Worked example · illustrative

Better decisions start before the results.

Test a benefit-led opening screenshot against the current feature-led version, keeping other assets unchanged.

Gabriel’s take

Write the audience, metric and interpretation rule first. This planner does not determine statistical significance.

Try it on your app

Compare a workflow screenshot with a benefit-led version, holding the remaining assets constant. Decide how you will interpret the result before the test begins.

What this tool checks—and what it doesn’t

This plans a test; it does not calculate statistical significance, set a universal sample size or launch an experiment.

Where does my work go?

Text and images are processed in your browser. Research tools share a locally saved research project; listing tools share a separate listing project. Other text tools save drafts on this device when browser storage is available; the screenshot checker keeps files in memory only. Clearing browser storage can erase saved projects. Export important work.

Can Gabriel review the result?

Yes. Contact Gabriel with your listing and question to discuss the scope. Tool use is free; professional consulting is agreed separately. No data is automatically shared when you click Contact.
