Grammar and Spell Checker - LanguageTool by LanguageTooler GmbH
Review by Voytash
Rated 1 out of 5
by Voytash, 3 months agoI’ve been using LanguageTool for over 2 years and I really liked it — until about a month ago.
Recently, the extension started causing extreme RAM usage while typing. I have 32 GB of RAM, and during normal use I sit at around 18–20 GB. However, as soon as I start typing in a text field where LanguageTool is active, memory usage quickly spikes to 30–32 GB within seconds, which often leads to Firefox freezing or crashing completely.
This happens multiple times a day. In some cases, just 10–15 seconds of typing is enough to crash the browser. I even had to start writing messages in external apps (like Notepad) and then pasting them, just to avoid crashes — which completely defeats the purpose of using this extension.
What’s strange is that:
- this problem only started about a month ago,
- before that, I had zero crashes for over 2 years,
- I didn’t notice any recent updates that could explain this behaviour.
At this point, the extension has become unusable for me due to its massive resource consumption.
That said, aside from this issue, I really liked LanguageTool and I hope this gets fixed soon.

- Rated 1 out of 5by `cffx, 11 hours agoUgh.... What a disappointment. Pulling the rug out from under your entire userbase by putting all functionality behind a paywall without warning. Yeah, screw you buddy.
- Rated 1 out of 5by Firefox user 19967570, 19 hours agoIt seems the development plan was: "How can we charge more?" and someone replied, "Let's add AI." The result: the same old features and some limited, an expensive subscription. The product didn't improve enough to justify the change, but the price certainly found a way to increase. A creative strategy, indeed.
- Rated 1 out of 5by Nidelon, 2 days agoWell, you knew what you were getting into when you made the extension paid. Nobody uses your AI functions, you created the problem yourself and increased costs.
- Rated 1 out of 5by NoMercyRKR, 2 days agoAnd with it only being a premium subscription, it's not worth it anymore.

- Rated 1 out of 5by Firefox user 12287081, 5 days agoLoved this tool until this week. Some how for some reason it keeps thinking I want to write in Spanish instead of English. I found a place to change the language and made it English again. Still everything is in Spanish.
- Rated 1 out of 5by Agent_Smith, 5 days ago"We've made the difficult decision to limit the LanguageTool browser extension to Premium users only". and with that basis, I have made the very easy decision to remove your extension. Hint: just because 'AI' seems to be in every conversation doesn't mean you have to force fit AI capabilities into a spell checker. Too enamored with technology?

- Rated 1 out of 5by Infomanraf, 7 days agoI’ve used LanguageTool for many years and it was a core part of my writing workflow, especially in the browser.
The recent decision to move the browser extension behind a Premium paywall breaks that workflow significantly.
I understand infrastructure costs are increasing, but removing free real-time browser correction makes the tool much less accessible for long-time users.
Keeping the limited free tier (basic grammar/spelling) or offline fallback would make the transition much easier to accept. No, instead LanguageTooler GmbH chose to AI-wash their greedy, money hungry decision.
Goodbye, LanguageTool.
You were a really useful extension. - Rated 1 out of 5by Firefox user 19957142, 7 days agoIt USED to be good. But, instead of keeping good code that was effucient to run, the company behind this extension jumped onto the LLM bandwagon, and decided to force the costs of running that power-hungry junk onto the users. $15/month for a spelchekar — no way.
- Rated 1 out of 5by Vycer, 7 days agoAsking to use a premium account is predatory, just don't use AI.
- Rated 1 out of 5by SolarTara, 7 days agoMaybe if they didn't try to cram a bunch of bullshit AI into their existing decent language tool they wouldn't have insane server costs and to remove the free use version. I'll just move on thanks.

Blame AI all you want, but your extension is not that great, especially for languages other than English. - Rated 1 out of 5by shark_bloody, 8 days ago
- Rated 1 out of 5by Firefox user 19231021, 8 days agoYou're going down the IFTTT path, and no one will need you anymore. Greed will be your undoing.
- Rated 1 out of 5by Aner, 8 days agook that we can't have everything free, but that price only for a language check? au revoir

My dyslexia, isn't something I can't opt out of.
However, removing your extension from my browser, is and was the easiest decision I made.
