- 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.
