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.
Learn languages from Netflix, YouTube, and real-world texts with dual subtitles and AI
View your target language together with a translation, pause, replay single lines, and jump back to the previous subtitle with a hotkey.
Hover or click any subtitle word to see definitions, part of speech, and pronunciation without leaving the video.
Automatically saves looked-up words and phrases, then quizzes you with the original context to build durable recall.
Bring the same translation and lookup workflow to ebooks, PDFs, articles, and other web pages.
