Who it’s for

People who build or maintain software, and non-developers who want a small tool made for them.

Adapt it to your industry

  • Shop owner: a small script that exports orders to a spreadsheet every night
  • Agency: a reusable starter template for client websites
  • Healthcare or legal office: a simple internal form that saves to a shared sheet

Step by step

  1. Install Cursor (cursor.com) or Claude Code, and open an empty folder for this project.
  2. Write a one-paragraph description of what you want in a file called README.md: who uses it, what goes in, what comes out.
  3. Open the AI chat panel and paste the prompt below, then let it propose a plan before it writes any code.
  4. Ask it to build the smallest working version first and run it. Paste any error message straight back into the chat.
  5. Test it with one real example from your work and write down what is wrong.
  6. Ask for one fix at a time. After each working change, save a copy (for example with “git commit”).
  7. When it works, ask the AI to write short instructions so a teammate can run it.

Ready-to-copy prompt

Write a clear task description for an AI coding agent: what to change, where, how to test it, and what “done” looks like. Task: [describe].

Tech stack

Everything you need to build it, get customers and get paid. Prices are public list prices, checked Oct 15, 2026.

1. Build

2. Get customers

  • X: post a short demo or before/after every day (free)
  • Reddit: answer questions in the subreddits your customers read; follow each subreddit’s self-promo rules (free)
  • Communities: Facebook groups, Discord and Slack groups in your niche (free)
  • Marketplaces: list it on Product Hunt, Etsy, Gumroad Discover or an app store

3. Make money

Model: Monthly subscription for a small tool

Suggested price: $19 per user per month

First 10 customers playbook

  1. Week 1: write down 30 people or businesses who clearly have the problem, and message 10 a day with a short demo.
  2. Offer the first 3 a free trial or a “founding” price in exchange for honest feedback and a testimonial.
  3. Post your demo and the first result on the channels above, every day for 2 weeks.
  4. Ask every happy customer for one introduction. Repeat until you have 10.
Monthly cost$0–$70/monthFree tiers → paid plans of the tools above. Card fees come out of each sale.
What you could earn · EstimateEstimate: 10 users × $19 = $190/moOur estimate, not a fact or a promise. It’s simple math if you land these customers at this price.

How to make money from it

Pricing idea: Sell it as a small tool: a one-time setup fee plus a low monthly price for hosting and fixes, or a self-serve plan from about $10–50 a month.

Finding your first 10 customers

  • Fix a real problem for 3 people you already know, for free, in exchange for honest feedback.
  • Post a short demo video where your audience hangs out (X, LinkedIn, Reddit, a Slack or Discord group).
  • Ask each happy user for one introduction to someone with the same problem.
