Долго искал такой многофункциональный переводчик. К тому же у меня есть api-key для нейронок. Большое спасибо разработчикам

非常糟糕！绝大多数内容要求注册登录账号才能使用。且虽然在chrome商店里的介绍页有中文，但实际安装后界面语言不支持中文。
SUPER GREAT.
This is the best extension ever. I have learned so much from this tool and it makes difficult and technical reads so much more enjoyable. Not to mention its intuitive interface, the people that created this extension must be awarded a Nobel Piece Prize!!!
Considero-o um dos melhores até agora. Sua utilização é simples e extremamente prática. Com a integração de pesquisas na internet, você acessa tudo diretamente em um pop-up, sem precisar sair da tela atual.
так долго искала подобное расширение, которое не будет перегружено, будет понятно и будет работать, вы не представляете. спасибо!
Muito bom para quem estuda por PDF e quer enriquecer o vocabulário. É basicamente um pack do que se usaria abrindo outra aba, mas essa Extensão facilita com os "dois cliques" na palavra. Excelente!
Прекрасное расширение, очень удобное и функциональное
an absolute masterpiece
