You write the story
Quibu retrieves, structures, and questions your material. It does not draft your manuscript or imitate your voice.
Write Fantasy.
Stay Canon.
A private, offline worldbuilding editor that remembers your lore, catches contradictions, and handles the tedious organizing. AI helps with continuity—not with writing your story.
Private and local by default

Never drafts your story

A Second Brain, Not a Ghostwriter
AI That Protects Your Canon
Quibu uses AI like a tireless continuity editor, not a co-author. Ask questions about your world, flag possible contradictions, turn text you already wrote into structured lore entries, or create optional concept art. You stay in control, and your writing is never used for training.
Find possible contradictions; you decide what is canon
Turn your own text into structured lore entries

Built for writers, not to replace them
Your Imagination Does the Creating
Quibu is designed around a hard line: AI may retrieve, organize, and question what you've made, but it does not draft your manuscript or decide your canon.
You decide what is canon
Review extracted fields, proposed lore, and possible conflicts before they become part of your world.
Useful without AI
The local worldbuilding editor works offline with no account. Add cloud or AI tools only when they earn their place.
