Today, I’ll review ContentDetector.AI and test it with different things to find out how accurately it works. Before I start reviewing, let’s find out the review process.

Process of Reviewing 

I thoroughly tested the ContentDetector.AI to see how well it could tell whether the content was written by a human or generated by AI:

Step 1: Initial Evaluation

I began the review process by comparing human-written and AI-generated content to see if this AI checker could tell the difference.

Step 2: Precision and Reliability Test

In this step, I compared the accuracy of this tool to that of a human-written blog and an AI-generated piece. 

Step 3: Experimenting with Strategies

Finally, I tried various tricks to see if this AI detector could show AI-generated content as human-written. 

Checking How Well ContentDetector.AI Works

This AI content checker is very simple and easy to use. You have to just open the website, copy your text, paste it into the text box, and click “Analyze.”

Now, let’s check the accuracy of ContentDetector.AI. I simply asked ChatGPT to generate a paragraph on tea. 

ChatGPT instantly provided me with a paragraph of 87 words on this topic. Let’s see if this tool can detect its AI similarity.

I opened the tool and pasted my generated paragraph in the text box to check for AI plagiarism. It gives the probability of 66.67% of the text, showing that the content may have AI, and also highlights it in the text.

Now that I’ve tested this tool with AI content, it’s time for us to check what it will do with human-written content.

I wrote a paragraph on the same topic and inserted it into the tool. Here’s what it showed:

This time, ContentDetector.AI gives me a probability of 42.86% and shows that the text is likely human-written. It means the tool works fine for finding AI similarity within content.
