Always read what the AI writes before you send it to a customer. Check prices, dates and anything legal.

Why a good prompt matters

ChatGPT and Claude write much better when they know who you are, who the message is for and what a good answer looks like. A vague request gets a vague, robotic answer. Each prompt this builder makes includes the four things AI tools need:

  • Role: who the AI should act as, for example an office manager at a roofing company.
  • Context: your trade, your business and the details of the job.
  • Task: exactly what to write or build.
  • Rules and format: length, tone, what to avoid and how to lay out the answer.

Simple automations you can build with a $20 AI plan

You don't need a developer or expensive software for the basics. With a Google account and a ChatGPT or Claude plan, you can set up:

  • An estimate tracker in Google Sheets with the date sent, the amount and the next follow-up date.
  • A daily email that lists the estimates you need to follow up on today, using a short Google Sheets script the AI writes for you.
  • Gmail templates and filters so the same customer questions take seconds to answer.

Pick one of the "Simple automations" tasks above and the prompt walks the AI through it step by step, in plain English.

Example prompt: job notes to estimate

You are the office manager of a small roofing company. Turn my job notes into a clear estimate description a homeowner can understand... (choose the task above to see the full prompt)

Frequently asked questions

Do these prompts work with the free version of ChatGPT?

Yes. The writing prompts work on free plans. The automation prompts also work, though a paid plan handles longer scripts and step-by-step help more smoothly.

Should I use ChatGPT or Claude?

Both work well for this. Use the one you already pay for. The prompts are written to work in either, and in Gemini too.

Is it safe to paste customer information into ChatGPT?

Keep it to what the task needs, like a first name and the job details. Never paste card numbers, passwords or anything you would not put in an email. Check your AI tool's privacy settings.

Can AI write my estimates for me?

It can turn your notes into a clean, professional description. You still set the price and check every line before you send it.

Is this prompt builder free?

Yes. No signup, no email, no limit.
