Wenn es nicht oft die falsche Sprache erkennen und dann alles als falsch markieren und sinnfreie Vorschläge machen würde oder man die automatische Erkennung ausschalten könnte, wäre es richtig gut. Ich habe Muttersprache Deutsch und bevorzugte Sprache Deutsch und dann kommt es mit Niederländisch daher und macht alle Vorschläge in Niederländisch.

Nachtrag zur Antwort.
Danke, das habe ich schon mal gemacht, brachte aber keine Lösung. Das Problem tritt vorwiegend bei Google Notizen auf und selbst wenn man händisch auf Deutsch stellt, ist es nächstes mal wieder Niederländisch. Am besten wäre wohl, die automatische Erkennung auszuschalten.

Just started using it. We shall see.

Excellent product. However, not satisfied with the add-on. The inline pop-up closes every time the page is scrolled. My display is 1280x, and I use a mouse, and i will have to scroll to see the language suggestions. It becomes very annoying to reopen often. Need an option to close manually only using the close button, it should not close on page scroll. It also sometimes closes itself, when fetching paraphrasing suggestions, must be a bug.
Update: Posted, and pending.

After 2 years, it mostly cannot detect and disable checking when writing in unsupported language (Czech).

I would rate 5 stars but I think you should be able to turn of the notification that the text has advanced errors. I understand that they need a subscription of that but I think we should have the option to not accept, I would rather it just ask me if I wanted to upgrade every once in a while rather than always tell me that there is a problem and not telling me how to fix it.

It works nicely, but since the 13th of July update, I have a constant "!" warning when I write a text and I have to click it then click "I understand" in a separate page like 10 times a day, I don't know why it was perfect before...

It will work almost all the time when correcting your spelling, but many times it misses the grammar, hence not as polished as Grammarly.

Example:
OK, so I write the text, and it will correct me attempt (this sentence is correct according to LanguageTool

However, according to Grammarly it corrected my text to (OK, so I write the text, and it will correct 'my' attempt) which, I believe, is better.

There are many more cases where LT cannot detect the proper grammar. Also, I am on premium plan with ''Enhanced grammar, punctuation and style checking''. The only reason I use it because it helps me with additional language. Overall, it is decent for the job, but if you speak only English, then I don't recommend it.

ne fonctionne pas sur odysee

Es wäre schon wenn das System noch was besser mit meinem FireFox arbeitet. Das heist den Text den ich schreiben will besser über das Adon nutzen zu können. Und das Kontrollieren eines Dokument über Browser von Texten könnte bei dem Preis auch was besser klappen. Alle weiteren Anwendungen wird die Software mir zu teuer. Ich bezahle schon eine Jahresgebühr und die ist teuer genug um das Unternehmen und die Idee zu Finanzieren für Open-Source

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.

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.

É bom... mas poderia ter uma opção de ligar e desligar geral de forma mais simples, para só fazer uma revisão no final.
Em alguns momentos é incrível, sugeriu por exemplo, "Vamos criar" por "Criaremos" ou "Budget" por "Orçamento" ou "como um todo" por "na totalidade"... Em outros não entendo, por exemplo, não percebe qualquer erro nesta frase: "A rais da árvore esta podre"

В русском регулярно предлагает ошибочные исправления. Нужна какая-нибудь кнопка, чтобы пользователь мог на это указать. Особенно под орфографию стоило бы прикрутить какой-нибудь официальный словарь.
