Éist: PDF/Ebook to Audiobook

Turn any EPUB or PDF into a natural-sounding audiobook — fully offline, no subscription required to listen.

Éist (pronounced "esht", Irish for "listen") uses on-device AI voices to read your ebooks aloud. Import a file, pick a voice, press play. Your library stays on your device. No internet required after a voice is downloaded. No ads. No tracking.

LISTEN TO ANY BOOK
Import any EPUB or PDF from your device, and Éist reads it aloud with remarkably natural AI voices. Perfect for commutes, workouts, household tasks, or winding down at the end of the day.

EXPRESSIVE AI VOICES
Choose from a curated selection of on-device voice engines — Kokoro, Piper, and Supertonic. Each has a distinct character and accent. Preview before you commit, and switch any time mid-book.

SMART AHEAD-OF-PLAYBACK SYNTHESIS
