Live the story as your own.

momosama is an AI text role-playing game. Step into a fictional world and decide what happens next — through the story, its people and an in-world phone.

Effective September 23, 2026

Every start is its own world

A script sets up the beginning; your world records everything after. People, the map, stats, resources and objectives make up its current state. One script can have several separate runs, and characters with the same name never share chats across them.

Scripts and visual themes

Rain on Willow Lane is a script about running an old bookshop and getting to know its neighbors. The Floating Atlas and Letters at Dusk are visual themes for a world’s cover and atmosphere. They are not separately published scripts and do not prescribe a plot. Check the signed-in world library for available scripts.

A phone inside the story

Install contacts, journal and character tools from the App Store. Installs follow your account; chats and app content belong to the current world. You can pick parts of a conversation to bring into the main story; journals, vignettes and character drafts only take effect after you confirm.

Keep playing, or keep a page

Completed story turns and app actions save to the cloud. A save freezes one moment; loading it restores the story, people and phone together.

You can export a save for another player. Once imported, they have their own separate world; later changes on either side don’t affect the other. Account identity, credits and payment records are never copied with a save.
