Five concrete examples of the Mortgage Calculator in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.

How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
