Penny

Penny is an AI shopping assistant browser extension that finds cheaper alternatives to fashion items, auto-applies working coupons at checkout, and tracks price drops for online shoppers. Available for Chrome and Safari (Mac and iPhone), it scans a product page and matches alternatives on material, construction, and fit rather than just keywords, showing a similarity score so you can judge how close each substitute is. Penny works across 100+ retailers including Nordstrom, Aritzia, Lululemon, Reformation, Madewell, Anthropologie, ASOS, Nike, Adidas, and Zara. At checkout it automatically tests and applies discount codes without manual copy-paste, and it monitors items you have viewed to notify you when the price drops. Installation takes about five seconds and no account is required. Pricing is free forever with no subscription fees published. Penny is aimed at fashion and apparel shoppers who want to avoid overpaying, sitting alongside coupon and price-comparison tools but differentiating on visual/attribute similarity matching for clothing rather than exact-product lookup.

Online fashion shoppers use Penny to find cheaper clothing alternatives, auto-apply coupons, and get price-drop alerts.
