Track your reading progress and explore only what you have read already, without any spoilers.
The story, the characters, the ideas and the answers, all following your bookmark, so you understand what you read without spoiling what comes next
Track your reading progress, and the characters, locations, plot events and answers to your questions stay hidden until you reach the chapter that reveals them.
Get to know the characters of a novel with portraits and profiles, see how they relate to each other and where the story takes place, and follow the plot on a timeline you can search and filter.
Chat with the characters of a novel, who answer in their own voice, and know only what you have read so far.
Browse the key takeaways of a non-fiction book, check off its actionable insights, look up its concepts in a glossary, and find the other resources it recommends.
Ask about the contents of your book, or an explanation of a concept, and get answers based on the book. With links to the chapters they come from.
Write rich notes on your books that reference chapters, characters and locations, and with Pro, let the assistant turn your chats into notes and export everything to Markdown for Obsidian, Notion or Logseq.
Read the summaries and everything else in your own language, or in the language of each book.

Whether you can download a DRM-free ePUB of a book depends on the store you bought it from, and on whether its publisher chose to sell it without DRM:
If your store doesn't offer a DRM-free copy, many publishers and authors sell DRM-free ePUBs on their own websites. Public domain classics are available as DRM-free ePUBs from sites like Project Gutenberg and Standard Ebooks.
