Best Free ChatGPT AI Detector

In recent years, Artificial Intelligence (AI) has become an integral part of our daily lives. AI-powered tools and services are increasingly being utilized to solve complex problems, streamline business operations, and enhance our overall quality of life. One such tool is ChatGPT, an advanced AI language model developed by OpenAI. However, as AI technology becomes more prevalent, there is also a growing need for AI detection tools that can help us identify and protect ourselves from malicious AI applications. In this article, we will explore the best free ChatGPT AI detector tools that can help you stay safe in the digital world.

What is an AI Detector?

Before delving into the list of ChatGPT-generated AI detectors, let’s clarify what an AI detector is. An AI detector is a software tool that employs algorithms to detect the presence of AI-generated text. These detectors analyze text patterns and identify characteristics that are unique to AI-generated content. AI detectors are essential for tasks such as content moderation, spam detection, and preventing the spread of misinformation.

Understanding AI Detection

AI detection tools are designed to identify and analyze the behavior of AI applications. These tools employ various techniques such as machine learning algorithms, behavioral analysis, and pattern recognition to detect and classify different types of AI applications. AI detection tools can help identify both benign and malicious AI applications. Benign AI applications are designed to perform useful tasks, such as chatbots, speech recognition systems, and recommendation engines. In contrast, malicious AI applications are designed to cause harm, steal sensitive data, or disrupt critical systems.

How to Use ChatGPT Written AI Detectors

Using ChatGPT-written AI detectors is quite straightforward. Most AI detectors are web-based tools that require you to paste the text you want to analyze. Once you have entered the text, the AI detector will analyze it and provide a report on whether the text is AI-generated or not. Some AI detectors are also available as APIs that can be integrated into your own software or platform.

Best Free ChatGPT AI Detector Tools

There are several free ChatGPT AI detector tools available that can help you identify and protect yourself from malicious AI applications. Let’s take a look at some of the best options:

OpenAI GPT-3 Detector

The OpenAI GPT-3 Detector is a free tool developed by OpenAI that utilizes machine learning algorithms to detect and classify different types of AI applications. This tool can detect both benign and malicious AI applications and provides a comprehensive report on its findings. OpenAI GPT-3 Detector is easy to use and can be accessed through the OpenAI website.

OpenAI Text Classifier

The OpenAI Text Classifier is a finely tuned GPT model developed by the creators of ChatGPT. While it can predict the likelihood that the entered text is written using AI, it is not entirely reliable yet and should not be relied upon as the sole tool for catching AI-written text.


The Copyleaks AI detector is an API that can be used to create other detection tools. It supports multiple languages and can be employed to check for plagiarism in AI-generated content across all supported languages. Copyleaks AI Content Detector boasts an impressive accuracy rate of 99.12% and supports multiple languages, including French, Spanish, and German. It can even detect content generated using upcoming models like GPT4.

GPT Radar

Utilizing the same GPT-3 model as ChatGPT, GPT Radar is a highly accurate AI detector that is ideal for commercial applications. It can be used to ensure compliance with Google ranking guidelines and safeguard your brand's image. Although it is not entirely free, it is affordable at $0.02 per credit, with each credit allowing you to scan 125 words. By signing up, you will receive 2000 free credits, which is sufficient to scan a substantial amount of text.

Content At Scale

Content At Scale utilizes three levels of AI, including Natural Language Processing (NLP), semantic analysis algorithms, and Search Engine Results Page (SERP) parsing capabilities, to provide the most accurate results. They claim to possess the most up-to-date AI detection tools, enabling them to accurately assess the most recent large language models. Apart from detecting AI-generated content, Content At Scale also offers AI-powered content creation services. They claim to generate over 20 long-form texts for content marketers that can bypass all AI detectors, showcasing two sides of the same coin.


Writer's AI Detection software is the most straightforward AI detector, with a character limit of 1500 characters per search (approximately 300 words). Unfortunately, there is no option to remove the character limit, and the premium version only increases the monthly word limit to 250,000 words, compared to the free limit of 100,000 words.

GPT Zero

Next up is GPT Zero, a web app created by a 22-year-old college student named Edward Tian. It employs two factors, Perplexity and Burstiness, to determine if the input is AI-generated. The higher the complexity of the text, the more likely it was written by a human.

GPT Zero is another AI content detector that utilizes the same GPT-3 large language model. It claims to have over a million users, including major publishing houses such as the Wall Street Journal and the BBC. With continuous updates from developers, GPT Zero is always at the forefront of AI detection.


Corrector is a completely free AI detector that allows you to scan content by pasting it into the website or uploading a document. This enables you to identify fraudulent content before publishing it on your website. Corrector also promises to support and detect GPT-4 content in the future.

GPT-2 Output Detector

The GPT-2 Output Detector by OpenAI is another free tool available through HuggingFace. It rates text on a scale of 0 to 100, with higher scores indicating AI-generated text. This specific tool is designed to detect content generated by the GPT-2 language model. GPT-2 is known for producing highly convincing but potentially plagiarized content. The GPT-2 Output Detector employs advanced algorithms to identify any content that has been generated by GPT-2 and provides information on the likelihood of plagiarism. This tool is crucial for ensuring that any content generated by GPT-2 is properly attributed and that the original authors receive due credit.


Copyscape is a plagiarism checker that scans web pages to find matching text and identifies the source of the copied content. Copyscape is a popular tool used by writers, publishers, and website owners to check for plagiarism in their written content. It compares a given text to a vast database of existing content on the web to identify any similarities. Copyscape is easy to use and can quickly identify if any content has been copied from other sources. It is an essential tool for maintaining the originality of written content and ensuring that proper credit is given to the original authors.
