Origin Reader: English Books

Read the original. Keep your own understanding. Origin Reader brings English EPUB reading, focused AI help and a personal notebook together for independent readers age 13 and up, on iPhone and iPad. ASK WHILE YOU READ Ask about a word, sentence or reading context, then follow up in the same conversation. Copy or share an answer, give feedback, request a new answer, or use it as the starting point for your own note. BUILD A NOTEBOOK OF YOUR OWN Write a quick thought or keep the passage and AI answer beside your own interpretation. Organize notes into collections, add tags, pin important ideas and choose a note color. Use Markdown writing tools, preview and checklists, then search your notes or export them as Markdown. MAKE ROOM FOR READING Import DRM-free EPUBs you lawfully own or are authorized to use. Browse your library with covers, search, book tags and adjustable layouts. Open the contents, turn pages or scroll, and return to your saved reading position. Choose text size, line spacing, margins and page colors. Download selected open-source reading fonts to use in Display Settings. Set the app to light, dark or system appearance. English and Simplified Chinese interfaces and AI explanations follow your app language; English book text stays in its original language. ONE PURCHASE, ROOM TO READ AND WRITE Your one-time App Store purchase includes local reading, the notebook and a one-time allowance of 20 successful online AI responses. A successfully regenerated answer uses one response. Restore Purchase retrieves the remaining allowance for the same verified purchaser. Local reading and notes work offline and remain available after the allowance is used. Online AI requires a connection, available allowance and your data-sharing consent. It processes limited reading context through Alibaba Cloud Model Studio Qwen in Beijing. EPUB files and notes are stored privately on your device, with sharing and export under your control. Downloaded fonts also work offline.
