What are AI Watermarks?

AI watermarks are invisible markers embedded in AI-generated text to identify its artificial origin. These sophisticated tracking mechanisms use various techniques to mark content without affecting its visual appearance. Our tool helps you detect and remove these hidden characters for legitimate quality assurance purposes.
