Whiteberries is a free Chrome extension designed to streamline the online shopping experience by eliminating distractions such as ads and marketing tactics. It focuses on improving user experience by removing various labels and sections that often clutter product pages on marketplace websites. This allows users to concentrate on selecting their desired products without the interference of aggressive sales tactics.

Key features of Whiteberries include the removal of discount labels, timers for "best prices," stock level indicators, and recommendations for similar products. It also disables auto-play for animated covers on product cards. By implementing these changes, Whiteberries helps users save time and enjoy a more focused shopping experience, particularly on platforms like Ozon.
