Opened download file and it was some map quest app or something.

Does not save or sync with the dictionary. The AI they have to help is a moron.

Prioritizing greed over It's long time users, or this just your bait‑and‑switch, Either way you've lost me and you should also be removed from Firefox recommended list.

Originally my rating was 5/5 stars; as of 08/06/26 I've now revised that to 1/5 Stars.

LanguageTool has genuinely been one of the most useful extensions and tools I've used in the past year or two. Sadly, the team has decided to lock the ENTIRE extension behind a paywall (with no "lite" or "freemium") version, I seriously can't even get the extension to pop up?? It's just not worth the price right now, but also I couldn't even pay them if I wanted to???

I wish they'd have taken a page out of the DeepL team's book and made it so LanguageTool was an available option for the Firefox Browser Sidebar. I can kind of understand locking the original functionality down, but now I have to have a whole separate tab open to their main desktop website if I want to use/check any part of it??? this whole update and functionality change is just... odd.

For the record: YES; I would actually consider paying for LanguageTool if the extension had more integration on Firefox and other platforms I'd love to use it on, like iOS*!

I do hope it see it improve at some point. The slow decline of LanguageTool makes me sad. I hope I can come back and edit this review to be more positive in the future. For now, I'll be looking for an alternative extension and recommend others do the same.


(*which I have my own gripes about.... mainly that giving LanguageTool my "full keyboard access" removes their non-Apple keyboard functionality of it Entirely for some reason? why does giving them Keyboard Access remove THE ENTIRE LANGUAGETOOL KEYBOARD? why does it get replaced with some shoddy, clunky, and laggy window that takes forever to spellcheck anything? This lack of truly integrated or easily accessible functions seems to be a pattern with LanguageTool right now and it does NOT help the "mandatory payment for our whole app/extension now" sting... sorry to sound harsh to a product i used to love but wow. it's disappointing)

La aplicacion ahora te obliga a pagar para su uso, denunciar y desinstalar.

Totaler Mist was jetzt abläuft das man dafür bezahlen muss. Lasst doch die Leute bezahlen wenn sie zusätzliche KI Dienste haben wollen. Ich brauche das nicht aus diesem Grunde habe ich diese Erweiterung aus meinem Slimjet Browser (Chrome basiert) deinstalliert. Ich brauche nur Rechtschreibprüfung und Grammatikprüfung. Aus diesem sehe ich nicht ein extra zu zahlen für KI Dienste. Das eure Schwesterfirma eine kostenlose Alternative bereit hält ist gelogen. Wenn es auch in Firefox passiert werden ich die Die Rechtschreibprüfung und die Grammatikprüfung in Open Office machen. Ich arbeite dann mit Copy and Paste.

It's announced that the whole extension is going to be locked behind the Premium subscription. While I understand the need to make money, the costs are not reasonable for me and my usage. I also don't like your explanation that this is because of the rising costs of the AI-features, which I didn't need nor was convinced of to begin with.

You can circumvent this (for now?) if you set up your own server, but I think I prefer to part ways at this point.

Really used to love this until it started using gen AI more and more and kept finding more errors in its checks.

Just like grammarly pushing the premium very hard. I'm not going to pay for this.

One free grammar check, and then if I want to keep going I need to get a subscription... what's even the point of this "free" add-on?

Extension is now premium-only. A shame, because I was a consistent user before then, even getting premium once or twice when I could afford it. Unfortunately, I have other things I need to pay for, and a spellchecker is very much not a priority. I will be getting back to my browser's default spellchecker.

thye now wa t to be just premium nothing is for free i guess

It does not know the difference between there and their.

Stopped working!

I just want a translation. I should add additional features for a price, not remove the basic. Enjoy your fall.

Does not recognize many common words - especially names, scientific terms, and loan words from other languages. This would be fine if it happened occassionally, but it happens *constantly* and with plenty of words that aren't names or loan words.

Additionaly, almost every time it's given me a grammar recommendation, it's been wrong. There is no way to tell it that a suggestion is incorrect - the only option is to disable the rule entirely.

I thought I had gotten this spellchecker specifically because it wasn't AI (that's why I stopped using Grammarly). Another review mentioned that the AI label only appears in the extension name after you install it, so I'd guess that's what happened and it took me a while to notice.

Overall, poor quality and deceptive.
