Grammatik- und Rechtschreibprüfung - LanguageTool
Extension Actions
- Extension status: Featured
Rechtschreibung prüfen oder Texte umformulieren. Ganz einfach. Funktioniert überall im Web.
★ Findet viele Fehler, die eine normale Rechtschreibprüfung nicht findet
★ Keine Anmeldung nötig
★ Unterstützt mehr als 25 Sprachen (siehe unten)
★ Funktioniert auf fast allen Webseiten, auch Gmail, Facebook, Twitter
Mit dieser Erweiterung können Sie Text auf Grammatik, Stil und Rechtschreibung prüfen. LanguageTool findet viele Fehler, die eine normale Rechtschreibprüfung nicht finden kann, z.B. Probleme mit der Groß- und Kleinschreibung oder Wortverwechselungen wie Mine/Miene. Neben Deutsch unterstützt es auch Englisch, Spanisch, Französisch und mehr als 25 weitere Sprachen.
LanguageTool ist einfach zu benutzen: LanguageTool sucht automatisch im aktuellen Textfeld nach Grammatik- und Rechtschreibfehlern. Diese Erweiterung funktioniert fast überall im Netz: bei Twitter genauso wie auf Gmail (chrome.google.com wird derzeit nicht unterstützt).
Diese Erweiterung unterstützt die verschiedenen Varianten von Sprachen, wie z. B. österreichisches Deutsch und amerikanisches und britisches Englisch. In ein eingebautes persönliches Wörterbuch können Sie Wörter aufnehmen, die LanguageTool selber nicht kennt.
Anders als Grammarly (auch bekannt als "Grammerly" :-), Duden Mentor und QuillBot unterstützt LanguageTool mehrere Sprachen.

- Awful greedy company made a cheap move on all it's free users and honestly I will be telling everyone I know how garbage you really are and how over the last year you have been getting worse and worse.
- Matt Skujins
- Once was good... but now the company got greedy.

- Forcing AI into a free extension, then forcing the users to pay for that AI since it costs too much to run is really a new low. The extension ran fine while being community driven for years, but they couldn't pass up the chance to use AI, and now that it's not profitable, the user has to pay for premium...
- Sachin Bahal
- Using the extension is no longer free as of Jan 13th 2026, it's now part of a their premium subscription (which is paid), it's kind of a shady move to completely remove free access of the browser extension.

- they're making it so you have to pay for it to use as an extension now??? I don't even know where I can find something as soon as this one for me and now I can't use it-
- Harry Looney
- Love this app. I am a terrible typist so it helps me greatly!
- Руслан
- Your work is not a unique value, but merely a tool for those who don’t want to figure things out themselves. Users are learning, and soon many of your functions will become unnecessary: competitors will take them over. I won’t mind if they even slap on some ads — I’ll watch with pleasure. Developers often «bury» their projects along with their career ambitions — this cycle is inevitable.
- Eric Ketzer
- So in a few days, we won't be able to use it unless we pay for the Premium. Holy s**it....
- Bonnie Scot
- Used LT for as long as I can remember. Good few years anyway. To now make it premium (paid) to use the browser extention is REALLY below the belt. Lots of FREE alternatives out there. LT was just my go-to. It's my guess, they will live to REGRET that descision. Uninstalled.

- my top 5 app
- Maksim Burov
- Works very nice with multiple languages.
- Ceb Bec
- Incredible tool.
- Toni Bechlievski
- worked prety well, but they decided to offer only paid version so that is a no go for me. sorry
- CheekyRand0m
- Does what it says (with a cherry on top). A great alternative to most, if not ALL grammar checkers, spell checkers, paraphrasers, et cetera. Would recommend to an Apple or Google One user. Might need to loosen the Basic restrictions so you can squeeze at least some revenue from Basic users. 4 out of 5 stars.

- Invades privacy, isn't free anymore and requires a premium subscription to work, Harper is much better and also truely opensource.
- Kyd Ev
- Forcing a paid only version to include AI. That is just shameful. There's not even a less expensive AI-free version, that I WOULD HAVE SUBSCRIBED TO IF LESS EXPENSIVE. Now it's just hilariously expensive.
- Mohamed Laraiche
- Bad Marketing move you did. wasn't clean to "kick-out" user with this way even if im able to pay i won't pay with this way. specially there is TONS of tools doing the same. little or more not asking payment with this way :). good luck and try to check this way you put the limitaiton you will drop lot
- Evelina Nikolova
- made is paid only, subscription price is too high for what youre actually getting
- OlangaHD
- It was a great service until today, when the message appeared that it can now only be used with payment. I hope this decision will be reversed once more than ninety-five percent of users uninstall the extension. It’s a real shame, but it is what it is. Tip for anyone who now needs a free alternative: take a look at QuillBot. EDIT: They do actually link to QuillBot after uninstalling, which I find pretty fair.

- Now - paid only. Sorry there is a sea of free spellcheckers, bye.
- Wallace Dittman
- Be careful with this tool. Since they've switched to the paid subscription mode, it still disables your native browser grammar checker if you have LanguageTool installed. It means you may inadvertently skip a mistake. Delete it immediately, if you are not planning on switching to the paid model.
- Filip Korpet
- With mandatory premium, it's time to look for samo more healthy alternatives
- Darrell Dabney-Carter
- This Gemini newsiest tool addition and AI code assistant have improved significantly and added much-needed value to my project.
- Reynaldo
- Great app to learn new concepts for English learners.
- Ruben van hee
- I was looking for a spellcheck extension that was just that, no AI recommendations on how to phrase my own sentences, etc. This was it, no AI slop and bloat, just spellcheck. And it supports my main languages: Dutch, French, English and German. Recently has gone paid to use the extension and/or desktop app, but to me this is understandable considering the server costs they occur. So far they have been supported by the EU, so it might be this support is waning and they need to fund themselves. The API itself is still open source and available on github so, if you know what you're doing, and can follow instructions, you can still run the extension locally: https://languagetool.org/dev

- Suddenly not free anymore. Bye bye
- Mandeep Sachdeva
- Works perfectly and so easy to use I love the Chrome extension except the one problem I have is that app doesn't support most writing platforms.
- m jum
- Now only reserved for paid users, power and money hungry.
- Golfboard
- Developers are most likely paying, botting, and/or making positive reviews for this dog water extension. Probably trying to bury the bad reviews and keep the stars high so people think it's good and worth paying for.

- I like it for the most part, I did end up buying a yearly subscription, it's a lot less than Grammarly although Grammarly is better, imo, but its 3x the price. I would like to see an option to include certain words and their grammar in the dictionary. Some word I want to be capitalized and I don't like to continuously deal with the Grammar checker to clear the "error" of capitalization.
