A long campaign gives you people to know, gear to collect, places to revisit and decisions to live with. Creation OS brings those parts of your story together in the OmniCodex, available while you play.
- People: revisit characters and inspect your recorded relationships.
- Possessions: see your gear and the things you have acquired.
- Objectives: follow active quests and look back at completed ones.
- Places and history: return to discovered locations and read earlier events.
Write what your character says or does. The Narrator responds, and the next decision is yours. You can spend an evening following a mystery, building a business or getting to know someone who lives nearby.
Close the tab. Come back to the same story.
Completed turns save to your account. When you return, continue the same world with your character and progress ready to pick up again.
A checkpoint gives you a separate named snapshot to restore. Read the save and checkpoint guide before restoring one, because restoration replaces your current progress with that snapshot.
Start with a world you want to live in
Choose a ready-made world to begin with an established setting, or describe your own idea and follow the guided creation process. A coastal town, a detective story, a football club or a distant frontier can each become a world you return to.
Play through your browser. Art Forge can illustrate supported people and places, and Pro players can turn played history into a Tome edition.
Play solo, or bring your group
Shared Worlds lets up to six players take part with separate characters in one world. Play is asynchronous, with one turn at a time, so your friends can join the story on their own schedules.
Choose memory for the way you play
Choose Creation OS when you want a playable world with an ongoing cast, possessions, objectives and places to revisit. If your main goal is a manuscript or a conversation with one companion, our memory comparison can help you explore those different experiences.
For a long-form AI RPG, start with a world you care about. Our long-campaign guide shows how to give that story room to grow.
