Describe a calculator, a form or a dashboard. Get a working one.

Say what the tool should do: a form that turns campaign inputs into a creative brief, a calculator for your quotes, a page that shows the status from a spreadsheet. A small team builds it in a project folder you own, tests it and tells you how to open it.

Build me a quote calculator: I type hours and a day rate, pick a discount, and it shows the total and a one-line summary I can copy. Keep it to a single page, test it, and tell me how to open it. Publish nothing.

Questions about small tool builder.

Do I need to know how to code?

No. You describe the tool in plain words and ask for changes the same way. The files are in your folder if someone technical wants to look.

Is this for building a website?

This is for small internal tools: a calculator, a form, a simple dashboard. For a full website, see the website builder job.

Where does the tool live?

In the project folder you chose, on your computer. Putting it anywhere public is a separate step, and it asks first.

Put a team on something else.
