English is not my native language, but I use English in my everyday writing. Where I am weak in my writing situation, Grammarly has done well, for me in improving the spelling and grammar in my letters.

Sometime the extension don't detect the text field, also sometimes it asked me to login when I already logged in!

I would have done much better in school if Grammarly was around 60 years ago.

Badly-written 36 MB addon which stops working after it is disabled and re-enabled, requiring reinstall. The company has very aggressive marketing and forces people to install this addon. In contrast, Linguix grammar checker works online without any addon. This addon integrates everywhere, thus sending anything what is typed to Grammarly. They don't care if it contains sensitive info.

I love this plugin for the tonality emoji feature alone. Great add on!
