Help me create prompts

A free prompt builder. Everything runs in your browser; nothing you type is sent to us.

Good prompts aren't about magic words. They're about giving the AI the information a smart new colleague would need. This builder walks you through the five parts that make the difference: role, task, context, format, and constraints. Fill in what you can, press Build prompt, then copy the result into Grok or any other AI assistant.

How to fill in each field

1. Role

The role sets the expertise and perspective the AI should write from. "You are a copywriter" is fine; "You are a conversion copywriter who writes for local service businesses" is better, because it implies a style (direct, benefit-led) and an audience (busy homeowners). Don't overthink it. A role is a shortcut for a bundle of assumptions you'd otherwise have to spell out.

2. Task

Name the deliverable and the quantity. "Help with my newsletter" is a topic; "Write a 300-word newsletter announcing our new opening hours" is a task. If you want options, say how many. If the job is big, split it: ask for an outline first, then each section.

3. Context

This is where your results are won or lost. The model knows a lot about the world and nothing about you. Include who the audience is, what you're selling or explaining, what the reader should do next, what you've tried, and real details (location, prices you've confirmed, product names). Pasting a short sample of your own writing is the fastest way to get output in your voice. Leave out passwords and private customer data.

4. Format

Tell the AI the shape of the answer: a table, a numbered list, Markdown with headings, a code file, a set of subject lines with character counts. Length limits belong here too. Clear formats make output easier to review and paste where it needs to go.

5. Constraints

Constraints prevent the failures you already know about. Common ones: "Don't invent statistics or testimonials." "Avoid the words 'unlock' and 'seamless'." "Eighth-grade reading level." "Stay under 60 characters." The "don't invent facts" checkbox adds a line telling the model to mark missing information instead of making it up, which is one of the most useful constraints you can use.

Example prompts built with this tool

Website homepage

You are a UX writer for small-business websites.
Task: Write the homepage hero section and three benefit sections for a dog-grooming salon.
Context: We're in Austin, TX. We specialize in anxious dogs and offer quiet, one-dog-at-a-time appointments. Most customers book on their phone.
Format: Markdown with H2 headings; hero = headline, subheadline, button text.
Constraints: No invented reviews or numbers. Friendly but not cutesy.

Google search ad

You are a search-ads specialist.
Task: Write 8 headlines and 4 descriptions for a Google search ad for emergency boiler repair.
Context: Serving Leeds, UK. Engineers are Gas Safe registered. Customers search when their heating fails.
Format: Two lists with character counts in brackets.
Constraints: Check each against the current Google Ads limits I give you: [limits]. No prices.

Automation

You are an operations consultant.
Task: Turn my weekly reporting routine into a step-by-step SOP and flag what could be automated.
Context: Every Monday I export sales from Shopify, paste into Google Sheets, make a chart, and email it to two partners.
Format: Table with Step | Time | Automatable? | How.
Constraints: Prefer tools I already use. Ask before assuming any paid software.

Why structured prompts work

An AI model fills in anything you don't specify with the most typical choice. Sometimes typical is fine. For anything you'll publish, sell with, or act on, typical is the enemy: typical audience, typical tone, typical claims. Each field above removes a category of guesswork. You'll still need to review and refine; the best first drafts come from prompts like these, and the best final drafts come from specific follow-ups like "make the second section half as long and use the phrase our customers use: 'finally, a calm groom.'"

Frequently asked questions

Does this work with tools other than Grok?

Yes. The five-part structure is tool-agnostic. It works in any capable chat assistant, and the same fields make a good brief for AI agents that take actions for you.

Do I need to fill in every field?

No. For a quick question, a task alone is fine. Add fields as the stakes rise: anything you'll publish, send to customers, or spend money on deserves all five.

Is what I type stored anywhere?

No. The builder is a few lines of JavaScript that run in your browser. Nothing is sent to eTarget. Once you paste the prompt into an AI tool, that provider's privacy policy applies, so leave out sensitive data.

The answer still isn't right. What now?

Don't start over. Reply in the same chat with one specific change at a time: "shorter," "more concrete examples," "use British spelling," "remove the second section." If the conversation has drifted badly, start a new chat with an improved prompt that includes what you learned.
