★ Vindt veel fouten die spellingcontrole niet ziet.
★ Registratie is niet nodig.
★ Kent meer dan 25 talen (zie verderop).
★ Werkt op bijna elke website, waaronder Gmail, Facebook, Twitter.
Met deze extensie kun je teksten controleren met de gratis stijl- en grammaticacontrole LanguageTool. LanguageTool vindt veel fouten die een eenvoudige spellingcontrole niet kan vinden, zoals het verwisselen van die/dat/deze, zij/hun, onjuist spatiegebruik, het herhalen van een woord en het kan bepaalde grammaticale problemen vinden. Het ondersteunt meer dan 25 talen, waaronder Duits, Engels, Frans, Nederlands, Pools, Spaans en Russisch.
LanguageTool is eenvoudig. Met een druk op de knop controleert LanguageTool spelling en grammatica van de geselecteerde tekst. LanguageTool werkt met bijna alle soorten tekst, van elke bron, zoals sociale netwerken als Twitter of LinkedIn en online e-maildiensten zoals Gmail. Slechts een beperkt aantal sites zoals chrome.google.com worden momenteel niet ondersteund.
Ons doel met LanguageTool is om gebruikers een complete proeflezer te geven die grip geeft op de vorm en inhoud van hun tekst. Ook al is LanguageTool een essentiële extensie voor mensen met een andere moedertaal, het is ook slim genoeg om fouten te herkennen voor mensen die in hun moedertaal schrijven en helpt je je schrijfvaardigheid in het algemeen te verbeteren. Deze grammatica- en spellingcontrole werkt voor alle variaties van veelgebruikte talen; het onderscheidt bijvoorbeeld tussen Amerikaans en Engels. LanguageTool heeft ook een persoonlijk woordenboek voor uitzonderingen of woorden die je gebruikt, maar niet te vinden zijn in conventionele woordenboeken. LanguageTool herkent deze woorden dan voortaan.
Anders dan Grammarly ("Grammerly" :-) of QuillBot werkt LanguageTool voor veel talen en biedt vergelijkbare mogelijkheden.

- (2025-09-10) I had the paid version for two-years and used it mainly for email and Twitter. It let too many grammar errors go by, even if the sentence made no sense, so I decided not to renew it. Even for this simple review, I caught two errors that the extension didn't catch.
- (2025-09-09) love it
- (2025-09-09) Couldn't do my work without this extension!
- (2025-09-09) Fantastic!!!
- (2025-09-06) stellar product!
- (2025-08-29) This extension claims to have support for Norwegian, but it lacks the most basic words and is completely useless. It is also unable to auto-detect Norwegian if I have Norwegian and English selected as my preferred languages. Uninstalling immediately.
- (2025-08-27) Super
- (2025-08-26) Amazing extension. Simple, easy and effective. Works in every site and it is such a great tool for typing in different languages.

- (2025-08-17) too good.
- (2025-08-16) Love this, THANK YOU! Here's my review from my experience with Grammarly to sum it up: Grammarly is great if you want to a non-stop BUY PREMIUM pop-up in front of your face every time you make a mistake or even regular sentences in general that it thinks could be better. The free version is so incredibly annoying, unintelligent, and unhelpful, it did the opposite of make me want to pay for an upgrade and felt more like a virus than an extension. I tried the LanguageTool extension instead; INSTANTLY more helpful, less invasive, calmer colors, and no pressure to upgrade. They just provide a decent tool/service for free and offer better features for a price, totally fair, but they don't shove the offer your face more than they provide the tool/service!
- (2025-08-16) super helpful, I use it everyday
- (2025-08-14) very very helpful
- (2025-08-13) far better then grammarly! super happy!
- (2025-08-13) LanguageTool is a great choice for translation and grammar checking, but for writing tools, I recommend TinaMind's Wiseinks.

In short: LanguageTool is clean, smart, fast — and a must-have for anyone who takes their writing seriously.
- (2025-08-05) Fantastic grammar tool. I interested in the AI bits for the most part, but the extension itself does everything I want it to. It works seamlessly with just about every website and text box on Chrome. Except for this text box in the Chrome web store, ironically!
- (2025-08-05) Does not work at all.
- (2025-07-29) High CPU usage for about 2 days (up to 30%). Turned it off in Chrome. Firefox is OK.
- (2025-07-29) Winner
- (2025-07-27) legal

- (2025-07-22) Excellent. I type to quickly and errors galore, then it sorts them out, Very good indeed malc
- (2025-07-21) I gave it 4 stars because this extension really helps because so some big words are hard for me to spell and I have a really hard time with Grammar what I love about this extension is that it corrects all my mistakes so my writing can be perfect
- (2025-07-18) Worked great till they charged me two months in a row for a quarterly account. The extra charge doesn't show on my account page but the money has been taken from my bank account.
- (2025-07-17) I went to school while hiding from Dinosaur, lol, so spelling was a SOUND IT OUT lesson. This program helps with the ignorance of those lessons.
- (2025-07-15) Fabulous extension! Love it! I would like to have deeper control into what it checks, but this is not bad enough to take a star out of my review.
- (2025-07-11) I am very pleased with LT. I use it for Spanish manuscripts and it helps a great deal.
- (2025-07-11) Best writing tool
- (2025-07-09) Very useful
- (2025-07-09) This might be autocorrect.
- (2025-07-07) I liked it, remedies mistakes right on-point and the pro subscription is worth it.
- (2025-07-07) It's good, a little slower as compared to it's alternative. But it's core is open-source, it consumes lesser resources and it doesn't require an account to start using it. You may require to login to unlock more features. Also, there are less number of applications supported as of now, and I believe they'll soon resolve it. And few more good things are, the date is not shared outside our system, and we can select and deselect in which applications we want it to be ON. I request the developers to keep up the good work, and please add more applications to support, and bring faster updates.
- (2025-07-06) It's open source, no account needed, free, constant updates and new features, and easy to use!
- (2025-07-02) I LOVE IT💋💋

- (2025-06-27) top
- (2025-06-24) love it but it doesn't read the context of the paper making the paper debatably worse than before the ai edits it.
- (2025-06-22) I like it ,
- (2025-06-21) It works. It's fabulous, but it gets in the way of you typing anything in a box. It will NOT let you space ahead. It's so ANNOYING. I had to remove it after 1 day
