Short story prompt

A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional short story on the first try, plus the cheapest model that does it well.

What most people type

write a short story about a lighthouse keeper who finds a message in a bottle

It works, but the AI has to guess your tone or genre, e.g. mystery, melancholy, hopeful, setting and time period and message content or sender, or let the story decide, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.

The better prompt

Write a short story about a lighthouse keeper who finds a message in a bottle.

Details to use:
- Tone/genre: [tone or genre, e.g. mystery, melancholy, hopeful]
- Setting and era: [setting and time period]
- What the message says or who it is from: [message content or sender, or let the story decide]
- Point of view: [first or third person]

Give the story a clear arc: an opening that establishes the keeper and their routine, the discovery of the bottle, a turning point driven by the message, and a resolution that lands emotionally. Make the keeper a specific character with a distinct voice and a small personal stake in the message, and use concrete sensory detail rather than generic sea imagery.

Length: about [word count, e.g. 800-1,200 words]. Give the story a title. Return only the story, with no commentary.

Replace the [brackets] with your details before you send it: tone or genre, e.g. mystery, melancholy, hopeful, setting and time period, message content or sender, or let the story decide, first or third person, word count, e.g. 800-1,200 words.
