Here you might be right because I mostly use translator to understand post well.
Because English is not my native language and when I write post I also check it with translator. If there is any mistake I simply correct it myself. So because of this you can say that my posts are being flagged as AI.
By the way I apologize. I made mistake in understanding your words again. As for GPTzero I do not even know about that tool. You are using it so you know better.
No worries. I didn't claim that you're using AI, but that your posts were suspicious. If it's not a direct copy paste or it's obvious. Your post weren't the obvious, usual AI we've seen, but something was off. If you're using a translator, it could explain why they're flagged. However, GPTZero is generally safe and accurate, Sapling.ai for instance isn't.
You could use Quillbot or a similar platform, but only to correct some of your mistakes, not rewrite your post. Anyway, sorry for the inconvenience if you initially considered I was accusing you, but something did indeed look off. I'm okay unless some other experienced member wants to mention something else.
