Whether you read for curiosity, study, travel, or a few quiet minutes each day, Pacibook keeps discovery and reading together in one clean experience. Browse the catalogue before creating an account, open clear title details, and choose what you want to read without fighting a cluttered interface. DISCOVER YOUR NEXT READ • Browse a growing catalogue from Pacibook publishers and authors. • Search by title or author when you already know what you want. • Explore category filters when you want inspiration. • See recommendations that help you return to interesting literature. • Review useful title details before opening the reader. A READER BUILT FOR FOCUS Pacibook gives the page the attention it deserves. Turn pages naturally, zoom when text needs a closer look, and keep your place as you move through a publication. Light and dark themes help the interface fit your surroundings, while a simple navigation system keeps the catalogue, search, library, and account close at hand. READ OFFLINE Download eligible ebooks to your device and keep reading when your connection is unreliable or unavailable. Offline access is useful on commutes, flights, and anywhere a steady signal cannot be guaranteed. Downloaded content is protected on the device and stays available from your library while your access permits it. HIGHLIGHT IMPORTANT PASSAGES Mark useful sections directly on a page and return to a text with your private highlights intact. Highlights are stored locally so they remain useful during offline reading too. BUILD A CONSISTENT READING HABIT • Track reading time through a daily reading streak. • See current and longest streak information. • Choose a daily reminder at a time that suits you. • Share a streak card when you want to celebrate progress. Reminders are optional. Pacibook asks for notification permission only when you decide to enable them, never simply because the app was opened. OPTIONAL AI READING TOOLS Eligible access passes can include AI tools inside the reader. Translate selectable page text into supported languages, ask a question about the nearby reading context, or create a summary of the pages you are studying. Availability depends on the selected pass, the content, and connectivity. YOUR LIBRARY AND ACCOUNT Sign in to keep access tied to your account, manage purchases, view orders, check your coin balance, and download titles for offline use. Pacibook supports email sign-in and platform sign-in options where available. You can also raise a support request, review privacy and terms, sign out, or permanently delete your account from inside the app. FLEXIBLE ACCESS Read free content where offered, access individual titles with coins, or choose a fixed-duration catalogue pass. Store purchases are one-time purchases for the stated access period, not automatically renewing subscriptions. Payments in the iOS version are processed securely by the App Store. PRIVACY-CONSCIOUS BY DESIGN Pacibook does not request location, contacts, camera, photo-library, or tracking permission. Account and purchase data are sent over HTTPS. The app includes clear privacy information, in-app support, and account deletion controls. START SIMPLY A short, skippable walkthrough introduces the essentials on first launch. Then browse the catalogue, choose a title, and make reading part of your day with Pacibook.

Athene is a reader for the books you already own. Bring your books from Files, from Mail, from your computer over Wi‑Fi, from a link, or from anywhere that can share a file, and they go on a shelf that looks like one. EPUB and PDF open as they are; MOBI, AZW3, Word, FB2, TXT and HTML files become books as they arrive. Free classics from Project Gutenberg are a tap away. If you keep your library on a calibre server, Athene browses that shelf too, from + in your Library — on your home network, or from anywhere through your own VPN such as Tailscale. THE PAGE Open a book and the app steps back. Just the page, on white, sepia or night paper, or paper in any colour you like, in the typeface and size you read best, including any Google Font. Highlight a passage, add a note, drop a bookmark, and find them all again under Marks. Select a passage in another language to translate it. The shelf itself follows the time of day — Morning, Sunset, Night — or stays on the one you pick. NOTES YOU CAN DRAW Type a note in the margin, or sketch in it. On a PDF, mark up the page itself with Apple Pencil. THE NOTEBOOK Every highlight, note and drawing from every book you read, in one place, with filters and search. Write what stayed with you after a chapter, a reading session or a whole book, typed or drawn; your reflections stay even if the book leaves your shelf. LISTEN Any book, read aloud in a warm, natural voice that runs entirely on your device, and keeps reading with the screen locked. PDFs too: Listen skips the running heads, page numbers and footnotes, reads scanned pages, and describes the pictures and tables as it reaches them. The voice is a one-time download of about 242 MB. A DICTIONARY Select a word to see what it means and how to say it. It is built in, and it works offline. ASK THE PAGE Tap the owl while you read and ask about what is in front of you. Who is she again? What did that word mean? What just happened? The Owl answers from the pages around where you are — this chapter at most, never the whole book, never your other books — and if the pages do not say, it tells you that instead of guessing. YOUR MODEL, YOUR CHOICE On a device with Apple Intelligence, the Owl thinks on the device and nothing you ask is sent anywhere. Or point it at your own Ollama server on your own network. Or bring a key from Claude, OpenRouter or OpenAI. Athene asks before the first question leaves the device, names the address it would send to, and remembers your answer. ON EVERY DEVICE Turn on iCloud Sync and your place, highlights, notes, drawings, collections and reading settings follow you between your iPhone and iPad. It goes only to your own private iCloud, and what you wrote is encrypted on your device first. With a calibre server, highlights go both ways: yours to your calibre library, and the ones you make in calibre's own reader to Athene. With KOReader on an e-reader, your books, your place, and your highlights, notes and bookmarks stay in step through a sync server of your own. PRIVATE BY CONSTRUCTION Athene has no account, no analytics and no servers of its own. Your books, your notes and your questions stay on your device or go only where you have pointed them. The privacy policy says the same, in plain words. FREE Reading is free. No account, no subscription, no limit: the shelf, the reader, Listen, the dictionary, the Owl, the Notebook, iCloud Sync, calibre and KOReader, your highlights and notes. Nothing is locked. WHAT READERS SAY “The app works perfectly with my Calibre library.” (ZenoNow) “It was very simple to connect to my existing calibre website.” (linux0117) “I’d happily pay for Athene if it weren’t free.” (Momji_iphone) Athene requires iOS 26. The on-device Owl requires Apple Intelligence (iPhone 15 Pro and later, M-series iPad, iPad mini A17 Pro); on other devices the Owl works with your own Ollama server or an API key. Pictures in PDFs are described on iOS 27 with Apple Intelligence.

Verdict
The clearest difference is in-app purchases: Athene Reader at none against Pacibook's 3. Athene Reader also leads on update cadence (daily vs every 8 days). Pacibook's advantage is iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
