TatuAzul is a Brazilian shopping discovery and price-tracking platform designed to help consumers find deals and make more informed purchasing decisions. Its site brings together offers from retailers and marketplaces, displaying current prices alongside discounts and, where available, average-price comparisons and product price history. Shoppers can browse a broad range of categories and brands, explore trending products, and sort listings by factors such as price, discount, recency, or the platform’s HypeScore, which indicates how much attention a deal is receiving.

The service also provides tools and features for deal hunting, including coupons, a deal calendar, product tracking, notifications, personal lists, and a scanner. Users can sign in to manage their account and alerts, while feedback tools allow them to report inaccurate prices, expired offers, or other issues. TatuAzul states that it participates in affiliate programs with stores and marketplaces; purchases made through its links may generate a commission for the platform at no additional cost to the buyer.
