I’m looking for a Chrome extension that automatically gathers complete product information whenever I open a product page on Amazon, eBay, Walmart, BestBuy, Target, and other popular retail sites. Core data points the add-on must capture: • Title, brand, product listing URL, and main image URL • Price, original price, discount % and any “Limited time deal” or similar promotion tags • Full description and category/keywords • Reviews summary (e.g., “4.5 / 5 stars (61.7 K)”) plus review count • Additional cues such as “1 K+ bought in past month” • Vendor/site name, city, zip code, and the date-time the data is grabbed Key requirements • One-click capture: a toolbar button that scrapes the open page and shows the parsed data in an overlay. • Export options: JSON download and copy-to-clipboard; CSV export is a plus. • Modular site support: keep selectors/config in separate files so I can add new stores later without rewriting core logic. • Clean code with comments, using standard Chrome Extension APIs, JavaScript (or TypeScript) and manifest V3 compliance. • Brief README explaining setup, permissions, and how to extend selectors for more sites. Delivery expectations A functional prototype that reliably extracts the fields above on Amazon and eBay, plus at least one of Walmart, BestBuy or Target, with clear instructions so I can test and roll out to additional domains.
