In itself, extremely useful plugin that I use daily. However, newer versions are totally unusable. Clicking a suggestion does not change the text anymore. That is like the most basic thing it should do. I had to downgrade to an older version to get this working again. Currently using 8.899.0. More or less random older version that still works.

No funciona en català.

DO NOT INSTALL THIS

I used to love Grammarly. I tend to type too fast for my brain to process sometimes and I miss common things often. It always helped me out so I didn't have to reread everything again. But in the last 6 months or so, it's fixes don't even make sense. It wants me to change a word here and there that doesn't even make sense. It gives me incorrect spellings and insists my spelling is wrong, when I know it's not. I wish it were as great as it used to be, but it's gone downhill and I'll have to find something new.

After installing this add-on Firefox browser keeps crashing and stops responding. DO NOT INSTALL THIS.

Very limited and super annoying while trying to sell paid version.

It is a useful tool, but not the best of its kind. Using it for years, but random bugs and issues are killing me. It is not about hoping to fix; those are part of Grammarly.
Also, it seriously struggles with Gmail, and god forbid to use it in Outlook. It does not show or underline irrelevant things that you must click somewhere else to open them.

Grammarly, is first and foremost, a misnomer. If you would genuinely like grammatical help while writing, the best thing you can do is adjust the setting in the built-in grammar checker in Docs or Word to be more strict. Grammerly is not going to make your grammar better, and stringent adherence to a constant assured and direct tone strips the human variance from writing.

Grammarly strips your voice away from you. This is especially a problem in an era of AI detectors, where the featureless grey mush that is created through Grammarly has no more of a soul than AI, leading to your paper being at risk of being flagged, and likely you having to, at the very least re-do your entire paper.

Truly, there is no rating too low for me to give Grammarly. If I could give 0 stars I would. If I could give -5 stars I would.

The base Grammarly features used to be absolutely great. And for simple corrections, it still is helpful. However, it is absolutely intrusive with all the other AI recommendations that you can only view with a subscription. You get absolutely numb to all the squiggly lines it places under your writing. Unfortunately, it has been surpassed by better add-ons for these jobs.

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.
