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.

- Ignoring case differences
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 are lines matched?
Each line is compared exactly against the other list, so wording and spacing must be identical to count as a match.
Can it handle long lists?
Yes - paste as many lines as you need into each box and the sections update when you run the comparison.
Does it change my lists?
No - both lists stay as pasted and the results are reported alongside them.
Are my lists uploaded?
No - the comparison runs in your browser and nothing is stored.
