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.

No subscription. No ads. No account. No AI. Eluna Reader opens almost any book or document — over 20 formats — and keeps every page, note and bookmark on your own device. Most reading apps rent you your own library. Eluna never does: reading is free, the only purchase is a one-time tip that unlocks nothing, and anything you write stays yours. READS 20+ FORMATS EPUB (2 & 3), FB2, FB3, MOBI, AZW3, PRC, PDF, DjVu, DOC, DOCX, ODT, RTF, TXT, Markdown, HTML, CHM, UMD and comics (CBZ, CBR, CBT) — even books inside ZIP archives. One shelf for novels, manga, manhwa, textbooks and PDFs alike. READ-ALOUD & REAL PAGE NUMBERS Listen to any book with the built-in read-aloud voice, the current sentence highlighted as it speaks. See real page numbers — "page 128 of 512" — not just a percentage, in a status bar you assemble yourself. TYPESET IT YOUR WAY Paged mode with slide, fade and 3D page-turn animations, or a smooth continuous scroll. Portrait or landscape, two-page spread on a tablet. 5 bundled fonts including OpenDyslexic, or import your own TTF/OTF. Fractional font size, four independent margins, line and paragraph spacing, hyphenation. Keep the publisher's own CSS, or force your own styling on top. NOTES THAT LEAVE THE APP Highlight in many colors, tag notes with hashtags, pin and group them into a second brain. Export the whole library to Markdown, Obsidian, Readwise, JSON or CSV — and import it back. Your annotations belong to you, not to a database. SYNC WITHOUT AN ACCOUNT Reading position, highlights, notes and reading statistics stay in step across iPhone and iPad through your own iCloud — encrypted end to end, no server, no sign-up. Speak KOReader's sync protocol (KOSync) or point it at your own WebDAV folder to plug into Kavita, Komga or Calibre-Web. FIND ANYTHING Full-text search across every book, inside PDF pages, and through all of your notes at once. On-device OCR reads scanned PDFs so even they become searchable — nothing is ever uploaded. BUILT FOR LONG READING Automatic day and night, sepia, OLED-black and e-ink themes. Blue-light filter, on-screen reading ruler, brightness control and auto-scroll. Remap tap zones, swipes and the volume keys. Dictionary and translation on any word — strictly opt-in. Browse OPDS catalogs and your own servers. PRIVATE BY DEFAULT Works fully offline. No trackers, no telemetry, and no AI trained on your books. Optional Face ID / Touch ID lock and screenshot protection. Every connection the app can make is listed on a single screen. 61 LANGUAGES, 63 BADGES The whole app is translated into 61 languages. Reading statistics, daily streaks and 63 achievement badges keep the habit going. Eluna Reader — a power reader that respects your library and your privacy.
