I keep trying to sign in to my existing account as prompted in an email. It says to sign up, when I click, change to sign IN, enter my email address, click continue, it just flashes and goes nowhere. When I go back to email the message is still there. Even now I am logged in but still prompts me to sign up.

signup for an advertising commercial , lack instructions

It stopped working on Firefox.

does not work on firefox at all

Can't do spell check anymore, needs Premium. But getting a lot of features, which may Improve the writing, but looked behind a paywall.
Now it only shows me, that I have done something wrong, but doesn't show me that.
For a non English Native, it helped me a year prior, but not anymore.

Annoying. Gets in the way of me writing text.

Over the past few months, Grammarly has stopped working properly across all the platforms I use, including Gmail. I’ve tried uninstalling and reinstalling multiple times, but the issues persist. What’s more frustrating is the complete lack of accountability once they’ve debited your account for the yearly subscription fee.

Getting real human support is almost impossible—you're just redirected to "try this" or peer-help forums, which offer no real solutions. It feels like once they've taken your payment, they’re no longer concerned about providing proper service.

Even when Grammarly was working, it had inconsistencies—if I copied and pasted text between programs, the corrections would often differ. For a service that’s supposed to ensure clarity, they really need to take more responsibility for their own performance.

Just flat does not work. Nothing shows up. Try it with Reddit, nothing. Try it with Reddit Private, Does not work.

I would rate this higher, but the constant nagging to upgrade to premium is a non-starter for me. I don't appreciate having my composition constantly interrupted by bad highlighting just to advertise your premium product. Fix your UI or suffer more negative reviews. The way you've designed your app is absolutely unprofessional.

Terrible. It always points out non-existent "advanced issues", requiring a paid subscription to fix, and constantly rips up my perfectly-good text.

Furthermore, the UI is terrible. The only thing it is good for is a spell checker, but we all have these built-in.

Do not recommend.

Do you see all the sys info it wants and data it collects? Also, some reviews talk about constant advertising to go premium. No, i'll make do with AI Grammar Checker & Paraphraser – LanguageTool. And it's not as if I don't write well, it's just that now I let the it correct my errors.

Too much spam like "Auto-activation filters..." I didn't pay for that

Does not work. After signing into the website and my paid premium account, the add-on indicates that I am not signed in. I tried to get help from customer support but they couldn't fix it.

Used to be good, but now is constantly advertising "premium" features which were standard. Using LanguageTool now
https://addons.mozilla.org/en-US/firefox/addon/languagetool/

Used to like it, but with "premium suggestions" that can't be disabled it turned from helpful to insufferably annoying. Switching to LanguageTool, hope it'll be better. If not - I'll be better off without a grammar checker than with something that just doesn't like my writing style and won't shut up.

Only a 1 star for now because if your using dark mode, the red line for misspelled words doesn't show up anymore. :(

To note I'm using the extension Dark Reader and FFs own Dark Mode.

works, but much worse privacy than the mozilla's recommended languagetool addon (https://addons.mozilla.org/en-US/firefox/addon/languagetool/)

Pretty much all spellchecker extensions now suffer from this problem, but about half of the suggestions I get nowadays are not helpful and about one-quarter are simply wrong.

Paid extension after a while.
