The rise of ChatGPT and other similar AI content generation services has forced the education industry to undergo major disruption! In a world where AI content is easily accessible, common assignment patterns will no longer work. Students can now easily write their assignments and submit them as their own using these services. As a result, a shift in traditional assignment patterns is required. This is not, however, a task that can be completed quickly. Teachers are not yet ready to make such a significant change. The education industry as a whole is stuck in its current mode of operation. As a result, AI content detection tools for teachers are in high demand right now. In this blog article, we will explore some of the best free AI content detection tools for teachers. So, let’s dive right into it.
AI Text Classifier
AI text classifier is the response of Open AI, the same company responsible for launching ChatGPT. Soon after launching ChatGPT, they realized the need for an AI content detection tool. It is especially desired by academicians and researchers to avoid plagiarism and protect originality. AI text classifier requires about 150 to 250 words to try and detect the originality of the content. Also, it is important to keep in mind that the AI text classifier is limited to English content as of now.
To use the AI text classifier tool, simply copy and paste the text into the box. Then click the submit button and the tool will show the result as “very unlikely”, “unlikely”, “unclear if it is” or “likely” AI generated. The tool can fail to determine whether the text is AI generated or not if the text is modified to some extent. They also acknowledge that the detection may not be 100% accurate and sometimes it can mislabel both AI generated and human generated content. This AI content detection tool is free to use so it is a good thing for teachers.
Copyleaks AI Detection Tool
Copyleaks is usually known as a plagiarism checking platform. Recently with the growing demand for AI detection, they have released a beta version of the Copyleaks AI detection tool. While their plagiarism checking platform is premium, their AI detection tool is completely free. It works similarly to the AI text classifier where you just copy and paste the text into a text box. Then click on the check button to verify whether the text is AI generated or human generated. It does not show any score and directly labels the detection as either AI generated or human generated.
Copyleaks claim to successfully detect AI generated text of multiple languages with 99.12%. However, from what we found it can easily be deceived with simple paraphrasing of the text generated by AI content generation tools. So, it can be useful for detecting direct copies of AI generated content only. What is Good here is that they have also released a browser extension for Chrome and their plagiarism checking platform is also integrated with the ability to detect AI generated content. So, you have more flexibility to detect AI generated content using the browser extension or integrate their service through popular LMS platforms.
Writer AI Content Detector
Writer is a content generation service as well but they have also stepped into the service for detecting AI content detection. The Writer AI content detection part of Writer is also free to use. The tool provides you a score in percentage to reflect on whether it is AI generated or human generated. Writer is somewhat more accurate in detecting AI generated content compared to other tools mentioned above. Even if you paraphrase or modify the text a bit. So, it is a good option for educators if they wish to detect AI generated content in student submissions. To use it, you can copy and paste the text into a text box in the tool. Additionally, you can copy and paste a link to content that is available online and use the tool to scan and detect AI generated content. Pretty useful for a free tool!
Content At Scale AI Detector
The Content At Scale AI detector is a powerful free AI detection tool for teachers. The interface is similar to other AI content detectors. At the same time, it is really powerful and accurate when it comes to detecting AI generated content. It is hard to avoid AI detection unless you overly modify the AI generated content. So, teachers can easily identify most of the AI generated assignments or works submitted by the students using this tool.
As a scan result, it shows both a percentage of the detection and a label in bold font. We have tried several texts generated by AI and modified them to some extent. However, this tool was really quite accurate in detecting that the text was AI generated. The score may vary depending on the level of modification but it still successfully detects the AI generation. So, teachers and institutions can easily use this tool confidently to identify AI generated content. The tool was the top AI detection tool for educators until the next AI detector tool featured in this blog entered the picture.
ZeroGPT AI Content Detector
ZeroGPT is also a very good free AI content detection tool. It comes with a simple UI. There you can just paste your content or upload a file to start the AI content detection process. Besides, the tool claims to deeply analyze the content to detect whether it is AI generated or human written by running multiple algorithms based on different research papers.
It shows the result in a gauge along with a score in percentage and a verdict. It also shows the texts it thinks are AI generated in yellow marks. There seems to be no limitation on the content scale. So you can check long content and get results without any issues. One more good thing about ZeroGPT is that it can provide APIs for organizations or institutes if they want to utilize ZeroGPT on a mass scale.
GPTZero AI Content Detection Tool
We saved the best one for the last! The GPTZero is a free AI content detection tool especially created for educators. They seem to understand the teachers’ struggles well. It seems they have given their best efforts to make sure that the teachers can identify AI-generated content easily no matter how crafty the student is. It gives the teachers an option to copy and paste the text or upload documents so that they can scan the works of students without any hassle.
The result is very accurate even with heavily modified content. It even highlights the lines that it detects as AI generated. This becomes easy for the teachers to refer to when the students submit AI generated work. What is best is that you can use the platform to upload a bulk amount of files at once to scan for AI detection! Just what a teacher needs, won’t you agree? Therefore, this is for now the best option a teacher can get for identifying AI generated content in student assignments or assessments.
What AI Content Detection Tools for Teachers Can Do?
AI content detection tools can help teachers identify whether the submitted content by the students is generated using AI content generation tools or not. This will help them to temporarily tackle plagiarism issues caused by the massively open AI content generation tools. Also, this provides them with enough time to plan a better strategy to incorporate new assignments and assessment techniques.
This is especially important to consider, as the use of AI content generation tools such as ChatGPT can make it easier for students and learners to produce work without fully understanding the concepts they are studying. Without caution, they can become too reliant on these tools and lose the necessary grasp of the basics. Therefore, it is vital that those using ChatGPT and similar AI content generation tools are aware of how to use them responsibly.
How Do AI Detection Tools Work?
AI content detectors use language models like those employed by Google to assess the probability of certain words and phrases appearing in the content. This makes it possible to give users a rating of how closely the material resembles content written by a human. To do this, the software scans the words and syntax of the text, looking for any repeated patterns. If the detector finds patterns commonly seen in AI-generated material, it flags the content as AI generated content.
These tools likely rate the text based on its capacity for random, creative words, as opposed to the more predictable, repetitive words frequently seen in AI-generated content. Some of these detectors give a score between 0 and 100. Others simply let you know whether the text is likely AI generated or not. Some even show AI generated content as fake content.
Can AI text be detected?
Yes, Suppose anyone directly utilizes any text that is generated from any of the common AI content generation tools like ChatGPT. In that case, it is highly possible that you can use an AI content detection tool to detect the AI generated text. But, as AI is evolving, the quality of AI generated content is getting better. Besides, if someone utilizes AI content generation tools to generate the base text and modifies the texts either by paraphrasing or manually, it will be difficult to detect the AI generated content.
However, recently Open AI declared that it wouldn’t be a good idea to depend on AI detection tools too much and instead, it is best to utilize your own critical thinking and judgment to determine if the text is AI generated or not. More about it can be found in our blog post titled, “Why You Shouldn’t Trust AI Detection Tools to Spot AI Writing“.
To sum up the discussion, there are now multiple free AI detection tools for teachers. All of those tools can pretty accurately detect direct texts that are generated using ChatGPT or similar AI services. However, some may not give 100% accurate results in detecting AI generated content. It also depends on how much human modifies the text after it is generated. Still, our final verdict is that GPTZero is for now the best free AI detection tool for teachers. Simply because it gives the option to upload a bulk amount of files and is highly accurate compared to the other available free AI detection tools. However, there are some premium tools that might perform better in some cases but that is perhaps a point to be discussed later on. Hopefully, the article could help you identify the best AI detection tools you can use for free.
