ClearSell is an AI-powered competitive intelligence platform for Amazon sellers. It analyzes publicly available competitor reviews, buyer search behavior, and Amazon's COSMO knowledge graph to help sellers find product opportunities, validate market entry decisions, and write listings that convert. Unlike keyword-based tools, ClearSell uses Anthropic's Claude AI to extract severity-ranked frustration patterns from up to 300 publicly available competitor reviews, map pre-purchase buyer anxieties from real Amazon search data, and grade listings against the 10 dimensions Amazon's Rufus AI uses to recommend products. The platform follows a 5-stage intelligence framework — Research, Validate, Differentiate, Launch, Defend — guiding sellers from product research through ongoing competitive monitoring. Core tools include the Frustration Finder (review intelligence), Rufus Grader (COSMO compliance scoring), Buyer Anxiety Miner (pre-purchase objection mapping), AI Copywriter (intelligence-driven listing generation), and Launch Verdict (GO/NO-GO product decisions powered by Claude Opus 4.6). Built for private label sellers, product researchers, and Amazon agencies managing multiple brands.
