Turn any EPUB or PDF into a natural-sounding audiobook — fully offline, and free to start. Éist reads your ebooks aloud with on-device AI voices, and its read-along mode highlights every word in sync with the audio.

Éist (pronounced "esht", Irish for "listen") is a text-to-speech audiobook reader. Import an EPUB or PDF, pick a voice, press play. Your books stay on your device and work with no internet once a voice is downloaded. No ads, ever.

★ READ ALONG AS YOU LISTEN
Éist's read-along mode shows each word one at a time, perfectly in sync with the voice, with the focal letter highlighted — so your eyes follow the text as you listen. Tap the bolt icon to switch read-along on, and use the sync dial to fine-tune the timing. Read-along is great for focus, following along, dyslexia support, and language learning.

★ LISTEN TO ANY EPUB OR PDF
Import any EPUB or PDF ebook and Éist reads it aloud with remarkably natural text-to-speech voices. Perfect for commutes, workouts, chores, studying, or winding down at the end of the day. Turn the documents and ebooks you never find time to read into audiobooks you can listen to anywhere.

★ NATURAL AI VOICES
Choose from 60+ on-device AI voices across three text-to-speech engines — Kokoro, Piper and Supertonic — in dozens of languages. Each voice has its own character and accent. Preview any voice before you commit, and switch narrators any time mid-book.

★ SMART AHEAD-OF-PLAYBACK SYNTHESIS
Éist generates audio ahead of where you are listening, so playback stays seamless. Chapters you have already heard replay instantly from your device.
