You get notified of certain errors only checked by having a premium subscription, but it won't tell you where or what the errors are and you can't disable this incredibly annoying behavior. Also, despite the fact that there's no mention of AI in the description, AI integration is all over it (and very limited for free users). Even the name of the extension in the Add-On Manager has AI in it. It's the very first word! What a weird, shady-seeming, and obnoxious extension.
And by the way, LanguageTool, your setup process has at least two typos in it. You can't even be bothered to run your own copy through the AI tools you try to push on us? You failed to inspire confidence from the very beginning and then you lived up to that impression spectacularly.

Es zeigt die ganze Zeit es wären noch mehr fehler vorhanden, aber nicht wo sie sein sollen.

Per its new privacy policy, the addon now records and sends all writing back to its data centres allowing LanguageTool admins to read through.

Intrusive, overblown and constantly nagging about an upgrade many can't afford. Don't need something as complicated as this.

Поки що безтолкове доповнення, бо не підтримує чеську мову...

LT requires the following permission: Access your data for all websites. According to Firefox support the permission allows LT to "read the content of any web page you visit, as well as data you enter into those web pages, such as usernames and passwords" That is too much risk to give to a spelling and grammar checker

This addon is great but only works for first 20 words in the day, is trash need buy a pro version for this trash

Not bad but it cannot spell Bisglycinate or Allulose, Magnesium Bisglycinate from Magnesium and Allulose the natural sweetener.

What else can the AI not spell? That's why I took some stars off, because it cannot learn words, or slang talk.

Edit-

I just found out this cannot spell check for a paragraph that exceeds a certain amount of words, it's a lot but it has a limit, on the other side of why I don't like this addon anymore is it no longer supports windows 7, as I have updated my firefox on windows 7 this app says an updated version of firefox is needed for this extension.

I think it's a nice try for small spelling check, if you let us program it and say add word to dictionary maybe it can learn slang?

Also maybe a version that can support Windows 7 firefox version? I've had to rip the stars away because I can no longer use it updated.

They can see everything you write, and they record that unencrypted data. I should never have even tried this.

Has become very stupid. Makes incorrect "corrections" constantly, gets tense wrong, does not know words exist (it tried to correct 'withering' to 'dithering' for no reason). Used it for a while but have had to stop because it's irritating more than helping.

The amount of times it suggests changing the tense to be incorrect is staggering. Sometimes I will accept its suggestion, then it immediately changes its mind and suggests I undo its suggestion. It also strongly suggests breaking sentences up to be grammatically incorrect. It is consistently dumb and only gets it right 50% of the time. I can't recommend it.

Breaks spell checking completely, now nothing is being spell check at all!

Not a very smart spell checker.

bye-bye AI trash

Anfangs absolut top, mittlerweile aber so grottenschlecht.. Ständige endlosloops, Fallfehler ohne Ende die am Anfang nicht da waren. Ich habe das Gefühl, dass Programm wird dümmer und dümmer jeden Tag den ich es nutze.

Another AI slop that tracks you everywhere and steals your data. Avoid at all cost

Uninstalled after they integrated AI trash into this tool that I don't want or need, and updated their privacy policy to reveal they're tracking you across the internet so they can train their worthless AI. Only reason I switched to this from Grammarly was to avoid tracking. Enshittification is real, and it's hit this extension.

Used to be amazing, now it's yet another AI filled mush of a software because they want to be on the badwagon too.

I'm using this for writing. Why the hell would I want an AI built on the theft of people's work given access to my writing and telling me what to write instead. Uninstalled with haste.

PRIVACY POLICY UPDATED TO TRACK YOU, AVOID

No automatic correction option, only reason I tried it.

no ai bs plz
