ReviewLens helps shoppers judge whether reviews are trustworthy. Emojery adds a separate public reaction signal that shoppers and non-shoppers can leave themselves.
ReviewLens is not a reaction extension. It is a shopping trust tool: the Chrome Web Store card says it analyzes product review patterns on Amazon, Walmart, eBay, and Etsy, then shows an A-F trust grade, authenticity score, and Reddit sentiment.
Emojery is the complementary signal. It does not try to detect fake reviews; it lets verified users leave an independent emoji reaction on the product or page itself.
ReviewLens is analytical. It inspects review patterns and outside discussion to estimate whether the retailer's visible reviews should be trusted.
Emojery is participatory. A user can react directly to the product page, independent of the retailer's review system and independent of whether they wrote a full review.
ReviewLens is built for product pages on marketplaces. Emojery uses the same reaction model across supported social, developer, video, and shopping surfaces. The reaction history and picker stay consistent as users move between contexts.
ReviewLens's listing says its analysis is local and account-free, which is a good privacy property. Its public store card, however, does not link source code. Emojery lets users inspect the extension itself.

"Are these reviews real?" is ReviewLens's question, and it answers it from the pile of reviews the seller already has.
"What did people think, outside that pile?" is the Emojery one, and it answers it from reactions shoppers leave themselves. Neither answer replaces the other, which is why the 2 extensions coexist on a product page. On Amazon the reaction strip sits right by the rating block; see Amazon reactions.
