Great tool for English language, too bad you need premium for some errors and there is no support for Finnish language, but what you can expect from free addon. Hope this makes me better at writing english language.

Based upon my experience with the free version I upgraded to get the additional information. I use Firefox simply because it excepts this as an add-in. The language capabilities I would have to rate as outstanding. Nothing else that I've seen comes close. I know only some French and this is very useful when talking to someone who is French.

Il m'est très utile j'apprécie beaucoup!

Très simple à utiliser et efficace.
Seul regret: le prix de l'accès premium: 1 à 2 fr par mois serait accessible, au-delà, c'est un peu trop pour moi.

C'est le top,j'aime

tolle Hilfe !!!

This tool prevented me from posting on Twitter over what it listed as grammar errors. When I attempted to override it, I was taken to a website wanting me to buy the premium version. I removed the tool. spell checking and grammatical checkers should only "SUGGEST". Maybe I wanted to be grammatically incorrect.
