Don't bother unless you already plan on paying for it. This is bad if you're using it for free.

If you don't pay, it will sometimes say something to the effect of "one more writing error detected", but you can't get it to elaborate or remove this notification without paying. It's infuriating to the point that I couldn't continue using it.

Keeps automatically changing language on me. Very annoying and there's no option to change it back.

This is a privacy nightmare, so obviously "Recommended" by Mozilla.

Dear lord..

It's not FOSS nor Open Source!

I guess it's useful if you're terrible at writing, and it's helped me fix a couple minor errors, but overall this tool is terrible. It recommends putting commas everywhere you could possibly think of, misses a ton of grammatical errors, and is generally not useful. The thing that drove me over the edge was when it would recognize "Dursley" and "Dursley's", but would correct "Dursleys" back to "Dursley's".

It's more of a nuisance than a help.

Türkçe neden yok? bu yüzden kullanamayacağım. :(

Now, we have to pay subscriptions. Go to Hell.

Not very good at the Basic level. Hard core sales to upgrade to the paid level. I already use Grammarly.

Works quite well, but the red warning message with supposedly further errors found, which you can only see in the premium version, makes the tool useless and confusing. Deleted.

Only Portuguese from Brazil is available.

It is sad that the add-on is no longer open source and does not make transparent what is read and transmitted to the server. Complete regression.

I'm so sad this add-on isn't working anymore. I've used this for over a year and it was incredible, even without accessing the paid tools. Today I starting working as usual, correcting some papers, and I saw the tool didn't catch very simple mistakes (one of the sentences was "I cook burger and pizza"). IDK what happened, but I'll be deleting the extention for now.

yes because "I like car" is ok. that what the AI wrote.

Perfect!

If you like all the text you write sent to advertisers and shady third parties.

Just take a look at their privacy policy, easily the creepiest extension I've come across so far.

Can't understand how it's still in the "Recommended" section. Mozilla WTAF.

I was not able to select British English, as used in Canada. Many different spellings.

Very slow to correct spelling and adds a lot of latency when writing.

Module complétement ridicule, ne connait même pas l'orthographe française, et quand on essaye d'utiliser la prétendue "intelligence artificielle" on obtient des phrases complètement tordues qui ne veulent rien dire. Parfaitement à l'image de tout système "d'intelligence artificielle", écrit des contre-sens, ne respecte pas les règles grammaticales, nul ! A éviter à tout prix.
