AI Grammar Checker & Paraphraser – LanguageTool Extension

★ 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 :-), QuillBot, 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

Garbear (ID: 0000003cee47f38d) Voted 5 ★ - Updated 12/03/2024 Valuable extension, been a user subscriber in three browsers for sometime. Worth consideration if you write online often.

icon

Milovan Filipovic (ID: 000000480b994a7c) Voted 5 ★ - Updated 09/15/2024 Very useful; it's too bad it cannot detect overused words or wordy phrases. Now, that would be great. Otherwise, it's very good.

icon

Tashi (ID: 0000000b2fc98470) Voted 3 ★ - Updated 06/05/2024 Het is jammer dat de tool geen verschil kan maken tussen een bv Engelse zin dit in een Nederlandse tekst staat. Ook vind ik nergens hoe je van taal kan wisselen met het programmatje...

Roy Nwaisser (ID: 0000003762de2765) Voted 1 ★ - Updated 04/21/2024 Big problem. When you install this extension it says "Your text will not be stored" on the welcome page that loads. But read the privacy practices and linked privacy policy (https://languagetool.org/legal/privacy) which are on the extension's page. This extension not only collects every imaginable type of data, it also analyzes it. For example "If you explicitly ignore correction suggestions, we anonymously store the internal ID of this error rule and the text fragment underlined as incorrect and 15 characters to the right and left of it. This allows us to detect false alarms from our system and avoid them in the future." Anonymous or not, that snippet of text could reveal personal information, banking information, safety information, etc. Scary stuff. There are other concerning terms like this in their privacy policy. The extension may work well but you will end up divulging lots of information in the process.

Roman “#безцензури” Vynohradov (ID: 00000037ef75c161) Voted 3 ★ - Updated 04/19/2024 Все було чудово, поки після якого оновлення, не почало під час виправлення помилок кидати курсор постійно на початок слова. Я клацаю в місці з помилкою, щоб її виправити, а воно відразу на початок слова кидає. Писав розробникам щодо проблеми, але вже другий тиждень жодної реакції, тому сьогодні видаляю доповнення, бо воно тепер, фактично, підсвічує помилки, але не дає їх виправити взагалі.
