Detect fake Amazon reviews with an A-F trust grade on every product page. On-device AI, no account - nothing leaves your browser. Review Guardian instantly detects fake Amazon reviews and puts an A-F trust grade right next to the star rating - before you spend a penny. It's a private, on-device fake review checker: every analysis runs locally in Chrome using the built-in Gemini Nano AI model, so nothing you browse ever leaves your computer. No account, no sign-up, no limits. If you relied on Fakespot to check Amazon reviews, Review Guardian is a private, on-device alternative that picks up where it left off - with no servers and no tracking. ⚡ WHAT REVIEW GUARDIAN DOES • Adds an instant A-F trust grade to every Amazon product page • Flags suspicious patterns: unverified-purchase clusters, review bursts, one-time reviewers, and repeated or copy-paste wording • Recalculates the "real" star rating with likely-fake reviews stripped out • Deep Analyze: on-device Gemini Nano reads the actual review text and explains WHY a product looks suspicious • Works across 15 Amazon storefronts worldwide 🚩 THE RED FLAGS IT CHECKS • Review bursts - a large share of reviews posted within a few days of each other • Low verified-purchase ratio - many reviewers never bought the product • One-time reviewers - accounts whose only review is this product • Copy-paste wording - near-identical phrasing repeated across reviews • Generic praise - superlatives with no product specifics, the signature of paid reviews Each flag is shown per review, with the reason in plain English. 🔒 100% ON-DEVICE - NOTHING LEAVES YOUR BROWSER • No servers, no cloud, no telemetry, no analytics • No account and no sign-up • Your browsing and your grades never leave your computer • Powered by Chrome's built-in Gemini Nano (Chrome 138+), so AI analysis stays private ✅ EVERYTHING INCLUDED • Free - every feature unlocked for everyone • No paywall, no trial, no locked tiers 🔍 HOW IT WORKS 1.

Check the adjusted rating to see the score with suspicious reviews removed 🛡️ A PRIVATE FAKESPOT ALTERNATIVE Fakespot - the fake-review checker millions of shoppers relied on - was shut down on 1 July 2025. Since then, checking Amazon reviews has meant either trusting a server that sees everything you shop for, or going without. Review Guardian closes that gap a different way: because Chrome now ships an on-device AI model (Gemini Nano), the analysis can run locally, with nothing sent to a server. You get fake-review detection back - without giving up your privacy. 🎯 WHO IT'S FOR • Anyone who shops on Amazon and wants to avoid fake-review scams • Former Fakespot and ReviewMeta users looking for a replacement • Privacy-conscious shoppers who don't want an extension phoning home • Deal hunters checking products before Prime Day and the holidays ❓ FAQ Q: Is this the same as Fakespot? A: No. Review Guardian is an independent, on-device tool, not affiliated with Fakespot or Mozilla. It does a similar job - grading Amazon reviews for authenticity - but runs entirely in your browser. Q: Does it use affiliate links or change prices? A: No. Review Guardian never injects affiliate links, never changes what you see or pay, and never redirects your shopping. Q: Is my data collected? A: No. There are no servers and no analytics. Everything runs on your device. Q: Does it just say "fake", or explain why? A: It explains why. The A-F grade is backed by specific signals, and Deep Analyze spells out the exact red flags in the review text. Q: What do I need to run it? A: Google Chrome 138 or newer, which includes the built-in Gemini Nano model. No other setup. 📋 PERMISSIONS • Access to Amazon product pages - to read the reviews shown on the page and display the trust grade • Storage - to remember your settings on your own device That's it. No broad browsing access, no background tracking. 🔐 PRIVACY COMMITMENT Review Guardian collects nothing: no personal data, no browsing history, no analytics, no account. All review analysis happens locally using Chrome's built-in AI. Nothing you do in the extension ever leaves your browser. ℹ️ NOT AFFILIATED Review Guardian is an independent project and is not affiliated with, endorsed by, or connected to Amazon, Fakespot, Mozilla, or Google.
