Stories can begin with almost anything. Strange dreams. Personal encounters. Existing influences. The problem is turning that spark into something with a beginning, middle, and end. That’s why it’s normal for most fiction writers to have a notes app with a graveyard of story ideas. Pilot chapters that trail off mid-scene. Or characters with no plot attached. That’s where AI tools for writing stories can prove useful.
A recent comprehensive survey and analysis found that 51% of fiction authors surveyed have used AI. And yes, these AI tools assist in developing ideas, building characters, shaping plots, generating scenes, and keeping a narrative moving.
With that in mind, here are five picks that help you avoid hitting a wall when writing stories.
