Image from store Grammar and Spell Checker — LanguageTool
Description from store ★ Finds many errors that a simple spell checker cannot detect ★ No registration needed ★ Supports more than 25 languages (see below) ★ Works on almost any website including Gmail, Facebook, Twitter This free extension ensures that your writing is error-free via the grammar and style checker LanguageTool. LanguageTool detects many errors that a simple spell checker cannot, such as grammar issues, commonly confused words, and punctuation oversights. Additionally, LanguageTool offers style suggestions to elevate your writing: synonym replacements for overused words, concise rephrasing of wordy sentences, and formal alternatives to commonly used expressions. LanguageTool is designed with simplicity in mind, instantly analyzing your text as you type. It is compatible with most platforms, including social networks such as Twitter and LinkedIn, and e-mail services such as Gmail. With LanguageTool, our aim is to give users a full-feature grammar checker and proofreader that will enable them to have control and confidence over their content. While LanguageTool is a vital extension for non-native speakers, it also recognizes many mistakes that are frequently made by native speakers. This grammar and spelling correction works across several varieties of commonly spoken languages, and is capable of distinguishing between American and British English. LanguageTool also features a personal dictionary for exceptions or words that you might commonly use, but are not found in a conventional dictionary; it will learn to recognize these words for future grammar checking and proofreading. Unlike other services like Grammarly (a.k.a. Grammerly :-), ProWritingAid, and Ginger, LanguageTool supports more than 25 languages including English, Spanish, French, German, Polish, and Russian (see below for the complete list). Your privacy is important to us: By default, this extension will check your text by sending it to https://languagetool.org over a securely encrypted connection. No account is needed to use this extension. We don't store your IP address. See https://languagetool.org/privacy/ for our privacy policy. Please send bug reports or questions to https://forum.languagetool.org List of supported languages: English (Australian, Canadian, GB, New Zealand, South African, US), French, German (Austria, Germany, Swiss), Asturian, Belarusian, Breton, Catalan (also Valencian), Chinese, Danish, Dutch, Esperanto, Galician, Greek, Italian, Japanese, Khmer, Persian, Polish, Portuguese (Brazil, Portugal, Angola, Mozambique), Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, Tagalog, Tamil, Ukrainian, Arabic

    Since a couple of days, the pop-up changed to a dark mode color, which I like. But I noticed after clicking (LMB) on the underlined word, I can't replace the word with one of the suggestions (LMB). The pop-up closes, but the word would not be replaced. After reinstalling the add-on, the tool work for some words, but then stopped working again. Does the free version not cover replacing words anymore, or is this a bug?

I just a want bind to fix the issues. Auto capitalization, auto spell check, etc. Having to go through each individual issue in order to fix it is not that useful.

  • (2021-03-01, v:3.3.4) Mr JP: Problem while scrolling to the top of a page
    This extension have been great, but I recently noticed it was causing issues while scrolling on web pages. When I scrolled to the top of the page, 1 of 2 things would happen. 1. When I scrolled to get to the top of a page, usually an image or an ad video on any website would immediately flash on the page. 2. Or, when scrolling to the top of a page and upon getting to the top, the text would become blurry for a second then focus back to normal. I had to disable the extension because these issues were not only annoying the hell out of me, they were causing these particular pages to become sluggish. Once disabled everything is working fine again. One of the two issues would happen on most websites, about 98 percent of the time. Is there a solution for this, was there an update that caused this? I never noticed this until a few days ago, maybe a week ago. In the meantime I had to disable. Thanks

    It is quite frustrating to have to use the mouse for corrections. Usually there is an alternative keyboard shortcut to have the pop-up appear, but I cannot find any in this case. Is there something I am missing? And, if there is not at the moment, could you please consider implementing it? Many thanks for a very good product.
