Librai: AI Book & PDF Reader

Translate, listen & finish it

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Every book in your language, read aloud, with an AI that reads along. Story so far, reading plans and briefs help you finish. 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 • Story so far: come back after a few days and get a quick, spoiler-free recap of what you've read • Reading plans: "Finish this in 2 weeks" gives you a small daily page goal and an evening reminder • 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.

Smoother reading in this update: we fixed a handful of bugs and polished the details, so the reader menu, Ask Librai and Story so far feel faster and more reliable. Thanks for reading with Librai!
