Prompt Generator For Marketers – PromptByJob

Marketing AI Prompt Builder for ChatGPT, Claude, Gemini and similar assistants

Pick a marketing task, add your real offer and audience details, and get one structured prompt to paste into the AI assistant you already use.

What this tool does

This is a browser-based prompt builder. It assembles your answers into a structured prompt using fixed templates. It does not call an AI service or write the marketing content itself — you copy the prompt and paste it into an AI assistant of your choice. Each task type produces a different deliverable, and your inputs change the instructions (for example, the number of emails, the length of the calendar, or the data to analyse).

Privacy: Do not enter customer personal data, client confidential details, unreleased financials, passwords or API keys. Describe your business in general terms where possible.
Be specific, e.g. “freelance designers who invoice manually and dislike spreadsheets”.
E.g. “£2,000 total, one person, no designer”.
Product or service, price, differentiators, and any claims you can substantiate. The AI is told to use only these facts and not invent others. Do not paste customer personal data or confidential client information.
E.g. word limits, banned phrases, legal or brand rules, deadline, small team.

Worked example (illustrative)

This example uses a fictional brand and demonstrates how the prompt is constructed. It is not a real campaign, and no AI response or result is shown or implied.

1. Example inputs


  
2. Prompt generated from those inputs

  

  
3. How the inputs shaped the prompt

  
    
    
  • The task Email sequence plus “4 emails” produced a per-email deliverable list (subject line, preview text, body, one call to action, send timing) instead of a general strategy outline.
    • 
    
  • The offer facts and the constraints (“no discount above 10%”, “no health claims”) appear as hard limits, and the AI is told not to invent other facts.
    • 
    
  • The audience, funnel stage and goal set the purpose of the sequence (win-back), and the tone sets the writing style.

How it works

  
    
    
  1. Choose the task. Fields that only matter for that task (email count, calendar length, performance data) appear automatically.
    2. 
    
  2. Enter your audience, goal and verified offer facts. Optional fields are left out of the prompt if blank.
    3. 
    
  3. The page builds one prompt in your browser from fixed templates. Every prompt asks the AI to separate your supplied facts from its assumptions and to avoid inventing statistics, testimonials or competitor claims.
    4. 
    
  4. Copy the prompt into an AI assistant and refine the conversation from there.
    5. 
  

  
Limitations and privacy

  
    
    
  • Prompts are starting points. AI responses can contain errors, outdated platform rules or unsuitable claims; check facts, platform policies, advertising rules and email-marketing law before publishing or sending anything.
    • 
    
  • The prompt is built by this page’s JavaScript on your device. This page does not send your form entries anywhere, but this describes only this tool’s code — your wider site (analytics, consent tools) and the AI service you paste into have their own data handling.
    • 
    
  • Templates have not been tested against every possible input combination, and the tool does not fact-check or guarantee any outcome.
    • 
  






  
Frequently asked questions

  
Does this tool write the marketing copy?
No. It only builds the prompt. The copy comes from whichever AI assistant you paste the prompt into.

  
How is this different from typing a request into an AI assistant?
It saves you from forgetting the details that shape a good brief — audience, goal, constraints, deliverable format — and always includes instructions to avoid invented facts. You can reach similar prompts by writing them yourself.

  
What should I put in the offer field?
Only facts you can stand behind: what you sell, price or terms, genuine differentiators, and approved claims. Anything you leave out, the AI is told to treat as unknown rather than make up.

  
Can I use it for a client’s brand?
Yes, using general descriptions. Avoid confidential contracts, pricing or unreleased plans, and check any client or agency rules on AI tools.

  
Why does the same prompt give different answers each time?
AI assistants generate text probabilistically, so some variation is normal. Specific audience details and constraints usually narrow the range.
