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.

It's really useful I like all that it comes with
