AI vs AI: How Do AI Tools Detect AI-Generated Content?

Video by KNOW (KnowNow).

AI is everywhere these days, even in education! While AI tools like ChatGPT can be a great help, teachers and schools are now using their own AI-powered tools to check if students rely too much on artificial intelligence. But how do these tools work?

AI detection tools analyze the text students submit. They're like supercharged detectives, searching for clues that indicate whether something was written by a human or an AI model.

One way these tools work is by comparing writing styles. Human writing often has quirks—like inconsistent phrasing or surprising ideas. AI-generated text, on the other hand, tends to be polished, predictable, and even a little too logical.

Detection tools like Turnitin use advanced algorithms to identify patterns in text. They’re trained on massive datasets of AI-generated content, which helps them recognize common traits, like repetitive phrases or overly formal tone.

These tools assign a score based on how likely the text is AI-generated. For example, Originality.AI is designed specifically to detect content written by tools like ChatGPT, giving educators a clear idea of what might be AI-generated.

But it’s not just about patterns. Some tools, like OpenAI’s AI Classifier, also analyze deeper factors, like changes in writing style. If your essay suddenly sounds way more sophisticated than your usual work, that could raise a red flag.

Here’s another trick: some AI tools embed invisible watermarks in the text. OpenAI, for example, has experimented with these markers, making it easier for detection tools to identify AI-generated content.

But let’s be real—no tool is perfect. False positives can happen, and clever students might tweak AI-generated content to fool the system. That’s why these tools, like Turnitin, Originality.AI, and OpenAI’s AI Classifier, are just one part of the process. Teachers still use their own judgment to ensure fairness.

In the end, AI detection tools are a step toward balancing technology and creativity in education. So, whether you’re writing on your own or using AI to help, remember: originality always stands out!
