Polygraf AI has officially become an essential part of the content writing workflow. Its ability to accurately detect whether content is written by humans or AI is impressive. Other useful features include the copyright detector, writing analysis, cognitive flow index, and the AI humanizer. I recommend Polygraf AI to marketers, writers, and academic professionals alike!

This is so cool! It helps me write and rewrite everything that is AI generated and also helps me to see on LinkedIn or other sources who is using AI generated content for their posts. So many other tools available and I think its worth checking out
