Finally finish the books you keep meaning to read. We all have a someday pile: the classic that's hard going in English, the PDF a friend sent you, the book you started and never finished. Librai helps you actually finish them. Read any book in your language, listen to it with every word lit up, and ask an AI that reads along with you. READ IT IN YOUR LANGUAGE Open any EPUB or PDF and Librai turns the page you're on into Spanish, Hindi, Chinese, Arabic, French, Portuguese, German, Japanese, Korean or one of 23 languages in all, including Hinglish. It's the real page, sentence by sentence, not a summary. Tap the language chip to see the original whenever you like. Five translated pages a day are free. LISTEN TO ANY BOOK Turn any book into an audiobook with Apple's natural voices, right on your iPhone. Every word lights up as it's read, the page turns by itself, and it keeps playing from the mini player when you close the book or lock your phone. Set the speed, skip back 15 seconds, or use a sleep timer. Listening is free with no limits. ASK IT ANYTHING. IT DOES THE WORK. Select a passage and tap Ask, or open Ask Librai from the menu. The AI searches the whole book, explains a passage, turns to the page where something happened, and can highlight the key lines or save a note for you. Every change it makes comes with Undo. It only uses what you've already read, so it never spoils the ending. BUILT TO HELP YOU FINISH β€’ Story so far: come back after a few days and get a quick, spoiler-free recap of what you've read β€’ Reading plans: "Finish this in 2 weeks" gives you a small daily page goal and an evening reminder β€’ Book brief: finish a book and get one page of its key ideas and your own highlights, ready to share A CHAT THAT KNOWS YOUR LIBRARY Ask Librai what to read next, what you've highlighted in a book, or how your reading is going this week. It recommends real books as cards you can add in one tap, and can mark books finished, rate them, make collections and set reading plans for you.

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 β€” 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.
