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.
