Is really useful, 'cause I'm learning English and this extension help me to correct some grammar mistakes.

It also works in my native language

Melhor extensão não há, facilita muito a vida de quem não tem acento no teclado.

Very helpful

LanguageTooler GmbH, it's great for someone like me. Math came easy, but the rest was hard for me in school. I am in my middle 60's and with all this correct speaking, it goes over my head.

Great software, but it needs a lower price.
