You build the story world. Your AI stores it all in Orbismo and helps you keep it straight.

Your story world is a thousand small things: the places, the people, their history, and the customs they live by. Talk them through with ChatGPT, Claude, or the AI you already use as they come to you, and your Orbismo world becomes your story bible, ready when you sit down to write your novel, film, or game.

Get Started

How Orbismo takes your story bible further.

Every detail is a question away.

Ask about any place, person, or event while you lay out the story, and ask what makes a setting or character themselves before you return to them.

You decide what is canon.

Try out ideas with your AI for as long as you like, and it keeps what you settled apart from what is still open.

Your draft gets a continuity check.

Share a scene, and your AI can point out where it disagrees with what you settled.

You can build it with a partner.

They add to the world through their own AI, and they do not need to be a writer to bring good ideas. Shared worlds are on paid plans.

How you start.

  1. Create a world.

    Create a world and choose the Story Bible template.

  2. Connect the AI you already use.

    Connect the AI you already use, ChatGPT, Claude, or another, just once. The help site shows how.

  3. Keep talking where you already do.

    Tell your AI about a place, a person, or an event, and say whether it is settled or still open. Your AI saves it in your Orbismo world. Your draft stays wherever you write it.
