You're on chapter 600. A name appears you half-remember. The wiki would spoil everything. StoryCodex is a smart novel reader that builds a live encyclopedia and visual Story Map of your story as you read. It tracks your progress and only remembers the events you have already reached. Stop choosing between losing track of the plot and getting spoiled by fandom wikis. LISTEN OR READ ANYWHERE Experience a polished core reading environment. Listen to your chapters aloud with high-fidelity neural voices including Supertonic, Kokoro, and Piper. Background playback, lock screen controls, and customizable reading views. No internet connection required. TAP ANY NAME, SEE WHO THEY ARE Tap a character name while reading to instantly view their profile: role, traits, power tier, and key relationships. Pulled strictly from chapters you have already read. Zero spoilers. No wiki rabbit holes. EXPLORE THE STORY MAP See characters, factions, places, and relationships as an interactive visual map. Follow alliances, rivalries, mentors, clans, sects, and shifting connections without exposing future events. The Story Map grows with your reading progress, so it stays useful and spoiler-free. YOUR STORY CODEX As you read, the local AI silently builds and updates your universe. Character profiles track names, aliases, motivations, and power progression. World building maps places, factions, cultivation systems, and items. Arc summaries break the full story into arcs, always spoiler-free. Chapter summaries log every chapter so nothing slips through. The codex carries across volumes, so your encyclopedia grows with the series. PICK UP EXACTLY WHERE YOU LEFT OFF Tap Previously before any chapter for an instant recap: the last few key events and a summary of recent chapters. Like a previously on for your novel. No reread, no spoilers, just back in the story in seconds. LOAD EPUBS OR WEB CHAPTERS Import web novels and light novels via EPUB, PDF, or plain text. Reading a multi-volume series? Save each EPUB as a volume under one series and share the same codex across all books. Paste a chapter URL from any public novel site to start reading and listening instantly. The built-in reader strips ads and clutter for a distraction-free experience. CONVERT WEB NOVELS TO EPUB Turn a saved web novel into a real EPUB for offline reading. Split long novels into volumes, each with its own table of contents, or keep one flat book. Missing chapters are downloaded first, then the finished EPUB lands in your library and is included in library exports and backups, so other reader apps can open it too. 100% ON-DEVICE. COMPLETELY PRIVATE. Your library and chapters never leave your phone. Local AI handles all analysis. No account, no external servers, no subscription required for core features.

Built for web novels, light novels, xianxia, LitRPG, and massive fantasy epics. Requires 6GB RAM or more for local AI models. Pro users on cloud AI have no device requirements. PERFECT FOR: • LitRPG, progression fantasy, cultivation/xianxia, isekai • Epic fantasy with huge casts (noble houses, guilds, sects) • Multi-volume series you read over months or years • Readers who take breaks and need quick recaps
