Is Copyleaks an reliable AI detector?
I am in the same pickle now. Either Copyleaks is ridiculously accurate, or the other ones are extremely inaccurate. How did it end for you? More on reddit.com

ChatGPT and Copyleaks
Many of the AI-detecting systems use machine learning themselves. If that's the case, the results are not entirely deterministic, especially if passed through different UIs/APIs that might quietly mangle the input. And if you're getting different results between text and PDF input, it might also be the case that the PDFs are not as machine readable as you expect. More on reddit.com

Does the Copyleaks AI Detector flag writing tools like Grammarly as AI content?

Not all writing tool features are flagged. Grammarly’s AI-based rewriting features may trigger detection, while basic grammar and spell-check functions typically do not.

The AI Detector is designed to distinguish between minor edits and generative rewriting, helping ensure fair and accurate analysis.

May 25, 2023 - Copyleak read mine at 0% AI. My grade from Turnitin flagged it at 12%. Continue this thread ... Cooykeaks is a crappy AI detector. I wrote my own word paper and tells me 100%AI. Broke down in paragraphs and rechecked. Pretty much all human. It does not believe in people saying the same thing.

r/SEO on Reddit: Is CopyLeaks a reliable AI content detector?
September 13, 2024 -

I make all my content writers ensure their content passes AI detection using CopyLeaks... becausse I know all of them will try to take advantage of AI to write the bulk of their content...

Now, these guys are now all telling me that the tool sucks and that even though they rewrite entire paragraphs, their content is still flagged as AI content by this tool.

What do you guys think? Should I side with my writers and ditch this tool or should I side with CopyLeaks? :)
