Do AI writing tools leave hidden watermarks in generated text?

I've recently come across discussions about AI writing tools potentially leaving hidden watermarks or invisible characters in generated content.

Is there any truth to this? Can Google or other platforms identify AI-generated content through hidden watermarks, even after the text has been edited or rewritten?

That has also occurred to me what i understand is that invisible characters and text watermarking through AI are two separate issues i am interested in knowing if these can be easily erased by ordinary editing, and how effective is the AI detection process
 
Leave a mark. It is traceable and detectable for that reason.
 
I've heard that too, but I think formatting the text in editor or pasting as text before rewriting solves the problem.

However, besides tiny codes or anything at all, AI-generated articles have patterns which humans can detect easily, so I think big tech companies like Google and others can do as well.

Some tools may add hidden characters, but there’s no universal AI watermark. Detection methods exist, though they aren’t always accurate.

Not all AI tools add hidden characters, and AI detectors aren’t always accurate.

yeah theyre different. invisible characters go away with a plain text paste. the real watermark is in the word choices, light edits dont remove it but a heavy rewrite mostly does
 
Some tools do. SynthID Text embeds statistical patterns in word choices, not invisible characters. Light edits may preserve them; heavy rewriting can weaken detection. It doesn’t identify text from every AI tool.
