- Cant say it's anything less than perfect when typing long sentences and correcting the mistakes you made. Really helps keep the flow of what you are writing, rather than having to correct your mistake by going back and breaking the whole flow.

- I revisited that extension today after several years of using LanguageTool, because that latter is becoming for paying Premium only. Sadly, there is something wrong with this extension here. When it is activated, my browser becomes basically unresponsive. When desativated, my browser is back to normal. I did try 3 times that same processus, and every time the same result. So I can't rated as good, for it freezes my browser.

- I am enjoying the help quill Bot which is helping me with my management textbook. One problem I am finding is the overwhelming use of adjectives such as the work meticulous and other over exaggeration of adjectives. Perhaps an added benefit would be to have a thesaurus available instead of some of the frivolous click ons. Otherwise, a great start to AI and my writing skills.

- It is formal in style while I am colloquial. But the comas don't matter and the voices can stand help. Plus I tend to drop endings on words. It definitely has made my writing better. I told my 8th grade english teacher I would one day have a machine to do my spelling and grammar. It is here and I am delighted. Surprised it is not helping me with this review.

- "Quillbot is a fantastic writing companion! AI tools are a huge help when it comes to polishing our thoughts, but at the end of the day, the ideas belong to us. I’d love to see a feature that explains the 'why' behind the edits. Understanding why a specific preposition or verb was swapped would not only improve our text but also our language skills. Thank you, Quillbot!"

- The extension is great, that always be correcting my writings from various platforms on chrome, it also corrected my french writings whenever I had something to write in french, which I didn't know at first, but is a wonderful useful platform, not complicating things, just straight forword.

- Also a LanguageTool refugee, it seems to be a good drop-in replacement so far. Except for one thing, it keeps nagging you with advanced recommendations that are only available with Premium. It's fair that advanced recommendations are behind a paywall and that users are told about it, once. The issue is that they keep coming back even after ignoring them, and it seems there is no setting to turn them off. So it's basically showing you ads all the time. Please provide a button or a setting to turn these ads off permanently. If this does not happen, I will move to an ad-free alternative as soon as they support more websites, such as the open-source, privacy-respecting Harper.

- LanguageTool refugee here, QuillBot is a great alternative from what I can tell so far. It's funny how it doesn't work here in the Webstore tho but I'm assuming there is a valid reason for that. Let's hope you guys will keep the basic version free to use in the future :)
