Rewriting Essay Service, does it actually improve your paper or make it worse?

I wrote my essay myself, but it doesn’t sound strong enough. I’m thinking about trying a rewriting essay service just to polish it. Not looking for someone to cheat for me. Just better wording and structure.

Has anyone used a college essay writer for editing only? Or maybe a rewrite essay AI tool?

Does essay rewriting really help, or does it just make everything sound generic?
