The design is very beautiful and easy to use! The extension is so helpful. I was finding some pop up translation similar to how Rikaikun works but with languages other than Japanese and this is definitely it! Thank you.
Супер расширение, очень удобное и функциональное. Хотелось бы еще добавления альтернативных источников перевода, например, Яндекс переводчик и DeepL.

Очень редко пишу отзывы, возможно это мой первый отзыв для расширения хрома. Раньше часто использовал расширения для перевода отдельных слов/предложений по выделению, и, самое главное, чтобы перевод отображался во всплывающем окошке. Теперь потребовалось аналогично производить поиск по словарю, дабы узнать определение умных слов. Долго искал, и наткнулся на данный сабж. Это просто отличное расширение, которое полностью соответствует моим текущим потребностям: - Отображение результата во всплывающем окошке - Перевод - Поиск по словарю - Поиск по википедии - Поиск картинок - Гибкие настройки, как отображения, так и поведения 5 из 5! Рекомендую.
Best extension
Never seen an extension which helps you in all ways. Inbuilt researching with translation and defining and even images for reference, just WoW it is. I would just like to suggest an additional source of JSTOR.com. When you have Wikipedia, google, DuckDuckGo, Bing images, why not search for some articles or docs for further help, obviously to one who's interested.
This is unreal

제가 경험해본 팝업 사전중에 최고의 팝업 영어 사전입니다. 영한 사전 어휘가 너무 적은게 단점이네요.
