Who it’s for

Fitness coaches, nutrition pros and app builders.

Adapt it to your industry

  • Fitness coach: weekly plans and check-ins for clients
  • Clinic: draft patient reminders and plain-language handouts
  • Caregiver: keep a clear log of medications 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.

How to make money from it

Pricing idea: Coaches can sell monthly plans with AI-assisted check-ins; apps usually sell a monthly or yearly subscription.

Finding your first 10 customers

  • Start with clients or friends you already help.
  • Share honest progress stories (with permission).
  • Partner with a local gym, clinic or practitioner.
