Local Narrator
Read full descriptionHide full description
Your books, read aloud — privately, on your iPhone. Local Narrator turns any EPUB or text-based PDF in your library into a real audiobook, narrated by a warm neural voice that runs entirely on the Apple Neural Engine. Nothing leaves your device. There is no cloud. There is no account. There is nothing to opt out of. — BRING YOUR OWN BOOKS — Drop in EPUB or PDF files from the Files app, the share sheet, or AirDrop. Your books stay on your iPhone, and the audio they become stays there too. No upload, no forced sync, no backup you didn't ask for. — A REAL NEURAL NARRATOR — Local Narrator runs Kokoro-82M, a state-of-the-art on-device text-to-speech model, on the Apple Neural Engine. The voices are warm, natural, and quietly expressive. When you'd rather not download the model, Apple's built-in system voices work for free. — BILINGUAL, AND SMART ABOUT IT — English and Spanish. Local Narrator detects each book's language and picks a voice trained for it. Spanish voices are still in beta stage. — LIKE AN AUDIOBOOK SHOULD BE — • Background playback that doesn't stop when the screen sleeps • Lock-screen controls — play, pause, +30, −15, scrub • Home and Lock-screen widget with a clean amber progress ring • Sleep timer for reading yourself to sleep • Per-book reading position, automatically saved • Unlimited bookmarks • Adjustable speed from 0.5× to 3.0× • Light parchment or dark charcoal reading themes • Full Dynamic Type and VoiceOver support — PRIVATE BY DESIGN — No accounts. No telemetry. No advertising SDKs. No third-party trackers. The only network call the app ever makes is the optional, one-time download of the Kokoro voice model. After that, everything works in airplane mode. — ONE PURCHASE. YOURS FOREVER. — Free to download and try with one book and Apple's system voices. A single $4.99 in-app purchase ("Local Narrator Full Access") unlocks unlimited books, all neural voices, the full speed range, the widget, the sleep timer, and unlimited bookmarks. No subscription. Family Sharing supported. — BUILT FOR REAL iPhones — iOS 17 and newer. iPhone 15 or later (Pro version recommended), optimised for the Apple Neural Engine. A small, careful app for people who still read.

Read the books you actually want to read. Learn a language through the original text. Reader AI is an AI-powered reader that helps you understand words, sentences, and passages in context. Import your own books, get explanations right where you're reading, chat with AI about what you've read, or switch to listening, all without losing the flow of the original text. 【Vocabulary in Context】 Press and hold a word to see what it means in the current sentence. AI interprets the word based on its context, helping you understand how it is actually used. 【Sentence & Passage Explanations】 Select a sentence or passage and tap "AI Explain" to understand sentence structure, idioms, expressions, and cultural context. Set your native language and proficiency level to receive explanations tailored to your needs. 【Book Chat】 Ask AI about the book you're reading: characters, plot, themes, or a passage you're stuck on. Answers cite the original passages they're based on. 【Audiobooks】 Available for non-mainland China App Store accounts. Turn your books into audiobooks. Preview and choose a narrator voice, follow along with a synchronized transcript, and add translated subtitles. Switch seamlessly between reading and listening at the same sentence, with your listening position synced via iCloud. Audiobooks are currently available for App Store accounts outside mainland China. 【Pronunciation & Learning Notebook】 Listen to the pronunciation of words and phrases, and save expressions you want to remember. Your Learning Notebook keeps the definitions and example sentences from when you saved them. Filter saved items by book or type, and jump back to the original passage at any time. 【Your Books, Your Way】 Import EPUB, TXT, MOBI, PDF, AZW3 and other supported formats. Add highlights and notes, customize your reading layout, and choose between System, Light, and Dark appearances. View your bookshelf as a grid or list, manage books in bulk, and pick up where you left off from Home. Annotate PDFs with handwriting and text, and export them with annotations. For scanned PDFs, word lookup depends on whether the file contains selectable text. 【No Account Required】 Start reading as soon as you open the app. Your books, reading progress, and learning data are primarily stored on your device and in your personal iCloud storage. When you use AI features, the selected text and necessary surrounding context may be processed to provide the requested result. Creating an audiobook processes the chapter text to generate narration. AI-generated content is for reading and learning purposes only and may contain errors. 【Free Reading & Pro】 Importing books, reading, highlighting, note-taking, and PDF annotation are free. Free AI credits are included so you can try contextual word lookup and sentence and passage explanations. Once your free credits are used, a Pro subscription is required to continue using these AI features and to view AI-generated definitions in your Learning Notebook. Pro includes unlimited word lookup, sentence and passage explanations, pronunciation, and Book Chat. Monthly, three-month, and annual auto-renewable subscription options are available. Prices are shown on the purchase screen. Audiobooks and translated subtitles are purchased separately with credits, available as in-app purchases. The cost is shown before you buy. Payment will be charged to your Apple Account upon confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current subscription period. You can manage or cancel your subscription in your Apple Account subscription settings, and restore previous purchases from within the app. Please only import books and other content that you have the right to use.

Verdict
The clearest difference is update cadence: Reader AI at every 6 days against Local Narrator's monthly. Reader AI also leads on iOS requirement (16.0 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
