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 sentence, get an instant, page-aware AI explanation
Highlight a confusing sentence and receive a short explanation without leaving the page or opening another tab.
Choose how much surrounding page text is sent along with your selection to balance answer quality against API cost.
When a selection plus page context exceeds the request size limit, the extension automatically lowers how much page content it ingests.
Accidental highlights created by double-clicking are ignored, so the tool only fires when you deliberately select text.
