Most AI tools pull their punches on dark fiction
Ask a general-purpose assistant for a genuinely frightening scene, or an explicit one, and you'll often get a disclaimer or a quietly softened version. Fictensity just writes the scene. Graphic violence and explicit sex between adult characters are fine here, and what your story does with them is up to you.
There are hard limits, though: nothing sexual involving anyone under 18 or real people, and no real-world instructions for hurting someone.
Or play it as a story
Storyplay turns a session into interactive fiction. You say what your character does and the story reacts. Your choices stick.
Private by default
Your stories belong to your account and aren't public. We never put your writing in emails, and you can delete a session whenever you want.
Same scene, sharper
She was scared as she walked down the dark hallway. She heard a noise behind her and started to run.
The hallway lights ran on motion sensors, and they were going out behind her, one by one. She hadn’t passed the last three.
