About this app

BookNPC turns your eBooks into dynamic audiobooks with smart, multi-voice AI narration. Just import your EPUB, Kindle (MOBI, AZW), TXT or FB2 files and hear your stories come alive with distinct voices for each character. Prefer a simpler experience? Switch to narrator-only mode for hands-free reading anywhere, with offline playback using your device's built-in voices or our natural-sounding English AI voices. TTS playback is free, and full-cast processing is affordable. Converting the entire Alice's Adventures in Wonderland into a full-cast audiobook costs less than 30 cents.
