Is using apps like Wortune, Grammarly and Quillbot considered … – Reddit

I guess it depends on how you use them. I think Grammarly is fine, it just checks your grammar afaik and rephrases things to maintain a tone, i.e. refinement. Quillbot and Wordtune, I personally avoid them. They just paraphrase whatever you give them, so they pretty much write that bit for you unless you only use it to paraphrase something to understand it better.
