OpenAI’s ChatGPT has taken the world by storm. Language models built into the service are so flawless it becomes challenging to determine whether it’s a human-generated text or machine-generated text, given appropriate prompts are fed into it.

So for educational institutions and media channels, it becomes a concern if AI-generated text is used all the time. People are concerned that Google will detect AI content and push their rankings down even with websites.

Luckily there are a few ChatGPT detector tools that can help prevent this. These are imperfect, but they do get the job done for detecting AI-generated text within minutes.

And in this article, we will look into some AI detection tools that anyone can use to detect AI content. We will also understand how reliable and accurate these tools can be.

Free Chat GPT Detector

What is the Chat GPT detector?

Chat GPT detector is a machine learning model detecting tool that is specifically trained to pick up natural language outputs that could be generated by some AI tool like Chat GPT. These detectors are used by educational institutes a lot to ensure that the students are not submitting AI-generated reports or assignments to the faculty. 

Besides educational institutes, any other field that requires AI-free content also uses this tool extensively. These detectors are not 100% accurate. However, they are proving their might gradually against AI-assisted cheating and fraud.

Several GPT detectors will appear if you search for one on Google. Which are the best ones among the whole list that shows? Let’s take a look at it and find out.

Top 7 Free Chat GPT Detectors In 2023 developers claim that their tool can detect AI content with 96% accuracy, tested on a data set of 1200 samples. It can detect all AI content generators, such as GPT-4, Bard, and more.

This tool explicitly separates human-generated and AI-generated content by highlighting sections with different colors. This is not free at all, though. One credit gets you one scan, and one credit costs $0.01.

This is one of most widely used ChatGPT detector tool right now to prevent or detect instances when writers, or students use GPT to write up their assignments, essays, or content.


GPTZero is a tool developed by a 22-year-old student from Princeton university, and he claims that the tool has an accuracy of 98% when it comes to detecting Artifical Intelligence based content. His model is based on burstiness and perplexity. Humans write text with a more random pattern than AI, and that is what perplexity is all about. 

Furthermore, burstiness is related to sentence lengths. Humans use varied lengths, whereas AI generally follows similar lengths for sentences.


Corrector App has an AI deception tool explicitly developed for ChatGPT 3 model creations. Their primary tool is a grammar correction tool that works flawlessly, but their ChatGPT detector tool is no slouch either.

Premium version lets you check any article with no specific word limit. But ib the free version, you can only insert 300 words and check the content for any AI signatures.


This works with OpenAI GPT-3 to detect any text an AI could generate. GPTRadar is designed specifically to detect GPT based content. It might now work that well with Bard, and other content tools. But as a ChatGPT detector tool, this works surprisingly well.

You can run a few initial tests for free. But following that, you will have to buy and spend credits for additional scans. combines four different detection models that can calculate texts’ entropy, correlation, and perplexity to determine whether an AI or human writes it. It can detect articles created with all GPT algorithms, ChatGPT, GPT-3.5, and GPT-4.

This tool is specifically developed to help content creators, editors or writers, to check whether the content they plan to publish on their site has any AI signature or not. Content creation is all about originality, and this ChatGPT detector tool allows user to ensure it.

Writer’s AI content detector

This is a free tool where a user can either put in the content directly, or provide a link for it. Once the link or content is provided, the tool will start analyzing it and give it a score out of 100. A higher score will indicate that the content is original with minimal AI intervention. While a lower score close to 1 will indicate that the content is filled with AI generated content.

Content at Scale

Content at Scale is another free alternative that can work as a ChatGPT detector tool for all kinds of users. You can either put in the content itself or provide a link for it. The tool will start ranking the piece with a score out of 100. A 100 score will indicate that 100% of the content is AI generated. While a lower score will indicate more human generated content.

Are ChatGPT detectors accurate?

ChatGPT detectors are only partially accurate. They only give rough estimates and sometimes even detect human-written text as AI-generated. Some tools claim a 95 or 96 percent accuracy, but these tests were conducted in a selective environment with very little sample space. 

So the accuracy of any ChatGPT detector is for now unpredictable. As more and more content comes in for a check, and development is further put into the tools, we will keep seeing improvement in terms of accuracy in the future.

Do GPT detectors work?

Yes, ChatGPT detectors work, but they do not operate flawlessly. They can be a hit or miss at times.

There have been instances where some human generated sentences are detected as AI content by some tool. But the sentences that are indeed written with Artifical Intelligence are detected correctly almost all the time.


With every passing day, the algorithms on the AI content detectors will keep improving, resulting in accurate results in every way possible. But we might not need these detectors in the future. OpenAI has announced that they will add a watermark to the content generated by ChatGPI. So there would be no cheating in terms homework and assignment submissions being filled with AI-generated content.
