An interactive story world

Your story,
playable.

MomoSama is an AI text role-playing game. Step into your own world, shape the story through your actions and meet its characters — with a map, an in-world phone and saves that keep your choices together.

Not just a chat.

Choose a script, start a world and write what your character does next. AI advances the story using the script and current state, alongside relationships, places, resources and objectives. Phone chats, journals and character tools belong to that world; you choose what to bring back into the main story.

Share any moment.

Cloud saves let you return to your story. A checkpoint freezes the story, characters and phone together. Export it to a friend, and they can begin their own separate journey from that moment.

Start writing.

For players aged 18 and over. Reading and installing phone apps are free; AI generation uses credits, with the cost shown beforehand. Available scripts, sign-in options and prices are listed in the game.
