Book ideas rarely arrive while you are at your desk. Jiraiya for iPhone is the notebook for catching them on the spot. Your notes sync through iCloud to your Mac with the same Apple Account, and the Jiraiya Mac app brings them into your manuscript. You write the book on Mac; iPhone is where you gather the material. CAPTURE ON THE SPOT • Capture ideas with text, photos, or voice • Add notes quickly from widgets, Siri, Shortcuts, or the Action Button • Keep the capture time and, when permitted, location • On supported devices, Sennin Mode suggests tags and writing prompts on device (requires an Apple Intelligence capable device) REREAD THE BOOK YOU WRITE ON MAC Browse books created on Mac and synced through iCloud, organized by act, chapter, and section. When rereading sparks a thought, save it as a new Field Note. DASHBOARD View the days, time, and characters you wrote on Mac, plus your KDP sales summaries, in Dashboard. Switch between Writing and Sales performance. In Writing, choose a book and a period (7 days, 30 days, 3 months, or 1 year). Records and summaries are created on Mac and arrive through iCloud; iPhone is view-only. Only time and character counts are recorded, never the text itself. KDP sales appear only after you explicitly enable sales summary sync on Mac. Original Excel files, ASINs, KDP Dashboard estimates, and Payment Reports are not uploaded to iCloud. JIRAIYA PRO Your subscription is shared with the Mac app. On Mac, unlimited books, EPUB Reader preview, PDF export, Focus Mode, EPUB export, and M4B export are Pro features. The free Mac version includes one book. Manuscript writing and file export also take place on Mac. iCloud sync requires the same Apple Account on each device. Jiraiya Pro is an auto-renewing monthly or annual subscription. The price appears on the App Store purchase screen.
