I tried that in another topic. Conclusion: I'm a bot

Since I'm obviously human, the detection is unreliable.
You didn't say what was the percentage showing text was AI generated on all 3 websites...
The site I tested before labeled me as
81% fake.
How do you think we are detecting plagiarized text by other members?
We certainly don't have super powers, and I was always using two website to detect source and PERCENTAGE of plagiarism... it worked well most of the times.
I always use an exact match on them, or manually find word spinning. I've never used a "plagiarism detector" for it.
