How it works
- Describe the task in a sentence or two, the way you'd brief a colleague: what you want done, for whom, and what you'll paste in.
- Pick the AI you use and how detailed the prompt should be, add any context, and click Write my prompt.
- Copy the prompt into ChatGPT, Claude or Gemini, replace the [PLACEHOLDERS] with your material, and run it. The notes underneath explain each placeholder.

Tips for better results
- Say who the result is for and what they care about. "For my VP, who reads on her phone and cares about risks" changes the prompt far more than "make it professional".
- Mention what you'll paste in: notes, a contract, a spreadsheet, survey answers. The generator builds the prompt around your material and tells the AI to stick to it.
- Use Detailed for work you'll repeat or can't afford to get wrong. You get an output template and stricter checks you can reuse every week.
- If the first answer from ChatGPT or Claude misses, don't start over. Tell it which rule in the prompt it broke, or add the missing detail to the prompt and run it again.
FAQ
Is this AI prompt generator free?
Yes. Enter your email once to start using it (you'll also get Something Big, our free weekly AI newsletter, and you can unsubscribe anytime). No account or credit card.
Does it work for ChatGPT, Claude and Gemini?
Yes. Pick your AI and the prompt is shaped for it (for example, XML tags for long documents in Claude, and file uploads for counting in ChatGPT). Choose Any AI for a prompt that works in all three.
What makes a prompt good?
A clear job and goal, the material the AI should use, the steps an expert would take, an exact output format, and a check for the likely mistakes. Every prompt this tool writes has those parts, plus rules against making up facts.
Can it improve a prompt I already have?
Yes. Paste your prompt into the task box. It rewrites it for the same job, keeps what already works, and explains what it changed.
