Amazon Review Guardian

About

Amazon Review Guardian is a lightweight browser extension that helps users detect trustworthy reviews on Amazon by assigning letter grades (A–F) to individual reviews based on their content and trust signals — without scraping or violating platform policies.

What It Does

- Grades each Amazon review from A (most trustworthy) to F (least trustworthy)
- Adds visible colored badges directly next to each review title
- Helps shoppers make smarter decisions based on review quality, not just star ratings
