Éist: Turn any EPUB or PDF into an audiobook
The free offline text-to-speech app that converts your ebooks into natural audio. No internet required, no ads, unlimited listening forever.
The complete EPUB to audiobook solution
Eist combines powerful text-to-speech technology with thoughtful design to create the best offline audiobook experience for your own books.
Advanced AI Text-to-Speech Engine
Natural, expressive narration
Eist uses state-of-the-art on-device AI to convert your ebooks into natural-sounding audio. Unlike robotic screen readers, our text-to-speech engine understands context, handles punctuation naturally, and delivers expressive narration that makes listening enjoyable for hours. Choose from multiple voice options with different accents, genders, and speaking styles to find your perfect narrator.
EPUB and PDF Support
Import any ebook format
Bring your entire ebook library into Eist. We support EPUB files with full chapter detection, bookmarks, and metadata extraction. PDF support means you can listen to documents, textbooks, and scanned books too. Plus, browse over 70,000 free public domain classics from Project Gutenberg directly in the app - from Pride and Prejudice to Sherlock Holmes.
Full Playback Control
Listen your way
Take control of your listening experience with adjustable playback speeds from 0.5x to 3x. Set sleep timers for bedtime listening, create bookmarks to save your place, and navigate easily between chapters. Background playback lets you listen while using other apps, and the lock screen controls keep you in command without unlocking your phone.
100% Offline Capability
No internet required
Once you download your preferred voices, Eist works completely offline. All text-to-speech processing happens on your device - no cloud, no streaming, no data usage. Perfect for flights, subway commutes, camping trips, or anywhere with spotty reception. Your books are always available, and your reading habits remain completely private.

Complete Privacy

Why this matters: Cloud-based services like ElevenLabs and Speechify send every word of your book text to their servers—that's a privacy concern for personal books and manuscripts.
