Goodreads Fit is a Chrome extension designed to enrich the Goodreads experience by analyzing book ratings with advanced statistical models. This free add-on enhances each book's page by displaying an extended rating above the review section, along with a bar-chart that users can click to explore various statistical models and their graphs. The extension aims to provide a deeper understanding of how book ratings are distributed, making it easier for readers to assess the popularity and reception of a title.

One of the notable features of Goodreads Fit is its ability to detect 'review bombing' and perform statistical comparisons using information criteria like AIC and BIC. By offering insights into the rating distribution, it helps users make more informed decisions about their reading choices. The functionality of the extension is easily accessible through its icon, allowing users to dive into the detailed features with just a click.
