Summaries can be exported as PDF or EPUB, and there is a mobile app alongside the web reader. Discovery is organised by theme, curated lists, trending, new releases, genre and author, with an import path for existing reading lists, bookmarks, history, ratings and personalised recommendations behind a free account, plus the ability to request summaries of books not yet covered. A gift option and an affiliate programme are both published.
