Good grammar spelling checker, but he missing some language like Bulgarian.

Muito bom, mas poderia ficar melhor. Se conseguisse instalar. A extensão cansa, de ir para lá... E para cá. Mas nada de instalar. Por favor não poluir o e-mail com robôs.

Very good, I like it better than Grammarly 'cause it's open-source.

It is way better than what I expected. It works everywhere automatically. Now I always now how to type a word even if I am not sure if I typed it out correctly.

This is amazing
