Your prompt
You are a disgraced knight. The last free city clings to a cliff above a sea that swallowed three kingdoms. A masked noble accuses you of a murder that hasn't happened yet, and they're someone you don't trust for a second. The catch: the murdered noble has been dead a week and still gives orders. By first light, the real killer walks free and picks the next name — so choose now. Keep the mood romantic and aching.
How to use it
- Pick a genre: fantasy, sci-fi, mystery or horror.
- Read the prompt, then lock the pieces you like: the setting, the secret, the deadline.
- Ask for a new prompt: only the unlocked pieces change.
- Copy the prompt, or copy a link that opens the same prompt for your writing partner, your group or your game.
Built to be played, not read
Each prompt follows the shape a good game master uses: a setting, who you are, an inciting incident, a character in conflict with you, information you don’t have yet, and a decision you can’t put off. That is the difference between “you’re in a magical world with a prince” and a scene that pulls you in on the first line.
Example prompts by genre
Fantasy
Lantern-smoke hangs over the drowned market district. A masked noble — whom you owe a life-debt to — hires you to prove the kingdom's roads are redrawn every midnight. What you don't yet know: every corrected road leads back to a room sealed before you were born. By first light, the redrawn borders swallow the district you're standing in, and you have to decide how far you'll go.
Sci-fi
A generation ship drifts three years from a planet that stopped answering. An AI that woke up this morning hires you to prove the ship's clocks are running slow on purpose, and you were betrayed by it once already. What you don't yet know: the slow clocks hide a week the crew has lived twice. Before the storm breaks, the ship loops that lost week again, and you have to decide how far you'll go.
Mystery
Fog rolls off the harbour into a town where three people vanished on the same street. A grieving widow — whom you don't trust for a second — hires you to prove a death was an accident, then flinches when you agree. What you don't yet know: the accident was rehearsed three times before it worked. Before anyone else wakes, the third victim goes missing on that same street, and you have to decide how far you'll go.
Horror
The power dies across the whole valley the night you arrive, and only your house has light. The previous caretaker — still on shift — begs you to stay awake with them until the thing outside gives up, and you were betrayed by them once already. What you don't yet know: the thing outside wears the voice of whoever falls asleep first. Before the storm breaks, whoever sleeps first stops being the one who wakes, and you have to decide how far you'll go.
Questions
- What makes a good roleplay prompt?
- A playable prompt gives you a situation that is already changing (a role, a hook, a secret and a deadline) so you can respond instead of staring at a blank page. Every prompt here is built from those beats, not from a pile of adjectives.
- Do I need an account?
- No. The generator runs in your browser, with no sign-up and no AI.
- Can I keep the parts I like?
- Yes. Lock any piece (the setting, the hidden information, the time pressure) and ask for a new prompt: the rest of the scene is rebuilt around it.
- Where can I use the prompts?
- Anywhere: a writing session, a tabletop game or a roleplay with friends. Copy the prompt, or share it straight from your phone.
