How Do AI Content Detection Tools Work?

It is all about machine learning. These programs are trained on vast amounts of datasets, allowing AI content detector tools to recognize patterns and make predictions based on that data. Using that pattern, then, these tools determine if a human created the content.

Additionally, AI can quickly assess all the information on the internet for a certain subject topic. This enables it to determine if the content created is real.

How Accurate are AI Content Detection Tools?

Many AI detector tools claim that they are quite accurate in detecting AI content. They use cutting-edge algorithms to detect texts that might be AI generated. And they do a shockingly decent job at it too!

But let us not get carried away just yet – these tools are not infallible. There is always the possibility that some AI Content may slip through the cracks (after all, AI isn’t perfect…yet).

So, while we can certainly rely on them to flag most automated Content, we should still exercise caution and use our own human judgment as well.

Comparison of Different AI Content Detection Tools

Here’s a comparison of different AI content detection tools based on their accuracy.

We used ChatGPT to create a 300-word blog post and ran it through each of the AI Detector tools listed above.

As seen in the comparison table, each AI detector displays the percentage of AI-generated text. Based on the aforementioned results, Copyleaks appears to be stricter and difficult to bypass AI detection.

Although GLTR does not provide a score for AI plagiarism, when we evaluated the blog on GLTR, we noticed that about 90% of the material was flagged as suspicious (AI written).
