Overview
Product summary
Review the store description, core capabilities, and common use cases.

Whether you are reading a complex article, studying a foreign language, or just need a quick synonym, this tool acts as your personal reading assistant.
Simply select any text on a webpage to instantly trigger the popup bubble.

Loving the app so far. Any possibility of adding Brave Search to the Sources?
Very good app, but could you make it function on the built-in chrome reader mode as well? I read a lot of articles using reader mode but the extension does not work there.
A must have! Please add to the sources: https://www.hackterms.com/ https://www.techopedia.com/dictionary
Tons of options, great features and wonderful design. Just perfect extension!
Крутая тема. Времени экономит массу, и это реально удобно, спасибо автору! В разы быстрее, даже если пользоваться горячими клавишами по гуглению, это расширение впереди. Редко оставляю отзывы, но тут не мог пройти мимо!
