WHY IT'S DIFFERENT

Most calculators do a simple weighted average. Amazon doesn't.

Amazon doesn’t treat every review equally. Recency, verified-purchase status, and other signals can influence the rating shoppers actually see — which is why your displayed rating may not match a simple average.

Buzzy-1 closes that gap. Our AI model was tested head-to-head against the plain average on products it had never seen before, giving you a smarter estimate of the rating Amazon is likely to display.
