Before You Generate
- Write the goal in one sentence before you open the tool.
- Gather your real material first: facts, numbers, names and constraints.
- Decide what done looks like - length, format, tone and audience.
- Set aside five uninterrupted minutes; context switching costs more than the task.

A 10-Minute Practice Routine
- Two minutes: write the brief for a real task on your list.
- Three minutes: generate and read the result end to end.
- Four minutes: edit - real details in, generic lines out, opening rewritten.
- One minute: save the prompt and note one thing to change next time.
How to Know You Are Improving
Track edit time per result for two weeks. When it drops, your briefs are getting better. When it spikes, the cause is almost always a vague input - go back to the tip about writing the goal in one sentence.
Frequently Asked Questions
How is fuel cost calculated?
Distance divided by fuel economy gives fuel needed; multiply that volume by your price per unit for the trip cost.
Which fuel economy figure should I use?
Your own observed mpg from fill-ups beats brochure numbers - real driving usually sits a little lower.
Does it support litres per 100 kilometres?
Yes - switch the economy unit and keep distance and price in the matching metric or imperial system.
Is my trip data stored?
No - everything runs in your browser.
