Amazon Review Assistant is a Chrome add-on developed by tjyunmai365. This free tool is designed to help users easily capture and analyze reviews for Amazon ASINs (Amazon Standard Identification Numbers). With this add-on, users can gather reviews and organize them into Excel spreadsheets for convenient downloading. The tool enables users to perform multidimensional analysis on products, allowing for insightful and autonomous analysis.

It's important to note that currently, the Amazon Review Assistant add-on is only available for the Amazon US and UK sites. However, the developer plans to gradually expand its availability to other Amazon sites in the future. Stay tuned for updates on additional site availability.
