Why it works
The story earns credibility by naming a specific, counterintuitive result: the winning CTA was one the team had planned to skip, which makes the mechanism concrete and memorable. The framing leads with engagement numbers going up, so Breakthrough is the right primary type, though efficiency gains in QA time are real and acknowledged. The quote is thin but the surrounding narrative carries enough detail to offset it.
Steal this
Use the 'variant we almost didn't test' narrative beat. Showing that the tool surfaced a winner that human instinct would have killed is more persuasive than a plain percentage lift, because it attacks the reader's core objection to handing copy decisions to AI.
