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

- Setting the same PIN on every lock
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 lengths are supported?
Any length you pick, with 4 to 8 digits covering most locks and card style codes.
Can digits repeat?
Yes - every position is drawn independently, so repeats appear naturally in the result.
Is the PIN stored anywhere?
No - it is generated in your browser and never logged or saved.
Are short PINs secure?
They carry limited entropy, so use them only where the system allows nothing longer and keep each one unique.
