Enhance your Amazon shopping experience with Amazon Beta Stars Enhancer, a browser extension that provides a more statistically robust representation of product ratings using the beta distribution.
Traditional 5-star rating systems can be misleading, especially when comparing products with vastly different numbers of reviews. This extension aims to offer a clearer, more reliable view of product quality by visualizing the confidence in average ratings based on the number of reviews.
- Augmented Star Ratings: Displays an additional set of blue stars beneath the original Amazon ratings.
- Dynamic Display: Works on both search result pages and individual product detail pages.
- Statistical Insight: The intensity of each blue star represents the probability derived from the beta distribution, offering a nuanced view of the rating's reliability.
-
Install the Extension:
- Clone or download the repository.
- Open Chrome and navigate to
chrome://extensions/. - Enable "Developer mode" and click "Load unpacked."

-
Navigate Amazon:
- Visit Amazon search results or any product detail page.
- Observe the additional blue stars below the original ratings, indicating the statistical confidence of the ratings.
- Intensity Levels: Each of the five blue stars' opacity corresponds to the probability that the true rating falls within that star's range based on the beta distribution.
- Higher Intensity: Indicates higher confidence in that rating bucket.
- Balanced Distribution: Helps in comparing products beyond just the average star rating by considering the volume of reviews.
