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.

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?
