there's this site called Paraphrasing Tool that, true to its name, does paraphrasing for you in just a couple of clicks.
link: paraphrasing-tool.com
how to use: key in in the first box the original statement. check "im not a robot" box then click "go"
like in this ss, "understudies" is an unnecessary replacement for "students" so i correct mo yan manually
Bonus:
