LysnBox: Turn books, PDFs & articles into audiobooks, fully offline

Hi Product Hunt! 👋 I built LysnBox because I had a growing pile of EPUBs, PDFs and saved articles and never enough time to sit down and read them. Existing read-aloud apps either sounded robotic or sent my books to a cloud API and charged per minute. So LysnBox does everything on-device: • Import an EPUB, PDF, web link or pasted text and tap play, with no conversion step • Natural AI narration in 31 languages, powered by Supertonic 3 on the Apple Neural Engine • Nothing leaves your phone and no audio is stored to disk • Word-level highlights, 0.8x–2x speed, and it resumes exactly where you left off • Lock screen and Bluetooth controls for listening on the go It's free on the App Store and fully open source (MIT), so you can build it yourself too. I'd love your feedback: which voices, languages or formats should I add next?
