Put your business on autopilot
Get a private little app for the task you repeat every week
Your client numbers stay on your own computer, because the finished tool runs with no AI at all.

Can AI build me a simple tool that keeps my data private?
Yes. Ask the AI to build a small tool as one HTML file instead of doing the task for you each time, then run that file in your browser. Claude fits best when you want to test the tool on screen before you save it. ChatGPT and Gemini also write the same kind of file. Pick this route when the data is private, like client fees, or when you repeat the job every week and want it to run with no AI and no usage limits.

Your prompt
Fill in your details. Skip any you like.
Claude and ChatGPT open with your prompt already typed in. Gemini can't be filled in from a link, so its button copies your prompt: paste it into the new chat.
The prompt that gets copied
I do this task by hand over and over: [THE REPEAT TASK, e.g. working out package prices for clients]. Here's what I type in each time: [WHAT GOES IN, e.g. client name, hours, hourly rate]. Here's what I want out: [WHAT COMES OUT, e.g. a total and a printable summary]. Build me a small tool as one single HTML file that does this job in my web browser. Rules: it must work offline with no AI, no logins and no outside services, so my data stays on my computer. Use big, clear labels a non-technical person understands, catch obvious typing mistakes, and add a Copy and a Print button for the result. Fill it with fake sample data so I can test it right away. Then tell me in two plain sentences how to save it and open it again next time. If anything about the task is unclear, ask me up to three questions before you build.
Describe a chore you do by hand every week, and Claude builds a one-file web page that does it for you. You save it and run it in your browser, so your data never goes back to the AI.
