Identify AI-generated text with these Chat GPT detectors

Last Updated on

If you are a frequent user of OpenAI’s language model, you may be wondering what Chat GPT detectors are out there. In this article, we will dive into the current technology available that can detect AI-generated texts.

For those who aren’t familiar, Chat GPT is a revolutionary online AI model, which was made free to the public near the end of last year. The AI bot has been making headlines for its human-like responses and ability to do pretty much any task.

Many users have been taking advantage of what this model can do. For example, using the bot for essay writing, completing coding tasks, and generating creative content.

In recent news, media company, Buzzfeed has announced they will be using the technology behind Chat GPT to create written content for their site. This is a major step for AI. There are already mounting concerns about AI models, like Chat GPT, replacing human writers, and to our dismay, it is already happening!

A major issue with widely available AI models, like Chat GPT, is that many students are no longer writing their own assignments.

To combat this, anti-cheating software companies and AI detection businesses are playing a game of cat and mouse trying to catch up with Chat GPT’s capabilities.

Some have already caught up and we will be outlining these AI detectors below. So, what are we waiting for? Let’s jump right in.


GPTZero is a tool developed by Edward Tian, a 22-year-old from Princeton University. The app claims to detect texts created by Chat GPT and as of late has had a 98% success rate. The pilot version of GPTZero is currently available for free on their website.

The way the tool works is by measuring two attributes of the generated text: Perplexity and burstiness. In Tian’s words, “perplexity is a measurement of randomness”. The higher the perplexity or the more random the text is, the higher the chance a human wrote it.

Burstiness relates to how intricate the sentences are. According to Tian, humans typically write using varied sentence lengths to create impact. Whereas, AI models tend to write more consistently. By looking at both perplexity and burstiness, Tian has managed to create a very reliable Chat GPT detector.

Corrector App

Corrector App’s AI Content Detector is another free online tool that is supposedly capable of identifying Chat GPT-generated texts. According to the website, the tool is specifically designed to detect texts that have been created with some help from a GPT-3 model.

To check a piece of work, you can simply paste up to 300 words at a time and run a full audit over the passage. The tool works by running ‘syntax’ and ‘semantics’ analysis on the submission. It then outputs a “fake” percentage score indicating the likelihood of the text being GPT-generated.

OpenAI’s AI Text Classifier

In recent news, OpenAI has released their version of an AI detector named AI Text Classifier. The beta version of the tool is currently free to use from their website.

According to OpenAI, the detector has various limitations but the company believes it may be useful for the public. The service works by measuring the likelihood of text being AI-generated. Bear in mind, the tool is not 100% accurate so there is a risk that your passage could be incorrectly identified.

What is a ChatGPT Detector?

A ChatGPT detector is a piece of software which works to identify text which has been generated by Chat GPT. They work in various ways, and are not 100% accurate. However, they are beginning to form useful tools in the efforts against AI-assisted cheating and fraud.

Final Thoughts

So, those were a couple of Chat GPT detectors currently on the market. As time passes, it is highly likely that GPT detection technology will become much more sophisticated. Making it merely impossible to get away with AI-generated essays and assignments.

It is important to note that in the future OpenAI has already announced that they will be creating watermarks to attach to Chat GPT’s responses. This will indicate when the text was generated using their model, making Chat GPT detection much easier in the future.
