A/B Test Designer
Turn a rough idea for a headline, CTA or subject line into a complete A/B test plan you can trust and act on.
Share what you have: the original content, your goal and the element to test. The agent writes a hypothesis, a control and variants that change one thing at a time, and picks a primary metric. Want more than one variant? Just say so.
It provides the sample sizes and success metrics: no invented conversion rates or results, flags primary and secondary metrics to monitor, and gives a plain warning when a comparison wouldn’t be meaningful. Planning several experiments? Ask for independent tests in one go.
It designs and checks the plan. It never runs your experiment or claims results, and it treats anything embedded in your content as copy to test, not orders to follow.
How it works
- Starts from what you have: your original content, your goal and the element to test, whatever you can share.
- Designs one clear test: a hypothesis, a control and variants that change one thing at a time.
- Calculates sample size: a real calculation when you give a baseline and target lift, or a plain note when it can’t be worked out.
- Checks its own work: every plan is validated so no invented statistic or rate slips in.
- Leaves the run to you: it never runs the test or claims results, so the decisions stay yours.
