Readlate is a private document reader for people who read books, articles, notes, and handouts in another language. Open a file, translate the whole document with Apple Translation, then switch between the original and translated version whenever you need context. READ FOREIGN DOCUMENTS MORE COMFORTABLY Readlate is built for foreign-language reading, not quick phrase lookup. Keep your place, return to recent documents, and continue reading after translation without rebuilding your library. SUPPORTED FILE TYPES Open EPUB, PDF, DOCX, TXT, Markdown, HTML, and JSON files from the Files app, iCloud Drive, email attachments, or any document source available on iOS. WHOLE-DOCUMENT TRANSLATION Translate full documents with Apple's Translation framework. Language packs can be downloaded from iOS, so supported language pairs can work offline after the required packs are installed. ORIGINAL / TRANSLATED READING Switch between the original document and the translated version while keeping your reading position. This is useful when you want to check wording, compare meaning, or continue reading in the language that feels easiest. RECENT DOCUMENTS THAT STAY ORGANIZED Return to your current books and documents from the recent library. Format badges, translated-language labels, and reading progress help you pick up where you left off. READER TOOLS • Page and continuous scroll reading modes • Adjustable font size and font family • Table of contents navigation • Full-text search • Bookmarks • Custom tap-zone actions • Chapter and paragraph re-translation tools EXPORT TRANSLATED FILES Save translated results back to the Files app. EPUB and DOCX exports keep their document-oriented workflow so translated material is easier to review or reuse. PRIVACY-FIRST BY DESIGN Files are imported and read on your device. Standard translation uses Apple Translation and can work offline with the required language packs. When you choose Premium Translation, the text to be translated is sent through Readlate's server to a cloud AI translation provider; an internet connection is required. Readlate does not require you to create an account. SUPPORTED INTERFACE LANGUAGES Readlate is localized in English, Korean, Japanese, Simplified Chinese, Spanish, French, German, and Portuguese (Brazil). READLATE PRO — ONE-TIME PURCHASE The free experience includes ads and parallel original/translation reading. A one-time Readlate Pro purchase removes ads and reward gates and unlocks bilingual export. Cloud translation is subject to usage limits; Pro does not include unlimited cloud translation. PREMIUM TRANSLATION — AUTO-RENEWING SUBSCRIPTION Premium Translation adds high-quality cloud AI translation for long books and includes every Readlate Pro feature. Two plans are offered: Premium Translation Monthly (1 month) and Premium Translation Yearly (1 year). The price of each plan is shown in the app before you purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. You can manage or cancel it any time in your App Store account settings.

Read books. Learn languages. Read the original. Compare translations. Understand more with AI. ReadGem turns reading into a natural way to learn languages. Explore the original text alongside its translation, compare how the same sentence is expressed across languages, and discover meaning through real books and real context. When a sentence is difficult, ask AI for an explanation. When a translation feels awkward, use AI to suggest a better one. Go beyond simply reading a translation — read, compare, understand, and learn. Read the original and translation together Explore the original text alongside its translation and see how meaning moves from one language to another. Instead of studying isolated words and grammar, experience language through real sentences, expressions, and context from books. Reading becomes learning naturally. Compare translations across languages See how the same sentence is expressed in different languages. Compare translations sentence by sentence and discover differences in wording, expression, and nuance. Whether you're learning English or exploring another language, ReadGem helps you see beyond a single translation. Understand more with AI Some sentences need more than a translation. Ask AI to explain difficult sentences, expressions, context, and nuance. Explore why a sentence means what it does and gain a deeper understanding of both the original text and the language you're learning. Use AI not just to get an answer, but to understand what you're reading. Improve translations with AI Found a translation that sounds awkward or doesn't fully capture the original? Ask AI to suggest a better translation. Compare the suggestion with the original and decide whether it expresses the meaning more naturally and accurately. Exploring better translations can itself become part of learning a language. Read and listen Listen to sentences while you read. Hear pronunciation and rhythm while following the text, and use books to practice listening and pronunciation as well as reading. Everything you need for EPUB reading ReadGem also includes essential EPUB reading features: Table of contents and chapter navigation Highlights and bookmarks Automatic reading position saving Font and reading appearance settings Offline reading for downloaded books ReadGem is for you if you want to: Learn English by reading original books Learn languages naturally through reading Read original text alongside translations Compare expressions across different languages Understand difficult sentences with AI Explore better translations with AI Read.
