Butter – Smart Size Finder (Chrome Extension)

Butter is a Chrome extension that helps users find the perfect clothing size while shopping online. By storing a user’s preferred sizes and measurements locally in the browser, Butter intelligently analyzes brand-specific size charts and highlights the best fit directly on product pages.

The extension integrates seamlessly into popular retail websites like Nike, Zara, H&M, and ASOS, adding a simple “Show Me My Size” interface near size selectors. It eliminates the need to manually read confusing size charts and reduces the risk of ordering the wrong size.

With a strong focus on privacy, all user data is stored locally and never sent to external servers. Butter enhances the online shopping experience by improving confidence, reducing returns, and making sizing consistent across different brands.
