마우스 사전 is a basic Plasmo extension designed to assist users in quickly finding word definitions while reading English documents. This Chrome add-on eliminates the hassle of manually copying and pasting words into a separate dictionary search. With 마우스 사전, the meaning of an English word is automatically displayed when the user hovers their mouse pointer over it.

In addition to providing word definitions, 마우스 사전 also offers a useful feature that shows previously visited products from online marketplaces. This can be particularly helpful for users who frequently shop online and want to easily access product information without leaving their current browsing session.

It's worth noting that to cover server and maintenance costs, 마우스 사전 may display recommended products from platforms like Coupang in exchange for a certain commission.

Overall, 마우스 사전 is a convenient tool for English language learners or anyone who frequently encounters unfamiliar words while reading English documents. Its intuitive functionality and integration with the Chrome browser make it a valuable add-on for improving vocabulary and enhancing the browsing experience.
