The hardest part of writing is starting. A good prompt doesn't give you the story — it gives you the first step. From there, the story is yours. Here are prompts across every genre, designed to spark ideas and get words on the page.

Fantasy & Supernatural Prompts

You've always known your small town was strange. But you didn't know why until the night the lights in the old library turned on — and you recognized the silhouette in the window as someone who died three years ago.

You receive a text from your own number: "Don't go to school tomorrow. Trust me." The timestamp says it was sent six days in the future.

You've been hiding your magic for sixteen years. Tonight, for the first time, someone sees it — and instead of fear, they look relieved. "I've been looking for you," they say.

In your world, everyone is born with a word written on their palm. Yours says "traitor." You've spent your whole life trying to prove it wrong.

Realistic Fiction & Coming-of-Age Prompts

Your best friend of twelve years confesses something that changes everything you thought you knew about them. Now you have to decide: who do you want to be in this moment?

You found a journal in the attic with your own handwriting — but you've never written it. The last entry is dated two weeks from now.

Your summer job is helping clear out an elderly neighbor's house. In the basement, you find something that suggests they lived a completely different life than anyone knew.

Sci-Fi & Speculative Prompts

It's 2075, and you can download memories from anyone who has ever lived. For a history project, you access the memories of someone from 2024 — and they're living through something that looks exactly like your life.

In this world, you can trade years of your life for talent. Your classmate just became the best musician you've ever heard. You need to know what they gave up.

Horror & Thriller Prompts

You're the only one in your friend group who doesn't think the new kid is perfect. Maybe it's paranoia. Or maybe you're the only one who noticed they don't blink.

The abandoned house at the end of your street has been empty for twenty years. Last night, the lights came on. This morning, there's a car in the driveway — and your name on the mailbox.

Using Prompts Effectively

A prompt is a door, not a destination. Start with the situation, then ask: who is the most interesting person to put in this situation, and why? The character's unique answer to that question is where your story lives.

Don't try to write the whole story from a prompt — write the first scene, then let the next question present itself. What happens next? Who else is involved? What does your character want more than anything — and what's standing in their way?

Take your idea further with StoryDev. Start with a prompt and build it into a full story — with AI tools that help you develop characters, track your plot, and write every chapter.
