Pearch

Every shopper starts from zero on every purchase. Amazon's AI wants you to buy. Star ratings are gamed. The result is $850B lost to returns annually and nearly every shopper with at least one regret story. Pearch is a FREE Chrome and Firefox extension that fires automatically on any Amazon product page and returns an honest 1-10 score built from real review analysis: sizing signals, quality flags, fake review detection, and a plain-English verdict in under 5 seconds. No signup required. Connect Gmail and the score personalizes to your actual cross-retailer purchase history. Your return patterns, your fit tendencies, your brand track record. Signals no incumbent can build without destroying their own revenue model. The extension is the wedge. The dataset is the moat. The long-term play is an API layer that gives AI shopping agents the one thing they currently lack: cross-retailer purchase outcome memory. Pearch is building the semantic memory layer for agentic commerce. Live on Chrome Web Store and Firefox Add-ons. Amazon affiliate integration active. Built solo by a founder with 15 years in ad tech who got tired of watching platforms optimize for advertisers instead of users. Install free at pearch.app. No login. No signup. Just install and go.
