Reader AI: Read & Learn

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 reads the word in context to show how it is actually used. 【Sentence & Passage Explanations】 Select a sentence or passage and tap "Explain with AI" to understand sentence structure, idioms, expressions, and cultural context. Set your native language and proficiency level to get explanations that fit you. 【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 App Store accounts outside mainland China. Turn your books into audiobooks. Preview and choose a narrator voice, follow along with a synchronized transcript, and add a subtitle translation. Switch seamlessly between reading and listening at the same sentence, with your listening position synced via iCloud. 【Pronunciation & Study Book】 Listen to the pronunciation of words and phrases, and save expressions you want to remember. Your Study Book 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 typography, and set Appearance to Follow System, Light, or Dark. 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 works only if the file has 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 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 only and may contain errors. 【Free Reading & Pro】 Reading, highlighting, note-taking, and PDF annotation are free. The free version's Bookshelf holds up to 3 books (imported, from Library Sources, or added from Discover); books opened with Start Reading in Discover don't count. No bookshelf limit (one-time purchase) or Pro removes the limit. Free AI credits are included so you can try contextual word lookup and sentence and passage explanations. Once they are used up, you need Pro to keep using these AI features and to see AI-generated definitions in your Study Book. 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 subtitle translations are purchased separately with credits (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.
