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.

Mistakes to Avoid
- Confusing viewport size with panel resolution
- Expecting inches instead of pixels
- Comparing CSS pixels with device pixels
- Checking while the window is snapped small
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
What is the difference between screen and viewport?
Screen size is the display itself, while viewport is the area inside browser chrome that a page can use.
Why is my resolution lower than the box says?
Display scaling shrinks the logical size - the panel maximum and what the browser reports can differ.
Does it show pixel density?
Yes - the device pixel ratio tells you how many device pixels make up one CSS pixel.
Is this information sent anywhere?
No - the page simply reads your display values locally in the browser.
