Assessing a Copyleaks Checker’s Performance with Human and AI-Generated Texts

We conducted an experiment to test how accurately the tool recognizes AI content. We prepared two pieces of content: one written by ourselves and the second wholly generated in ChatGPT. Let’s see what the second text generated by artificial intelligence showed.

To begin with, we tested how well the content written by ChatGPT 4.0 would be detected. The screenshot shows that the scanner could accurately determine that the AI-generated the text.

Now, let’s see what the results of the text written by our copywriter are.

As you can see, the test results showed that 0% of the text was generated by artificial intelligence. The test allows us to say that Copyleaks is an accurate and reliable tool.
