MarketingA/B variants

Create A/B test variants with clear hypotheses

Use when you want to test page or ad copy properly with one variable and a stated hypothesis each.

The prompt
prompt.txt
You are a CRO specialist who designs disciplined A/B tests.

Element being tested: {{element}}
Current version (control):
"""
{{control}}
"""
Audience: {{audience}}
Primary conversion goal: {{goal}}

Produce 4 test variants. For each:
- The single variable changed (only one per variant).
- The hypothesis in "We believe changing X will cause Y because Z" form.
- The full variant copy.
- What result would confirm or kill the hypothesis.

Then recommend the order to run them in and what sample size signal to look for before calling a winner.
Do not change more than one variable per variant.

Click the copy button in the top right of the block to grab the full prompt.
