AI Writing Prompt Generator

An AI writing prompt generator for writers, classes and AI tools

This AI writing prompt generator does two jobs. For people, it deals out creative writing prompts — a character, a setting, what they want, a problem, a twist, a constraint and, if you like, a first line — for short stories, flash fiction, poems, journal entries, letters, dialogue scenes and opinion essays, pitched at kids, teens or adults and at three levels of difficulty.

For AI tools, it writes a detailed prompt that tells ChatGPT, Claude, Gemini or any assistant exactly what to write: the type of piece, topic, audience, reading level, structure, point of view, tense, word count, tone, a sample of your own voice and a list of banned clichés.

Every creative prompt comes from a seed. Tick Prompt of the day and the date is the seed, so a whole class — or a writing group — gets the same prompt today. Type your own seed to reproduce a set later, and download 10, 20 or 30 prompts as a printable classroom PDF.

How to get a writing prompt

1. Choose Writing prompts for people or A prompt for an AI to write — or start from an example.
2. For people: pick the audience, type of writing, genre and difficulty, and how many prompts you want.
3. Keep Prompt of the day ticked for today’s shared prompt, or press New prompts for a fresh seed.
4. For a class, choose a pack size and press Download classroom pack (PDF).
5. For an AI: fill in the type, topic, audience, reading level, word count and structure, add a voice sample and banned words, then copy the prompt.

What the difficulty levels add

Lengths follow the audience: about 300 words for a kids’ story, 800 for teens and 1,500 for adults; flash fiction stays under 200, 500 or 750 words. Essay prompts ask for two reasons (easy), three reasons and a counter-argument (medium), or both sides with named evidence (challenge).

Worked examples

Three story starters for a class of children — seed “class-3a”, easy, with first lines:

1. Write a short story (about 300 words) about a pirate who gets seasick and is searching for a lost pet. It takes place at a desert research camp. Begin with this line: “Every map in the library had my house on it — except the newest one.”

2. Write a short story (about 300 words) about a ferry captain on her last crossing who must find a missing key before sunset. It takes place on a lighthouse island during a storm. Begin with this line: “I had been invisible for three days before anyone noticed.”

3. Write a short story (about 300 words) about a twin who swaps places with her sister for a day and wants to prove everyone wrong. It takes place in a museum after closing time. Begin with this line: “We buried the time capsule on Friday; on Monday it was back.”

And the “Blog post” example for an AI, built with the same engine as the AI prompt generator:

You are an experienced blog writer.

Task:
Write a blog post about how to start composting in a small flat.

Audience:
beginners who live in flats with no garden

Steps:
1. Open with a hook that names the reader’s problem
2. Cover the topic in three to five sections with clear headings
3. Close with one specific call to action

Rules:
- Write for general adult readers: plain English, no jargon.
- Do not use these words or phrases: delve, game-changer, in today’s fast-paced world.

Output format:
Format the response in Markdown, with headings and lists where they help.
Tone: friendly.
Length: about 900 words.

Tips for teachers and writing groups

• Share the seed, not just the prompt: anyone who enters it with the same options gets the same set.
• Use Challenge prompts sparingly with younger writers — one constraint at a time is plenty.
• Ask writers to check their length with the word counter and their sentences with the readability checker.
• When a student uses an AI tool, ask them to write the prompt themselves — choosing structure, audience and tone is part of the skill.
