Trust scores, fake review detection, and adjusted ratings for Amazon products. 100% private, on-device analysis. **Stop trusting fake reviews. Start shopping smarter.** ReviewShield gives you an instant trust grade (A through F) on every Amazon product page, so you know at a glance whether the reviews are reliable or manipulated. No signup, no account, no data collection. It just works. **How it works:** ReviewShield analyzes reviews right on your device using 7 independent signals: verified purchase rates, review timing patterns, rating distribution, text originality, reviewer profile quality, incentivized language detection, and review length analysis. Nothing ever leaves your browser. **What you get (Free):** - Trust grade badge (A through F) on every Amazon product page - Detailed signal breakdown showing exactly why a product scored the way it did - Adjusted star rating that filters out suspected fake reviews - Individual review flags marking each review as Likely Genuine, Uncertain, or Suspicious - Category-based product alternatives with one click - Works on Amazon US, UK, Canada, Germany, France, Japan, India, and Australia **Pro features ($4.99/month):** - AI-powered deep analysis using on-device Gemini Nano (Chrome 138+) - Trust summary with a plain-English explanation of review authenticity - Smart highlights showing genuine pros and cons extracted by AI - Per-review AI verdicts with detailed reasoning **Why ReviewShield?** Fakespot shut down in July 2025. ReviewMeta went offline in early 2026. Millions of shoppers lost their only tools for evaluating Amazon reviews. ReviewShield fills that gap with a privacy-first approach that no competitor can match: - 100% local analysis. Your browsing data never leaves your device. - No accounts, no tracking, no telemetry. - Transparent scoring. Click the badge to see every signal that affected the grade. - Ethical affiliate links. Alternative product suggestions are clearly disclosed and based on review quality, never paid placement. Pro AI features require Chrome 138+ with on-device AI enabled. Most modern devices support this automatically. See our setup guide at loopheadlabs.com/reviewshield/ai-setup for details. **Frequently Asked Questions:** Q: Is ReviewShield really free? A: Yes. The free tier includes full heuristic analysis, trust grades, adjusted ratings, and review flags. Pro adds AI-powered features for $4.99/month. Q: Does ReviewShield collect my data? A: No. All analysis runs locally in your browser. We never see what products you look at. The only network request the extension makes is to ExtensionPay for Pro subscription management. Q: What Amazon sites does it work on? A: Amazon US (.com), UK (.co.uk), Canada (.ca), Germany (.de), France (.fr), Japan (.co.jp), India (.in), and Australia (.com.au). Q: What is the AI analysis in Pro? A: Pro uses Chrome's built-in Gemini Nano AI model to perform semantic analysis of review text, detecting unnatural phrasing, templated responses, and coordinated language patterns. This runs entirely on your device. Requires Chrome 138+ and a supported device. Q: How accurate is the trust score? A: ReviewShield uses 7 independent heuristic signals weighted by their reliability. No system is perfect, but our multi-signal approach catches patterns that individual checks would miss. Pro's AI layer adds semantic analysis for even better detection.
