Leeef Reader

Leeef Reader is an offline-first, cross-platform ebook reader that keeps you in control of your data. Import and organize books without an account, then connect your own S3 or WebDAV storage when you want continuity across devices. MULTI-FORMAT LIBRARY Read EPUB, PDF, TXT, MOBI, AZW3, and FB2. Import from Files or the system share sheet, extract covers and metadata, and organize everything with shelves, tags, filters, and sorting. FOCUSED READING Enjoy interactive page curl on mobile, or choose slide, no animation, and continuous scrolling. Tune typography, spacing, margins, themes, dark mode, and Chinese text conversion. HIGHLIGHTS, NOTES, AND INSIGHTS Create bookmarks, highlights, and notes, review them by book or date, and export to Markdown, TXT, or CSV. Reading statistics help you understand time, streaks, and completion. AI AND CLOUD STORAGE CONFIGURED ON DESKTOP, SYNCED TO IPHONE Connect your own object storage and AI service on a computer for cross-device sync, explanations, translation, chapter summaries, and reading questions. The iPhone app does not include object-storage, AI, or cloud TTS endpoint, key, or provider entry; credentials reach iOS after you scan a pairing QR code or through trusted-device / cloud sync. YOUR CLOUD, YOUR DATA Leeef stores data locally by default and requires no account. Optional S3 or WebDAV sync keeps books, progress, highlights, and shelves in step across your devices. Some online features require a network connection. S3/WebDAV uses storage you provide. Storage and AI credentials are configured on desktop and synced; they are not purchased or entered in the iOS app.\n
