Grammatik- und Rechtschreibprüfung - LanguageTool
Extension Actions
- Extension status: Featured
Rechtschreibung prüfen oder Texte umformulieren. Ganz einfach und kostenlos. 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.
Standardmäßig schickt diese Erweiterung Ihre Texte über eine verschlüsselte Verbindung an https://languagetool.org. Wir speichern Ihre IP-Adresse nicht. Sie benötigen keine Registrierung. Einzelheiten finden Sie in unseren Datenschutzrichtlinien unter https://languagetool.org/privacy/.
Liste der unterstützten Sprachen: Englisch (Australien, Kanada, Großbritannien, Neuseeland, Südafrika, USA), Französisch, Deutsch (Österreich, Deutschland, Schweiz), Russisch, Ukrainisch, Asturisch, Weißrussisch, Bretonisch, Katalanisch (auch Valencianisch), Chinesisch, Dänisch, Niederländisch, Esperanto, Galizisch, Griechisch, Italienisch, Japanisch, Khmer, Persisch, Polnisch, Portugiesisch (Brasilien, Portugal, Angola, Mosambik), Rumänisch, Slowakisch, Slowenisch, Spanisch, Schwedisch, Tagalog, Tamil, Arabisch

- I've tried several different extensions for phrasing, grammar, sentence structure, spelling, etc - LanguageTool is by far the best of them all. It opens automatically on Gmail, Facebook, and everywhere else I type - you can go to a pop-out screen to practise a couple of ways you want to format your sentences/paragraphs and it tells you which is the best - AND sounds most like you! I highly recommend this, super easy to install, too.

- This app is one of the best language or grammar checking extension I have used so far. Whenever I download a extension, there are 2 things I look for. First is the smoothness and design or the extension. Next is the most important, how does the extension flow even if I do not use the purchased version. And this extension has done it perfectly. Well done to the devs.

- 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.

- 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.

- 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!

- LanguageTool is a great choice for translation and grammar checking, but for writing tools, I recommend TinaMind's Wiseinks.
