What it is
Stop screenshotting your stats notebook. A/B Test Results renders each variant as a horizontal bar with confidence intervals, sample size, and a clear winner annotation, so PMs and execs read the same number you do.
What it does
Plots variant means with 95% CI whiskers, annotates statistically significant winners, and surfaces sample size + lift % on hover.
Why use it
It moves the conversation from "which one looks better?" to "which one is real?" without a stats lecture.
