I am honestly not impressed with this add-on at all. Everybody always talks about Grammarly and how fantastic it is, but it honestly is far from great in my opinion. It always tries to correct basic grammatical mistakes that are, in fact, not mistakes, as well as neglect to correct mistakes that are, in fact, there. I would personally prefer Linguix, which isn′t perfect either, but definitely better than this. Everything about this add-on is decent but it′s little mistakes like the ones I mentioned that it makes that prevents me from using it.

It interrupts my writing session by repeatedly asking me to log back on to Grammarly. It doesn't stay logged in.

nice

I like the exstention, tough there is one flaw I've noticed when Using it with Firefox...
If I right click on a word that Grammarly selects to "correct" it there is a 70% chance that the word isn't changed but gramerly pastes the correct spelling at the location where my cursor is... this isn't useful at all (example, I write "hello, how is you day going" and it should correct you to your, if I would correct that after typing going grammerly would change it to "hello, how is you day goingyour" :/)

pas encore tester!

difficult to get installed

It is a basic help tool. As a spell checker, it is ok but will not catch your context issues. As a grammar checker, it is superior to me, but does not catch active versus passive problems. Quick and easy

Grammarly Free worked very well for a few weeks, then stopped. It has been uninstalled and reinstalled, the add on has been uninstalled and reinstalled, and still refuses to work. This is on both a laptop and a desktop. Very disappointed.

It works, but it would be better if they let you login in to use it while typing this review.

Works very well until it doesn't. it worked for a few months then suddenly stops.
