What MuiStory is
MuiStory is a free online interactive fiction platform for both readers and creators. Readers can discover and play branching stories in the browser, while creators can turn an idea, outline, or existing draft into a playable story without building a game engine from scratch.
Create stories with structure
The editor uses a Markdown-like writing workflow and supports scenes, choices, variables, conditions, images, audio, video, and interactive mini-games. This makes it possible to write a simple choose-your-own-adventure story or a more involved narrative with persistent state, character relationships, inventory, and multiple endings. An AI writing assistant can help polish passages, check consistency, and develop story ideas while the creator remains in control of the final text and choices.
Publish and share
A finished story can be published as a responsive web experience that works on desktop and mobile browsers. Readers can start playing immediately, and the platform keeps the reading experience focused on the story rather than on a complicated game launcher. The core creation experience is free, with daily AI usage included and additional options available for creators who need more capacity or want to use their own AI API key.
MuiStory is useful for fiction writers, game designers, educators, and readers who want narratives where their decisions genuinely change what happens next.
