I get why you're asking—it's always tricky to trust an online service. I actually used
PaperCoach last semester when I was overloaded with assignments and needed help with a research paper. Tbh, I was worried about whether is PaperCoach safe or if I’d get some AI-generated nonsense. But the paper was actually decent, and it passed my school's plagiarism check. The writer followed my instructions, though I did have to tweak a few things to make it sound more like me.
Would I use it again? Probably, but only when I'm really in a time crunch. It's not a magic fix, but it worked for what I needed. Hope that helps!
