The free analyzer above runs the same distribution check we'd use as a research team. It looks at the public rating histogram (1-star, 2-star... 5-star counts) and identifies patterns that indicate review-pattern manipulation:
- Cluster bursts: 90%+ 5-star reviews with almost no 3- or 4-star is statistically improbable for a real product.
- Off-distribution: A real product's reviews follow a recognizable shape — usually some negative or middling reviews mixed with the 5-stars.
- Time bunching: Bursts of reviews within tight time windows often signal incentivized review campaigns.
Specifically for office-chair
Office chairs commonly see fake reviews for cheap drop-ship brands. Real reviews discuss back support specifics, wheel quality on hardwood vs carpet, and arm-rest range. Generic praise without these is a flag.
