Follow, read, and revisit serialized stories in one app with Serialist. Bring novels from different websites into one library, keep your place, and make the reading experience your own. • Cross-site search and update tracking: Search supported sites by title or author, or add a novel using its book-page URL. Check new chapters, filter updated books, and pick up where you left off. • Multiple sources for one novel: Combine chapter lists from different websites. Check source status and switch while reading; if a chapter fails to load, Serialist tries available alternatives. • On-device AI chapter insights: Use Apple Intelligence for a summary of the current chapter, a recap of a selected earlier chapter, or possible future developments based on clues in a selected chapter up to your current reading position. Processing happens on your device. Predictions may differ from the original story. Requires a supported device and language, Apple Intelligence enabled, and the system model ready. • Reading your way: Adjust font, text size, line and paragraph spacing, and margins. Cycle through reading colors or customize text and background colors. Includes Traditional/Simplified Chinese conversion, left- or right-handed tap paging, immersive mode, and a searchable chapter list within the reader. • Read aloud and auto-scroll: Listen to stories or let the text scroll at your chosen speed. Optional continuous playback moves on to the next chapter automatically. • Offline reading: Download selected chapters in advance and manage offline content and storage in one place. • Reading achievements: Track completed chapters and reading streak milestones, with Game Center achievements. • Backup, restore, and iCloud: Export your library and reading progress, choose merge or replace when restoring, and sync between your own devices with iCloud. • iPhone, iPad, and iPhone Duo: Library and chapter navigation adapt to the available space, with a focused reading screen. In-app tips are an optional way to support development.
