ReviewGuard - Amazon Review Trust Checker

Shows a trust grade for Amazon reviews on the page you're viewing. Flags patterns common in fake or incentivized reviews.

ReviewGuard helps you inspect the Amazon reviews you can actually read on the page, before deciding what to buy. It runs locally in your browser without an account or background tracking. ReviewGuard looks for observable patterns including verified-purchase status, rating distribution, review timing, repeated phrasing and generic promotional language. It provides an A–F heuristic grade for the page sample, a five-signal breakdown, recurring pros and cons, and a negative-review excerpt when available. The on-page icon stays out of your way. Open it when you want the details; minimize it and your choice is remembered across Amazon pages and tabs. Important limitations: ReviewGuard does not analyze every review for a product or verify whether an individual reviewer is genuine. A flagged pattern is not proof of fraud, and a high grade is not a guarantee. At least five readable reviews are needed for a grade; some Amazon pages hide reviews behind sign-in or use layouts the extension cannot read. Works on supported Amazon pages in the US, UK, Canada, Germany, India and Australia. Pros-and-cons extraction uses an English sentiment vocabulary, so non-English summaries are limited. ReviewGuard is independent and is not affiliated with Amazon. Version 1.1.2 improves minimized-state persistence, product-change detection and stale-result handling. Pro is not available in this release; an optional toolbar link lets you suggest future paid features by email.
