I do a LOT of writing, a large amount of it as short essays, and commenting on YouTube and social media platforms. It is very important to me to compose texts using the best language grammar, spelling, punctuation, etc. I primarily write English text, but also German, Spanish, and French respectively. I also use a lot of Latin phrases, but being very new to this extension/app, I don't know if it is supported. I have read many reviews about this extension. So far, I've been using it on all my compositions, to the limit allowed in the free version. I just need to clean up, and check for errors, as I appreciate and consider any suggestions it makes. So far I love it. Any flaws I might have seen are quite petty, and I easily work around them. I consider myself able to command English, and language in general with well above average power. Nevertheless, this extension is already helping me improve. I give for stars, to allow room for well deserved improvements, which I KNOW are coming. Then I will upgrade to Premium. This is a fine App. IMO.
