Question: Is there an app that allows me to create choose-your-own-adventure style stories with branching narratives?

StoryNest.ai is an AI-powered tool to help writers craft stories. It's got a variety of tools to build stories, including interactive fiction. The tool can handle a variety of formats, including novels, scripts and educational materials, and has features like AI-assisted editing, coauthoring and story analytics.

Another good option is Talefy, which creates interactive stories in a variety of genres, including romance, action, fantasy and sci-fi. The tool lets readers make choices that steer the story, with a clean interface to navigate. Talefy also has a community through a Discord channel and new stories are added regularly.

If you want something more immersive, check out StoryScape AI. This app uses AI and the DALL-E image generation tool to create interactive stories with adjustable reading speeds, contextually generated images and multiple chapter choices. It lets you create, customize and share your own stories, with plans to add the ability to bookmark favorite stories and suggest chapter changes.
