You don't just read. You disappear into books. RookReader is built for that. Beautiful typography, immersive themes, nothing standing between you and the story. EVERY BOOK. ONE APP. EPUBs, PDFs, comics, web serials, whatever format it arrives in. Pull them from Files, iCloud Drive, Google Drive, Dropbox, Calibre-Web or any free catalog. One shelf for everything you own, sorted into collections and smart shelves that fill themselves. Don't own it yet? Scan the barcode or paste a link and it waits on your Want to read list until the file is real. Out of books? Over 20,000 audiobooks are already inside, free. MEET ROOK AI Forgot who that character is? Lost the thread three chapters back? Just ask. Rook AI has read every page you have and not one page more. Zero spoilers, ever. It catches you up, explains what just happened, and still remembers the character introduced 200 chapters ago. Bring your own key (Claude, OpenAI or any compatible provider) so your books stay between you and your provider. READING THAT FEELS LIKE READING • Eight reader themes, from crisp white to warm sepia to true black • Your font, size, spacing and margins, saved as profiles you switch in a tap. Import your own typefaces too • Turn pages by swipe, scroll or tap, wherever your thumb already rests • Auto-scroll that flows at your pace, so you never lift a finger • Bionic reading bolds the start of each word so your eyes glide instead of grind • Speed reading feeds you one word at a time when you want to move • Ambient rain, cafe hum and cinematic calm playing under the page • Vertical text for CJK, and clean-up for curly quotes and ALL-CAPS shouting "WAIT, WHERE WAS THAT SCENE?" You remember the moment, not the page. Describe it, like "they argued on the rooftop in the rain", and RookReader jumps you straight to it. Can't recall which book? Search your whole library at once. LISTEN INSTEAD Have any book read aloud, or bring your own audiobooks in. Real chapters, sleep timer, lock screen controls. Own both formats? Switch between reading and listening and pick up in the same spot. KEEP EVERY LINE YOU LOVED Highlight it, note it, tag it, and actually keep it. Your Notebook searches every highlight and note across your whole library at once. Export to Markdown or Readwise, or turn a line into a quote card worth sharing. Switching from another reader? Bring your highlights with you. EVERY WORD, EVERY NAME Hard words get a plain-English hint right above them, no flow broken. Look one up enough times and it lands in your vocabulary deck for review. Offline dictionary and translation are built in. Too many invented names to track? Write your own glossary entry once and RookReader reminds you every time it reappears. ONE ACCOUNT. EVERY DEVICE. iPhone, iPad, and every other device you read on all pull from the same shelf. Your library, collections and reading stats follow you everywhere, free — and so does your place in one book, so you can watch sync work before you pay for it. Go Pro and your exact page, every highlight and every note sync too, on every book, quietly in the background. KOReader users can sync positions as well. A READING HABIT YOU CAN SEE Streaks, minutes, books finished, and a year in reading worth showing off. Commit to a finish-by date and get tonight's page count. Close the last page of a book and the next one in the series is already waiting. OWN IT. DON'T RENT IT. Pay once. That's it, forever. No subscription creeping onto your card.
