The future of AI is private and on-device — and LysnBox brings it to your reading. It transforms your digital library into a premium, clutter-free listening experience, using modern on-device AI voice synthesis to read your EPUBs, PDFs, and web articles aloud in remarkably natural, expressive voices. No cloud. No account. No compromise.
Why you'll love LysnBox:
YOUR LIBRARY, IMPORTED IN SECONDS
Bring DRM-free EPUBs, PDF documents, or any web article into a polished, distraction-free reader. Everything stays organized in one place — and resumes exactly where you left off.
NEXT-GENERATION ON-DEVICE NARRATION
Forget the flat, robotic voices of old text-to-speech. LysnBox runs high-fidelity neural voice models directly on your iPhone's Neural Engine — smooth, human-like narration built for long-form listening, now in 31 languages, from English, Spanish, and French to Japanese, Korean, Hindi, Arabic, and more.
WORD-LEVEL HIGHLIGHTING & SPEED CONTROL
Follow along with precise, synchronized word highlighting. Adjust playback from 0.8x to 2.0x, pitch-preserving — no distortion, no chipmunk effect.
BEAUTIFUL, MODERN DESIGN
Curated light and dark themes, glassmorphic typography, fluid animations, and Lock Screen and Bluetooth controls for effortless background listening.
TRULY PRIVATE — OFFLINE-FIRST BY DESIGN
In an era where most AI sends your data to the cloud, LysnBox does the opposite. Every word is synthesized entirely on your device — no tracking, no accounts, no uploads, and no internet required to listen.
Your library. Your voice. Your device. Start listening with LysnBox today.
