One-person AI apps earning millions a year

🧰 Before you start

• One clear problem people already pay to solve (e.g. professional headshots)
• A no-code app builder like Lovable or Replit
• A payment account (e.g. Stripe)

🪜 Steps (tick as you go)

1. ☐
   1. Pick a narrow problem

   Successful examples do one thing: headshots (HeadshotPro), AI photos (Photo AI), chat with PDFs (PDF.ai).

2. ☐
   2. Check people pay for it

   Search for existing paid services. Competition is a good sign there's demand.

3. ☐
   3. Write a one-page plan

   Use the first prompt to plan the simplest version (called an MVP, a 'minimum viable product').

4. ☐
   4. Build it without code

   Use a vibe-coding tool (you describe the app in words; the AI builds it), e.g. Lovable. See the Lovable guide on this site.

5. ☐
   5. Add payments

   Connect Stripe so customers pay before using it.

6. ☐
   6. Launch small

   Share with 20-50 people, collect feedback, fix and repeat.

7. ☐
   7. Keep it self-serve

   Write clear help pages so customers don't need to email you.

I want to build a self-serve AI product that solves [problem] for [customer type].
Give me: the simplest version I could launch in 2 weeks, 5 must-have features, 5 features to leave out for now, a suggested price, and 3 ways to find the first 50 customers without paid ads.

Build a web app called [name] where users can [main action, e.g. upload 10 selfies and receive 40 professional headshots].
Pages: landing page with price ([USD/MYR amount]), sign-up/login, upload page, results page, account page.
Take payment with Stripe before processing. Clean, modern design in [colours]. Mobile friendly.
