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
Not found as was expected
Honestly, I was skeptical at first, but Polygraf has exceeded my expectations. It’s simple, reliable, and gives me peace of mind knowing my work is truly mine.
Polygraf is exactly what I was looking for. It helps me ensure that my essays are 100% authentic, and the real-time analysis is incredibly convenient. Highly recommend!
This extension is a must-have for anyone serious about keeping their writing clean. I love how it integrates seamlessly into my workflow—no more stress about accidental plagiarism!
Polygraf has been a game-changer for me! As a student, I need to make sure my work is original, and this tool gives me the confidence I need. Super easy to use, and the accuracy is spot on!
As someone who writes a lot of reports, Polygraf has become an essential tool. It’s so easy to check if my content is AI-free, and it helps me feel confident in my work.
Slick tool
I have been using this extension for over a month now and compared to other tools, I would say it is more accurate and gives you more in-depth details. E.g: it tells you what part of the text was humanized or if the content was deliberately altered to give it a human vibe with deception filter feature. Overall, I like how accurately it works and detects "on-the-go" while you surf on the web without the hustle of copying and pasting the text somewhere else.
