01BUILD
One line in.
A whole world out.
Start with a place, a person and something at stake: a haunted lighthouse, a megacity heist, a quiet village shop. Creation OS builds the world around it, with a named cast who want things, places worth visiting, factions with history, and a character for you, ready on the first turn.
- Any genre, from noir to a fourth-tier football club
- A full cast, linked to places, powers and each other
- Your first built world is free
“A haunted lighthouse on a crumbling cliff where the last keeper guards a dying signal.”
02PLAY
Write what you do.
The world answers.
No menu of three choices. Talk your way past a quartermaster, unfold a turret on the deck, or take the job nobody wants. The Narrator writes the scene around your action, people answer in their own voices, and your character, kit and abilities sit beside the story where you can use them.

03THE RECORD
The world keeps track.
People remember how you treated them. Coin, kit and wounds carry from turn to turn. The Journal holds everyone you have met, every place you have found and every objective in play, so you can check the record instead of guessing.
turns reached by one public world, sealed with its record. Inspect the record ▶

04THE SHOWCASE
Or start in a world
someone else built.
Over 60 published worlds, from a monastery scriptorium to a magic academy. Open one, read its premise and a sample turn, and play your own copy. Starting a Showcase world is free; you only spend Spark on turns.

COMPARE
How Creation OS compares with other AI RPGs
Each comparison is written by Creation OS, dated, and sticks to documented features.
What is Creation OS?
Creation OS is an AI roleplaying game you play in your browser. You describe a world or pick a published one, then write what your character does. The Narrator answers, and the world keeps track of its people, places, possessions and relationships as you play.
Is Creation OS free?
Yes, to start. Every account gets 150 Spark (up to 50 turns), its first built world free and one Art Forge picture, with no card required. Pro is US$14.99 a month and adds 1,500 Spark each billing cycle, unlimited built worlds, Tome binding and more.
Does it remember my story?
Creation OS keeps a record of the people you meet, the places you find, what you carry, your money and how people feel about you, and you can check it in the Journal at any time. One public world reached turn 5,011 and its record can be inspected. The Narrator can still slip, and you can ask it out of character to correct a detail.
Can I play with friends?
Yes. A Shared World holds up to six players. Each plays their own character, takes turns on their own schedule and pays for their own turns.
What genres can I play?
Any you can describe: fantasy, science fiction, horror, noir, historical, modern, survival, a cosy shop, a monastery or a football club. The Showcase has over 60 published worlds to start from.
Can I make pictures of my characters?
Yes. Art Forge paints characters, items, places, factions, scenes and book covers in your world's style. Every account starts with one free picture, Pro includes ten each billing cycle, and Pro players can upload their own character portrait.
Does Creation OS work on my phone?
Yes. It runs in your phone's browser with a layout built for small screens, and the same world continues on any device you sign in on.
How is Creation OS different from AI Dungeon or Voyage?
Creation OS builds each world with a full cast, places, factions and history before you start, keeps a record you can check in the Journal, and offers Shared Worlds, Tome books and LAWGRAVE, a hand-built universe. Our comparison pages cover Voyage, AI Dungeon, Friends & Fables and others feature by feature.
SYS.READY
