Hands-on notes from our editorial team.
✅ Our Test
We went to the GPTZero site and noticed the tool offers 10K free credits per month after signing up. Without signing up, you can still test the tool directly on the homepage, but it limits you to7 free trials per day. After signing up, however, you receive33 free trials per day. We signed up using Google for convenience.
On the dashboard, we added an AI-generated text created with ChatGPT and clicked the "Scan" button. The tool successfully detected it as AI-generated content.

We repeated the process with another piece of AI-generated text, and the tool accurately identified it again as AI-generated.
Next, we added a human-generated text and scanned it. GPTZero successfully identified it as human-written, confirming its accuracy. We then tested another shorter human-generated article. Once again, GPTZero detected it as human-written, passing our test with consistent results.
The tool worked as expected and accurately differentiated between AI-generated and human-written texts. It successfully passed all our tests.
