NarraLume is a writing studio for long novels where the AI proposes and you dispose, so a book stays yours across tens of thousands of words. Everything lives around the story bible: your stated intent, outline, entities, confirmed facts, relationships, chronology, and foreshadowing, kept as the single source of truth that planning, drafting, and review all read from. You can write chapters by hand in the studio, save versions and comments, ask for a selection edit, or delegate a chapter, a run of chapters, or a whole quick-creation plan to a model; whatever comes back arrives as a candidate with diffs, never as silent edits to your manuscript or canon. Review findings come with evidence you can accept, reject, or mark as false positives, and when generated prose collides with a locked fact the task stops and waits for your ruling instead of improvising around it. The run center keeps every AI job's steps, model calls, and checkpoints recoverable, the long-form lab searches story memory and previews plot impact without touching the book, and delivery ends with quality checks, exports, snapshots, and full-library backups.
