We begin with the release of a brand new AI plagiarism checker by OpenAI, the company that created ChatGPT. Known as the AI Text Classifier, this app is a well-crafted GPT model designed by the company. The classifier is responsible for determining the likelihood that a given text was written by a human or an AI.

The AI plagiarism checker has been trained using a set of data pairs, which includes inputs from both humans and AI. This makes it easy for the tool to identify plagiarized AI-generated text. The app is capable of processing all types of text and is accessible through the company’s website.

Although OpenAI has stated that the tool is not completely reliable yet and should not be solely relied upon to detect copied text, I conducted several tests by copying my own article from GeeksGyaan and several Wikipedia texts, and it was able to easily detect the human-written content. This is one of the best free AI plagiarism checkers available, but it requires a minimum input of 1,000 characters.

Plagibot is an AI-powered plagiarism checker that supports multiple file types, including Word files and PDFs, among others. The company has placed a strong emphasis on user-friendliness and designed the tool with an intuitive UI. Plagibot’s comprehensive database is continually updated, with the system scraping the web every hour for new information.

This AI-based text detection tool is highly effective at detecting plagiarism and identifying instances of copied content. However, during my usage, I did encounter some errors on the website. Fortunately, these issues were infrequent and did not significantly impact my experience.

It’s important to note that Plagibot is not a free tool, with the free tier limiting users to a monthly word count of 2,000. To access additional features and higher word limits, users must upgrade to a paid tier.

CopyScape

CopyScape Edited 1

One of the top AI plagiarism checkers, CopyScape operates differently from the other tools mentioned in this article. Rather than analyzing text inputs, CopyScape has the capability to scan entire web pages.

Essentially, CopyScape searches the internet for copies of your webpage and provides a list of web pages that have duplicated your content. Although primarily geared towards businesses to track whether their content has been plagiarized, the tool is accessible to individuals as well.

Using CopyScape is simple. You can just copy and paste the URL of a webpage into the tool, and it will take a minute or two to display Google-like results, with the copied content highlighted.

You can click on any of these results for detailed information, including exact word count and percentage of copied content. In general, the tool performs well in identifying AI-generated text.

GPTRadar

GPTRadar is a fittingly named AI plagiarism checker that uses GPT-3 technology to detect various types of text online and classify them as either human or AI-generated.

The tool is available on a simple website that may seem too basic at first glance, but it performs its job well. I put the tool to the test by pasting both my articles and Lorem Ipsum text into it, and it returned some intriguing results.

The tool concluded that the “Lorem Ipsum” text was most likely generated by a large AI model. It also provided a perplexity score, which reflects the model’s ability to predict words.

Additionally, the AI plagiarism checker split the text into chunks based on whether it was human or AI-generated. Furthermore, the tool provided a wealth of information, such as token probability and distribution.

Corrector App AI Content Detector

Corrector AI Content Detector 1024x469 1

The AI plagiarism detector offered by the Corrector app stands out from the rest of the apps listed here, as it supports all the GPT models, including the latest GPT 4 model. Additionally, this AI text detection tool uses contextual cues to identify similarities in text inputs. As with other AI plagiarism detectors, Corrector can be used by anyone for a variety of needs.

However, some users may find the results generated by the tool to be somewhat unclear. Instead of providing detailed metrics, Corrector utilizes a “Fake %” meter to output its results.

When pasting content into the app, users receive percentage results, but are limited to a maximum of 300 words per input. On the plus side, Corrector refers to itself as “The Sherlock Holmes of AI detectors,” which is a pretty cool moniker.

GPTZero

GPTZero is an AI-based plagiarism checker that comes highly recommended by many online users, and for good reason. This user-friendly tool is capable of analyzing text across multiple sources and employs statistical data to determine whether the text is generated by a human or machine. In addition, it utilizes an algorithm that examines other factors, such as perplexity and burstiness, in addition to originality.

My experience with GPTZero was generally positive, although there were a few moments of confusion. The tool was effective at distinguishing between human and AI-generated articles, although there were instances where it incorrectly identified original content as AI-written.

However, it’s important to note that these occurrences were infrequent. I found the tool’s metrics to be highly specific, which sets it apart from many other AI plagiarism checkers. Additionally, the tool is entirely free to use.

Copyleaks boasts a remarkable 99.12% accuracy rate in identifying whether content has been created by humans or AI using its AI-powered plagiarism detector. The tool also supports multiple languages, including French, Spanish, German, and more.

Copyleaks adopts a “fight fire with fire” approach, utilizing AI to detect AI-generated text. This allows the tool to evolve and remain effective against the newest AI chatbots, making it a highly capable tool. Copyleaks has even pledged support for ChatGPT 4 when it becomes available.

You can utilize this AI plagiarism checker in a variety of scenarios, including articles, reviews, posts, and academic papers. To test it out, I copied text from an old GeeksGyaan article on smartphone addiction.

In under 10 seconds, the AI text detection tool analyzed over 600 words and gave me the green light, indicating the text was human-written. I repeated the test with several text excerpts and the tool consistently delivered accurate results.

Writer AI Content Detector

The content detection tool from Writer AI functions similarly to other tools on the market. To use it, simply input your text, whether copied or self-generated, and click “Analyze.” However, please note that the tool is limited to 1,500 characters at a time.

For longer pieces of text, it’s necessary to divide them into smaller parts. Alternatively, users can input the URL of a web page, and the tool will extract the text automatically.

The Writer AI tool employs a percentage meter to determine whether content has been plagiarized. During my testing, I inputted a variety of text inputs, and the tool consistently distinguished between human and AI-generated content with ease. However, for those looking to detect AI-generated plagiarism on a larger scale, it’s necessary to contact Writer AI directly.

Powered by a combination of advanced AI technologies, including machine learning, deep learning, and natural language processing, Grammarly’s plagiarism checker is highly accurate and efficient at detecting copied text.

It’s important to note, however, that Grammarly’s detailed plagiarism statistics are only available to paying customers.

Conclusion

Plagiarism checkers can be useful in identifying instances of AI-generated content that may have been deliberately included in written work.
