Typed a few sentences, it corrected a few errors, then told me I needed to pay for premium to detect any further errors.

Premium might be worth it for some people, but for me it's not that serious. I can live with the occasional grammar mistake.

Não está funcionando no Firefox. Utilizo essa extensão em todos os navegadores que uso a anos, é a melhor.
Mas infelizmente no Firefox ela não funciona em nenhum campo ou documento de texto.

Not much use, doesn't detect grammar issues and has very limited options for guessing what you were trying to type. Turned it off almost immediately.

Does not work

This extension is just as useless as Grammarly.

Suddenly stopped working on FF but continues to work on Chromium based browsers.

This addon DOES NOT autocorrect words as you type.

No good addon. Look elsewhere guys

It's very helpful if your time is worthless: it shuts down more and more of it's most useful feature for a paid version... even firefox default is catching up

Except for the constant ads that tell me I would need to pay for an upgrade just to see other errors, I would have rated it higher. I am almost ready to report it for abuse.

Das Tool findet mehr Rechtschreibfehler als Microsoft Office 365. Respekt! Aber die Geschwindigkeit des Tools ist ein wahre Katastrophe. Ein Dokument über 1.000 Seiten prüft es abschnittsweise. So weit, so gut. Aber wenn eine Prüfung 15 Minuten dauert, und das immer wieder, dann ist es untauglich.
Ich bereue den Kauf zutiefst!

Работало хорошо, но теперь оно доступно только платным пользователям

Japanese version is completely useless lmao

Ludicrously buggy. Often scrambles my text instead of applying its corrections. Also breaks some dialog boxes so you can't enter any text.

Suddenly decided to switch to a paid model, without anything even resembling a free tier.

Big checkmark obstacles view of input field, forcing to write without seeing. Could be shifted somewhere, or, better, removed completely. Whatsapp, Telegram, any on-liner input fields have this flaw.

Sendet alle eingegebenen Texte wie beschrieben nach Hause.

Danke dass dies immerhin deutlich ersichtlich ist.

I have used this add-on several times, only to find that #1) It is the worst spell and grammar checker ever, and often highlights words and grammar that are correct. And #2) It significantly slows down my typing and browser. As soon as I removed it, my typing and browser speed was fine. I would give it NO stars if I could. /// In response to the Developer. It affected all websites I use on Firefox. I've never had issues before, and when I removed your app, the slowdown stopped. As for bad corrections, I no longer use the app, so I do not have screenshots and wouldn't know how to post them here anyway, because there is no way to post photos. Update: 4.25.21 I am going to give it a try again and see what happens. I removed some other add-ons and maybe they were the problem. Will update soon!
