Who it’s for

Anyone who wants help with everyday life admin: bills, bookings, forms and planning.

Adapt it to your industry

  • Freelancer: chase unpaid invoices politely
  • Small business: handle supplier disputes and refunds
  • Family: plan meals, trips and appointments

Step by step

  1. Pick one annoying task (a refund, a booking, a form, a plan).
  2. Open ChatGPT, Claude or Grok and paste the prompt below with the details (leave out passwords and card numbers).
  3. Ask it to write the message, list what to say, or fill in the form text.
  4. Read everything before sending and fix anything that isn’t true.
  5. Send it yourself, and paste the reply back if you need a next step.
  6. Save the prompt for next time.

How to make money from it

Pricing idea: If friends keep asking you for this, offer it as a done-for-you service at a fixed price per task.

Finding your first 10 customers

  • Help 3 friends for free and ask what it saved them.
  • Offer it in local community groups.
  • Ask each person for one referral.
