Lucidity is a Chrome add-on designed to promote sustainable shopping habits by flagging fast fashion products on Amazon. With the majority of Amazon's 310 million users unaware of the environmental impact of their purchases, Lucidity steps in to simplify the decision-making process. It evaluates clothing items based on material composition, manufacturing practices, and pricing to identify fast fashion items, thus empowering users to make informed choices without extensive research.

When an item is flagged as fast fashion, Lucidity offers users alternative options by providing links to secondhand marketplaces such as eBay, Facebook Marketplace, and Depop. This feature encourages users to consider sustainable alternatives, making it easier to shop responsibly. As a free tool within the browser, Lucidity aims to enhance the shopping experience by integrating sustainability into everyday consumer habits.
