Make English easier to read and understand. Real language learning starts with content you actually love. Learn English with what you already want to read: your favorite novels, long-form articles, and web pages you come across. SentiaRead turns these materials into your most effective learning resources, removing reading friction and vocabulary barriers so you acquire English naturally in flow. Why reading in English often feels exhausting: • Looking up words breaks your focus: Regular dictionaries list dozens of definitions, leaving you to guess which one applies while your train of thought vanishes. • Knowing every word but missing the sentence: Complex nested clauses leave you re-reading the same line without understanding, and machine translations sound clunky and unnatural. • Look up, forget, repeat: Words you memorized on flashcards vanish in real articles, and words you looked up two pages ago feel completely foreign again. SentiaRead removes the comprehension barriers so you can keep reading effortlessly: 【In-Context Word Lookup · No More Guesswork】 Tap any unfamiliar word. AI analyzes the full sentence context and your English level (CEFR A1 to C2) to deliver the exact meaning that fits, complete with a clear example. Explained in simple English first to build natural intuition, with native translations always available as a quick check so your reading flow stays uninterrupted. 【Sentence Simplifier · Understand Complex Syntax】 Stuck on a convoluted sentence or dense paragraph you've re-read three times? Select it, and AI faithfully rewrites it into clear, simple English broken into natural thought groups while preserving every original detail and nuance. Key vocabulary is highlighted for one-tap saving, with natural sentence translations available to assist comprehension. 【Vocabulary Follows You · Natural Retention】 Saved words stay highlighted across every book and article you open, complete with concise inline meanings so you recall them instantly without repeated lookups. Encountering vocabulary across authentic reading builds lasting familiarity naturally, with no mindless flashcard grinding. 【Scientific Vocabulary Review · FSRS & Word Radio】 • Smart Spaced Repetition: Powered by the state-of-the-art FSRS (Free Spaced Repetition Scheduler) algorithm, scheduling reviews dynamically based on your retention so you review at the optimal time. • Exclusive Word Radio: Turn your vocabulary list into a hands-free audio stream with background and lock-screen playback. Listen to words, context sentences, and bilingual definitions during commutes and walks. 【Open and Read · Your Personal English Library】 • Built-in curated reads and instant access to 70,000+ public domain classics, from The Great Gatsby to Pride and Prejudice. • Import your own EPUB, PDF, TXT, or Markdown files, turning what you genuinely want to read into your best learning materials. 【Seamless Sync Across All Devices】 Reading progress, highlights, and vocabulary sync automatically in real time across iPhone, iPad, Android, desktop, and E-Ink devices (like Onyx Boox).
