You can install the extension without an account
…but
You cannot use the extension without signing in. WTF ?!?

..what a huge breach of privacy, it's like holding a carrot in front of a horse to make it move forward, it's manipulative, and just a lie.

collects website data by modifing the body secton on EVERY website (inspect): data-new-gr-c-s-check-loaded="8.934.0" data-gr-ext-installed="" data-gr-ext-disabled="forever" , and sometimes gives commas in the middle of words.

Macht deutlich mehr Fehler, als dass es nützt...

Grammarly has become absolutely terrible recently. It consistently will add punctuation in the middle of words, instead of where it was suggesting. The Pro nagging is also uncalled for and just gets in the way of doing anything actually productive. I can no longer recommend Grammarly.

can't sign in for months, continue button does nothing.

Amazing add! Really helps me with my daily work

Pure trash since they added AI. Avoid at all cost.

Used to be good, now it gives out incorrect suggestions because they turned to AI. Doesn't load most of the time.

Pure trash it doesnt recognize greek lang at all....

The addon is good, but it causes UI freezing, especially on MacOS, and to fix that I need to switch to other application and then back to FF.

So awhile back just staying signed out and taking the few freebies they let you had was enough to let it live sitting there probably harvesting data or extrapolating or whatever word used to obfuscate how my usage gains them something. Then little annoyances grew and festered, like the suggestion popup starting to block more and more of the UI and causing real delays, less of this, more nag, more less, and less and less reasons to keep it around. Welp, one spellcheck and then you be a nagging me boy?! let me show you what ingrates gits when them britches gets too big and your booty ain't paying the rent no moe. Adios Grammar Nationalist Socialists let the purge of all things green begin! Whaaaagh!

Grammarly provides an excellent support for non-native English speakers. Thank you !
