Example Output

Design an A/B Test for Pricing Page: Test whether adding social proof increases plan selection

code
We're testing our SaaS pricing page. Current conversion rate is 3.2% and we get about 15k visitors per month. We think adding customer testimonials near the pricing table will increase plan selection by 15%. What sample size do we need and how long should the test run?

The skill responds with sample size calculations (around 3-4k visitors per variant), duration estimates (2-3 weeks), and a complete test checklist covering hypothesis documentation, variant implementation, tracking verification, and guardrail metrics.


Generate Ad Headlines for Google Search Ads: Create variations for project management tool

code
We're running Google Search Ads for our project management tool. Current best headline is "All-in-One Project Management" with 4.2% CTR. Generate 10 new headline variations testing time-saving, team collaboration, and simplicity angles.

The ad-creative skill generates variations like "Save 5+ Hours Weekly on Project Planning", "Bring Your Team Into Sync", "The Simplest Way to Manage Projects", with platform formatting and performance notes.
