An illustrative example
A B2B security startup tested two homepage CTAs before a paid campaign: "Start free trial" vs "See it in action".
A six-persona panel modeling IT directors and security leads at 200-2,000 person companies.
- "See it in action" won 5-1: senior buyers didn't want an account, they wanted proof, and 'trial' implied setup work.
- Several personas said 'free trial' made them assume a self-serve tool too small for their stack.
- The reasoning surfaced a third option worth testing: a 2-minute recorded demo with no email gate.
The decision: They shipped the demo-led CTA and queued the ungated recording as the next test.

Frequently Asked Questions
What is an AI A/B test?
It shows competing message variants to a panel of AI personas and tallies which they prefer, with reasoning. It serves as a fast pre-test before a real A/B test or ad spend.
Does this replace a real A/B test?
No. It's a fast directional pre-test to pick the strongest variants to put in front of real traffic, so you waste fewer impressions on weak copy.
How many variants can I compare?
Two to four at a time works best for a clear read.
