Description
Couponly is an AI-powered coupon and promo-code tool that helps shoppers find codes that actually work. It uses machine learning and AI verification to check every code against real checkouts before you see it, then automatically tests and applies the best working code at checkout across a very large catalog of online stores.
Couponly is available as a free browser extension for Chrome, Firefox and Edge, as well as a website with store-specific coupon pages. The extension applies verified codes at checkout and can track prices on products you watch. The company emphasizes trust and privacy: it states the extension collects no payment details, keystrokes, form contents or raw page content, and never collects your browsing history, sending only anonymous signals about whether codes worked and optional product data for price history that you can switch off.
Both the website and extension are free, with no subscription or paywall. Couponly makes money through affiliate commissions when you shop using its codes or links, and states that commissions never raise your price and never influence how offers are ordered, since merchants cannot pay for placement and offers are ranked by freshness, measured success rates and price. Couponly is operated by a private limited company registered in Estonia.
