Perplexity did this to your response. I'm not sure that correcting grammar and changing one word makes it sound wooden.
"I understand this if you’re not a native speaker, but if you are, it will generally make you sound a bit unnatural."
"I understand this if you’re not a native speaker, but if you are, it will generally make you sound a bit unnatural."
Switching "wooden" for "a bit unnatural" also does a disservice: "wooden" describes a specific quality of deviance.
Over-all, I would definitely consider the revision stiffer and more reserved than the original.
