What Is the Best ChatGPT Detector Tool? Top 6 AI Text Detectors

As the frontier of artificial intelligence continues to expand, the line between human and AI-generated content is becoming increasingly blurred.

The rise of sophisticated AI models like ChatGPT has made it challenging to distinguish between a human’s creative prowess and an AI’s programmed proficiency.

But fear not, for there are tools designed to help you navigate this new landscape. From plagiarism detection to AI content identification, these tools are your allies in the quest for authenticity.

Here, we will explore some of the best ChatGPT detector tools available, their features, and how they can help you ensure the originality of your content. Let’s dive in and unravel the mystery of AI-generated content.

Want to Avoid AI Detection? Check This: How to Humanize AI Text

1. CopyLeaks: The Best of Them All

The first tool on our list is CopyLeaks, a versatile AI detection tool that offers both free and paid versions. This tool is particularly useful for detecting AI-generated content and conducting plagiarism tests.

When you paste a text into CopyLeaks, it processes the content and highlights the parts written by AI in red. For the free version, you can check up to 3-4 pages for free in a day. In the paid version, you can get a detailed report showing where the text is taken from, making it easier to identify copied or rewritten content.

CopyLeaks’ pricing starts at $9.16 per month, offering 1200 pages up to 300,000 words yearly. For monthly users, it costs $10.99 for 25,000 words. Although the pricing might seem a bit steep, the tool’s dual functionality of AI content detection and plagiarism testing makes it worth the investment.

2. Originality.ai: Versatile ChatGPT Detection Tool

Originality.ai is another popular AI detection tool. Unlike CopyLeaks, it doesn’t offer a free version. However, it provides a value-for-money option with a $20 plan that allows you to scan up to 200,000 words. The best part is that the credits do not expire, meaning you can use them whenever you need to.

The interface of Originality.ai is user-friendly, and it highlights the AI-generated content in red. However, it’s worth noting that the tool sometimes provides “False Positive” results, detecting human-written articles as AI-generated content. The developers are working on a feature to adjust the detection strictness, which will be launched soon.

3. Turnitin: A Reliable Plagiarism and AI Writing Detection Tool

Turnitin, a renowned plagiarism detection software, has recently incorporated live AI-writing detection features. This new addition is designed to identify the use of AI writing tools, including ChatGPT, with an impressive 98% confidence level.

The development of Turnitin’s AI detection feature has been a meticulous process, focusing on the detection of the content generated by ChatGPT and other AI writing tools. The development team has been continuously refining this feature to ensure its effectiveness and accuracy.

Turnitin’s AI detector boasts an overall accuracy of 98%, with false positives occurring less than 1% of the time. This high level of accuracy is a testament to the nearly two years of development that went into this feature before its release.

The team behind Turnitin’s new features has also discussed the implications of ChatGPT on the future of writing instruction and literacy outcomes. They recognize the evolving needs of Turnitin’s education users to access reliable AI detection tools, especially in an era where AI-generated content is becoming increasingly common.

Turnitin’s tool, known as Originality, is claimed to detect 97 percent of writings generated by ChatGPT and GPT-3. The company also asserts that its tool has a very low false positive rate, further solidifying its reliability.

4. AI Detector Pro: A Comprehensive AI Detection Tool

AI Detector Pro is a robust tool that primarily operates on a paid model, but it does offer three free reports each month. This tool is especially beneficial for those who regularly deal with large volumes of content and need to ensure its authenticity. The paid version, starting from $14 per month, provides 100 reports with no word limit, making it a cost-effective solution for businesses and individuals alike.

One of the standout features of AI Detector Pro is its ability to identify words and phrases commonly used by AI. This feature gives users a rough idea of whether the content is AI-generated, which can be particularly useful when hiring content writers or publishing AI content on blogs. By identifying these AI-generated phrases, users can make necessary modifications to the content, adding humor and specific details to make it appear more human-like and less detectable by AI.

AI Detector Pro is not just about detection; it’s about understanding the nuances of AI-generated content. It identifies phrases like “when,” “approach,” and “scheduled,” which are often used by AI. It also detects the use of conclusions in every part of the article, a common characteristic of AI-written content. Phrases like “Often Touted,” “Not to mention,” “It also increases the risk,” “Either Way,” and “Additionally,” are also commonly used by AI, and AI Detector Pro can highlight these for you.

The tool’s interface is user-friendly, allowing you to open an article and immediately see the words used by AI. This feature, combined with the tool’s comprehensive reporting and unlimited word count, makes AI Detector Pro a valuable asset for anyone needing to distinguish between human and AI-generated content.

5. GPTZero: A Cost-Effective Solution for ChatGPT Detection

GPTZero stands out as a free tool that can efficiently detect ChatGPT content. While it may not be as accurate as some of the paid tools, it does a commendable job of highlighting terms written by AI. This makes it a good option for those looking for a cost-effective solution to AI content detection.

GPTZero’s strength lies in its simplicity and effectiveness. When you input a text, it processes the content and highlights the terms written by AI. Although the tool is not 100% accurate, it provides a good starting point for identifying potential AI-generated content.

However, it’s important to note that no tool is perfect, and GPTZero is no exception. While it does a decent job, it’s always a good idea to use multiple tools and your judgment when determining whether a piece of content is AI-generated or not.

6. OpenAI Text Classifier: A Free Tool with Limitations

OpenAI, the creator of ChatGPT, has developed a free tool known as the OpenAI AI Text Classifier. This tool is designed to detect AI-generated text from a variety of sources, including ChatGPT. The classifier is essentially a fine-tuned GPT model that predicts the likelihood of a piece of text being AI-generated.

To use the OpenAI AI Text Classifier, users simply copy and paste their text—ideally a minimum of 1,000 characters—into the classifier. The tool then predicts whether the text was likely generated by an AI. It’s important to note that this tool was trained using text generated from 34 models from five organizations that deploy language models, including OpenAI itself.

However, despite its potential utility, the OpenAI AI Text Classifier has its limitations. It is not fully reliable and should not be used as the sole decision-making tool for detecting AI-generated content. According to a report by The Verge, OpenAI’s classifier labeled AI-written text as “likely AI-written” only 26 percent of the time and gave false AI detections 9 percent of the time.

Based on the information provided, Turnitin’s Originality feature is one of the most accurate GPT detectors. It claims to detect 97 percent of writings generated by ChatGPT and GPT-3, with an overall accuracy of 98% and a false positive rate of less than 1%. However, I like Copyleaks more as it is free and sufficient for my needs.

How reliable are ChatGPT detectors?

The reliability of ChatGPT detectors varies depending on the specific tool. Some tools, like Turnitin’s Originality feature and AI Detector Pro, have high accuracy rates and low false positive rates, making them quite reliable. However, other tools, like the OpenAI Text Classifier, have been reported to sometimes struggle with accuracy. Therefore, it’s recommended to use multiple tools and your judgment when determining whether a piece of content is AI-generated or not.
