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. Write down one problem a specific group of people pays to solve (for example “gym owners losing members”).
  2. Open ChatGPT, Claude or Grok and paste the prompt below to sharpen the idea and list what the first version must do.
  3. Use ChatGPT, Claude or Grok to make the first version of the product for one type of customer.
  4. Create a Stripe account and a Payment Link so people can pay from day one.
  5. Make a one-page website that explains the problem, the fix and the price.
  6. Show it to 10 people from your target group and change what confuses them.
  7. Launch where those people already gather, then ask every new user for feedback.
