The more I use it, the more I like it, especially when you're typing in different languages, nothing compares to this. Not that I have found.
I think that the price for a private single person user is too expensive so I will not subscribe now but I take my hat off to you for what you are offering.

--- Original Review ----
I don't understand how people rate this with any stars.. I just installed it, tested it. with:
How am I going to know if this work or not
1) it didn't mention that I had no period at the end of the line
2) it didn't complain that 'work' is not conjugated correctly.
But it did mention that there is '1 more writing issue found', learn more, but then I have to pay 4.99 a months to see the suggestion I guess..
I don't get it, or did I do something wrong ?

The reply from the developer is just as funny as this extensions inability to pick up the two errors above. Buy the premium version or fix the free version yourself ;-)

Ist sehr hilfreich, wenn man Fehler nicht sofort bemerkt!

An absolute recommendation from me! Helps me in my daily work and everyday life to improve texts and learn at the same time. The implementation in almost all apps and programmes makes it versatile. In addition, it can improve many languages. Top!

Alles OK Supper

Very useful add-on

Get's the job done and works really well

The LanguageTool plugin works well; however, I have noticed that this plugin is inferior to the LanguageTool editor. I can apply all corrections from the plugin, then paste the corrected text in the editor and find additional corrections. I would have expected the same performance for both the editor and the plugin.

Note: I found the same issue with the Thunderbird plugin and added the same comment there.

Simplesmente incrível, gostava muito do grammarly, porém, ele não possuí suporte ao português. Uma extensão indispensável para todos.

Cada día mejor en español

Классно находит ошибки и смыслы и помогает их поправить

Что то у меня складывается двоякое впечатление, что с каждым обновлением идёт ограничение возможностей... специально сделал простую ошибку и корректор не справился, то есть даже близкого варианта не дал (яндекс исправил сразу) ➜ https://i4.imageban.ru/out/2021/11/28/ef517302342ae81ff5e87be747a27eb7.jpg
Хотя раньше подобного не было.
Плюс к тому же ещё одна неприятная ситуация... После обновления до версии 4.4.0 браузер стал дольше загружаться... моё мнение, вина тому встроенный таймер рекламы (зачем он?)

Скорость загрузки браузера на позапрошлой версии...

P.S.
Вот и спрашивается, зачем мне продолжать пользоваться вашим приложением, если производительность браузера стала падать, плюс явное занижение возможностей приложения.
----------------------------------------------------------------------------------
I have a twofold impression that with each update there is a limitation of possibilities... I made a simple mistake on purpose and the proofreader failed, that is, I didn't even give a close option (yandex corrected it right away) ➜ https://i4.imageban.ru/out/2021/11/28/ef517302342ae81ff5e87be747a27eb7.jpg
Although there was no such thing before.
Plus, another unpleasant situation... After upgrading to version 4.0, the browser took longer to load... my opinion, the fault is the built-in advertising timer (why is it?)

Browser loading speed on the version before last...

P.S.
So the question is, why should I continue to use your application if the browser performance began to drop, plus a clear underestimation of the application's capabilities.
===================================
Дополнительно: Ответ разработчику...
Ну да, давайте приплетать систему, а на втором компьютер проблема тоже характерная для моей системы? Та же проблема, замедление запуска браузера на несколько секунд...
Так что проблема в вашем дополнение, а конкретней в рекламном таймере.
-----------------------------------------------------------------------------------
Additionally: The answer to the developer ...
Well, yes, let's tie in the system, and on the second computer the problem is also characteristic of my system? The same problem, slowing down the launch of the browser for a few seconds ...
So the problem is in your add-on, and more specifically in the advertising timer.
