Absolutely Terrible As an educator, I decided to use this tool to check my students work to see if it was legiamate. After checking every single paper in the class only 1 out of 55 students was not flagged for ai, so I went home to grade all these students a 0 and set up meetings with the board to punish these students... but at the last minute I decided to check some of my papers and they had said they were ai! What is this application? It is false! EDUCATORS, DO NOT WAIST YOUR TIME ON THIS!

Dear Copyleaks, Your AI Detector Is Absolutely Horrible. I can't believe how bad your AI detector is. It’s honestly the worst tool I’ve ever used. It flagged my own original work as AI-generated, which is ridiculous. Are you even testing your product properly? This is unacceptable and a waste of my time. If this is the best you can do, I don’t see the point of using your service. Fix this mess, or just stop calling it a tool altogether.

WHAT IS THIS? First, I spend time writing high-quality content by myself, and then I have to spend three times as much time just to see the "human" label in Copyleaks?! Even though the text was originally written by me! If this is an attempt to make money by forcing people to buy your subscription to see the mistakes, it's A SHAME! Just on the morning of November 19th, all my texts were 100% human, and the next day, suddenly, all of them were 100% AI-detected... HOW IS THIS EVEN POSSIBLE???
