone
Mark up passages on any website or lines in a YouTube transcript from a browser extension, then keep them in one searchable library.
Highlights are shared publicly by default, so you can follow other users, react to their picks and discover sources through people with similar interests.
Generate summaries of long articles, PDFs and YouTube videos to judge relevance fast and to digest what you have already saved.
Trained on your accumulated highlights and notes, the AI clone answers in the shape of your reading history and areas of interest.

Highlight any passage, right-click, and get a ChatGPT-powered summary in a pop-up
Highlight text, open the context menu, and pick SimpliSum to generate a summary without leaving the page or switching tools.
Results appear in a small pop-up over the current page, so you can compare the condensed version against the original passage side by side.
The listing describes summaries built on advanced machine-learning and natural language processing techniques powered by ChatGPT.
Rather than truncating, the extension is designed to identify the most important ideas, concepts, and details in the selected text.
