BuyWise fills the void left by Fakespot's shutdown with its comprehensive fake review checker. This browser extension works seamlessly across popular shopping platforms such as Amazon, Walmart, Target, Best Buy, and eBay without requiring users to copy-paste URLs or create accounts. It offers an A-F trust grade for each product based on verified purchases, review velocity, rating patterns, and sentiment analysis. The free version provides these insights, while the Pro tier includes AI-powered analysis explaining why a product received its score.
