A few years ago, the idea of AI taking over our jobs seemed like a far-fetched notion — but it’s slowly becoming a reality. Although AI chatbots like ChatGPT were initially created for casual conversations, students are now using AI-generated content to complete school assignments, including copying text from legitimate sources. However, there are ways to detect this plagiarism using AI-powered plagiarism checkers, which can quickly identify instances of copied content. If you’re looking for effective ways to detect AI-generated content, we’ve got you covered. In this article, we’ll explore the top 12 AI plagiarism checker tools that are perfect for identifying ChatGPT and other AI-generated content.

Best AI Plagiarism Checker (2023)

1. Simplified Plagiarism Checker

Simplified AI plagiarism checker operates differently from others. Rather than scanning user inputs, it has the ability to search entire web pages for instances of plagiarism. Specifically, it can search for copies of a given web page on the internet and identify instances of content theft. While marketed primarily as a tool for businesses, a Simplified plagiarism checker can be used to great effect by individuals looking to protect their work online.

AI plagiarism checker is a user-friendly tool that makes plagiarism detection a breeze. Simply copy and paste the content into the writer’s doc, and within a minute, you’ll be provided with detailed, Google-like results that specifically highlight any instances of copied content. The results even include the word count and percentage of copied content. While extremely accurate in detecting AI-generated text, the service is currently free to use, though it may potentially become paywalled in the future.

2. OpenAI Text Classifier

To combat the rising issue of AI-generated content, OpenAI — the company behind ChatGPT — has released an AI plagiarism checker called the AI Text Classifier. This finely-tuned GPT model is designed to predict the likelihood of a given text being written by a human or computer. The ability to instantly spot instances of AI-generated content and take the appropriate actions to assure originality and authenticity makes it a potent weapon in the fight against plagiarism.

The AI plagiarism checker has undergone training using a range of input sources, both human-written and AI-generated. This enables the tool to easily flag instances of plagiarized AI text across all types of written content. While OpenAI acknowledges that the tool is still a work in progress and not entirely infallible, my own tests — including copying my own Beebom article and text from Wikipedia — showed that it can effectively identify human-written text. This free-to-use AI plagiarism checker is one of the best available, although it does require a minimum input of 1,000 characters.

3. Copyleaks AI Content Detector

Copyleaks claims that its AI-powered plagiarism detector can identify content created by either humans or AI with 99.12% accuracy. The tool supports multiple languages — including French, Spanish, and German — and relies on an innovative ‘fight fire with fire’ approach that uses AI to detect AI-generated text. This enables the tool to keep pace with the latest AI chatbots and remain effective at identifying AI-generated content. Copyleaks even plans to support ChatGPT 4 when it becomes available, making it a versatile and forward-looking solution for detecting plagiarism in all types of written content.

You can use this AI plagiarism checker for a range of use cases, from articles and reviews to social media posts and academic papers. I tested the tool by copying text from an old Beebom article about smartphone addiction, and in less than 10 seconds, the AI detection tool verified that the text was human-written. I also tested it with various other text excerpts and found its accuracy to be reliable.

4. Content at Scale

Thanks to its advanced training on billions of pages of data, Content at Scale boasts an impressive ability to accurately predict the most likely word choices. As one of the top AI plagiarism checkers available, it uniquely leverages a proprietary content generator that taps into multiple layers of AI components to efficiently scour all kinds of AI-generated texts. With this approach, Content at Scale can identify instances of plagiarism across various platforms, including the latest chatbots such as ChatGPT.

To put this tool to the test, I mixed some of my own writing with ChatGPT-generated text and ran it through the AI plagiarism checker. The tool meticulously scanned the entire content and identified the different sources of AI and human output, highlighting them in three distinct areas — predictability, probability, and pattern. Notably, the tool demonstrated impressive accuracy in detecting plagiarism, even when some of the text was written by me. As previously mentioned, it is free to use, so give Content at Scale a try and see for yourself.

5. Writer AI Content Detector

Similar to other online services, Writer AI offers both AI-generated writing options and plagiarism detection tools. However, its plagiarism detection tool is particularly effective at identifying copied content. The tool is user-friendly and even has plans to release a dedicated app for the company’s other services.

The Writer AI content detector works by allowing users to input their text or copied content and click on the Analyze button. However, the tool is limited to 1,500 characters at a time, so larger pieces of text need to be divided into parts. Alternatively, users can input a web page URL to extract the text. The tool uses a percentage meter to determine the level of plagiarism. In my test using a few selected inputs, the tool was able to accurately distinguish between AI and human-written text every time. For those looking to detect AI-generated plagiarized content on a larger scale, they will need to contact Writer AI.

6. Grammarly

Grammarly offers a simple and effective approach to checking for plagiarism, despite being typically thought of as a grammar-checking tool. The program uses a variety of AI techniques, including as machine learning, deep learning, & natural language processing, to both enhance writing and detect instances of plagiarism.

It should be noted that Grammarly’s detailed plagiarism analysis is only accessible with its $12 monthly premium edition. Users’ access to comprehensive plagiarism statistics using the free version, which only shows whether plagiarism has been detected, is therefore restricted. But in my testing, I discovered that Grammarly was capable of identifying instances of plagiarism in addition to other writing problems.

Stay Ahead of ChatGPT with These Top AI Plagiarism Checkers

I hope these AI-driven plagiarism checkers prove useful in detecting any sneaky instances of plagiarized or ChatGPT-created content. With the increasing reliance on AI-generated text, such detection tools will become more important for teachers and academics. However, for those who are curious about AI’s capabilities, there are plenty of cool things to explore with ChatGPT.
