How to write a good AI prompt
A good prompt answers the questions the AI would otherwise have to guess. This tool asks for each part in turn:
- Task — what you want done, as a direct instruction. “Write a product description for running shoes” beats “shoes copy”.
- Role — who the AI should act as, e.g. “an experienced marketing copywriter”. It sets expertise and voice.
- Context — the background it can’t know: audience, brand voice, existing content, data.
- Format and tone — bullets, a table, numbered steps or code; professional, casual, technical or persuasive.
- Constraints — limits and must-haves: “under 150 words, no jargon, include a call to action”.
Before and after
Before: “write an email about the delay”
After: “You are a business professional. Write an email to our customers about a one-week delay in shipping their orders. Context: the delay is due to a supplier issue; orders are already paid. Respond in a short paragraph, with a friendly but concise tone. Constraints: under 120 words, apologise once, give the new delivery date.”
The second version gets a usable draft on the first try because the AI no longer has to invent the audience, the reason, the length or the tone.
How to use the prompt writer
- Start from a preset — Blog post, Email, Code review, Summarise or Social caption — or type your own task.
- Fill in whichever optional fields help: role, context, constraints.
- Pick an output format and tone.
- Copy the finished prompt and paste it into your AI assistant. Replace any [placeholders] first.
FAQ
- Is this prompt generator free?
- Yes — free with no sign-up and no limits. It builds the prompt text in your browser; you then paste it into whichever AI assistant you use.
- Why does adding a role and format improve a prompt?
- AI assistants follow structure more reliably than a vague ask. Naming a role sets the expertise and voice to draw on, and naming an output format (bullets, a table, a set number of words) stops the model from guessing at how you want the answer shaped.
- Does this send my prompt to an AI?
- No — this only builds and formats the prompt text in your browser. Copy it and paste it into ChatGPT, Claude, Gemini or any other assistant.
- Which AI should I paste the prompt into?
- Any of them — the structure works everywhere. If you're choosing a tool for an Indian business, our ChatGPT vs Gemini vs Claude guide compares them on price in rupees, GST invoices and Indian-language support.
