Offline Secondhand Item Pricing Tool with Multi-Platform Support

ResaleIQ is a fully offline browser-based tool that helps users price secondhand items for resale across platforms like eBay, Facebook Marketplace, and Craigslist. Users answer four steps of questions about category, condition, age, and selling urgency, then receive data-driven price ranges calculated using category-specific depreciation curves. The tool also generates optimized eBay listings with SEO titles and descriptions, plus curated selling tips. Everything runs locally in the browser with no server connection, data transmission, or account required.
