Infinite Library is where books get written, read, and held. WRITE — THE BINDERY STUDIO Tell the editor your idea and it writes and typesets a complete, print-ready book with you — real pages, a designed cover, yours to own. Watch it draft chapter by chapter, answer its questions, ask for changes in plain language, and rewind to any earlier version. Start from a sentence, a pile of notes, a manuscript, or a YouTube link. On iPad and Mac the live typeset proof sits beside the conversation. Free to start, no account required. READ — THE WHOLE LIBRARY Thousands of books by real people, browsable by shelf and searchable, in a reader made for reading: paper, sepia and night pages, your type size, and your place remembered — pick up where you left off from the Continue reading shelf. Hide any book, block any author, and report anything that shouldn't be there. Follow an author from any book's page, and their next book finds your inbox. HOLD — REAL PAPERBACKS Order the printed edition of any book on the print shelf — including your own — with a live shipping quote, then follow it to your door from Account. LISTEN Albums written from books, audiobook samples, and the audiobooks you own — with lock-screen controls and playback speed. Narrate your own book and watch it record itself, chapter by chapter, live on your Lock Screen and in the Dynamic Island. YOUR ACCOUNT Sign in with a one-time email code — no password to remember.
