BookNPC is an audiobook maker. Listen to a growing library of ready-made audiobooks for free, and turn your own eBooks into full-cast audiobooks where every character has its own voice. A GROWING FREE LIBRARY Sign in for free and start listening. Discover has a growing library of ready-made audiobooks, some with a full cast, and new titles arrive every day. Listening time for these books is free and refills every day, and a short ad adds more. TURN YOUR BOOKS INTO AUDIOBOOKS Import your EPUB, Kindle (MOBI, AZW), TXT, or FB2 files and turn them into audiobooks with text-to-speech. Make a full-cast audiobook, where AI works out who is speaking and gives each character its own voice, or have the book read aloud in a single narrator voice. 300+ CLOUD VOICES Cast a book in the cloud with more than 300 high-quality AI voices, in English, Chinese, Japanese, Korean, German, French, Spanish, Italian, Portuguese, and Russian. AI gives each character a voice that fits their gender and age. You can also play a full cast or a single narrator on your device, with the voices already on your phone. READ IN ANOTHER LANGUAGE Translate a book as you listen, powered by our AI models, and match the voices to the language you are reading in. PRICING The Discover library is free to listen to. On your own books, a single narrator in the book's own language plays free on your device, offline. Full cast and translation use AI to read each page, and cloud voices are made on our servers. Those are paid with credits (G), bought in one-time packs that never expire, and new accounts start with 2 G. Before a cloud cast starts, you see what it will cost and can pick the page it starts from. An optional Ad-free subscription, monthly or yearly, removes ads and the daily listening limit on Discover books. PERFECT FOR People who would rather listen than read Readers who want a theater-like, multi-voice audiobook Anyone who wants an audiobook of a book they already own Note: You are responsible for making sure you have the rights to the content you use with BookNPC.
