Creating original content that stands out from the competition is vital for a content writer or digital marketer. However, in today’s digital world, with AI content writing tools now in the mainstream, it can be hard to make sure that your content is 100% original and free from plagiarism. Fortunately, the best AI content detector tools can help you ensure your blog posts or articles are original content written by a human.

Previously, AI content was poorly written and easily distinguished compared to human writing due to its poor quality. However, recently tools such as OpenAI’s ChatGPT and Jasper AI have made it harder to tell the difference between AI-generated content and text as the quality continues to improve, even when side by side with human-created content.

It’s now more important than ever to detect AI-generated content before it gets published and distributed. But, unfortunately, this can hurt your brand’s reputation – especially if plagiarised.

To do so, you must have the right AI Content Detector Tools. So you can ensure your business stays ahead of the curve to detect AI-generated content.

In this blog post, we’ll look at the five best AI content detection tools available today to help you find the best one for your needs so that you can future-proof your content and protect it as more AI-generated content is published in 2023 and beyond.

Best of all, it is a free tool to encourage discussions on AI literacy.

The AI Text Classified Model was trained on human-written text. Each document is categorized as either being likelypossiblyunclear if it isunlikely, or very unlikely AI-generated text.

As it is a brand-new tool, there are currently some limitations, such as:

  • It isn’t always accurate and can sometimes mislabel human-written and AI-generated texts.
  • AI text can be edited to beat the content detection tool.
  • It is inaccurate for text written in other languages besides English or by children.

AI Content Detection Test 

OpenAI AI text checker results

I used Jasper to generate over 1000 characters of AI content. However, according to the classifier, the text was ‘very unlikely AI-generated,’ This shows that the tool is still not always accurate and can mislabel AI and human-written content, as advised in the current limitations.

What Are AI Content Detectors?

AI Content Detectors are software tools that use advanced algorithms to help users detect AI-generated content written by AI programs, such as ChatGPT or Jasper before it gets published and distributed. 

They use advanced technologies such as machine learning and natural language processing (NLP). This helps to determine whether your content is original, plagiarism-free, and human-written or. AI-written.

These tools are best used to verify the originality and authenticity of content, such as blog posts, articles, website content, books, or student essays. 

AI content detectors help businesses maintain a high standard of quality for their content, which will help ensure their credibility within the digital space. They also assure companies will avoid copyright or legal issues arising from plagiarised AI-generated content.

AI Content Detectors can also be used by students and educational institutions to verify the authenticity and originality of student essays and assignments.

The best AI detection tools are 94% to 99% accurate in detecting plagiarism, support multiple languages and offer API integration for easy implementation into existing platforms.

How Do AI Detection Tools Work?

AI detection tools use sophisticated machine learning algorithms and natural language processing (NLP) to scan text for signs of plagiarism or potential use of AI-generated text. 

They compare the text with existing online sources to detect statistical patterns usually only seen with AI-created content. The features AI content detection tools analyze include the use of language, sentence length, frequency of phrases or specific words, syntax, and the emotion used.

This comparison allows it to detect potential plagiarism and determine whether the text was written with an AI tool like ChatGPT or by a human.

With best-in-class accuracy rates ranging between 90 – 99%, AI content detectors are ideal for quickly checking large amounts of content in one go before publication and ensuring that all texts remain original and trustworthy. While the technology still can’t identify AI-generated content 100% of the time, machine learning algorithms are rapidly improving, and the results are becoming more accurate.

My Experience Using AI Content Detectors

For years, anytime I write content for blog posts, articles, or websites, I always use Copyscape to check that my content is original, duplicate-content free, and passes a plagiarism check.

Now, I have also added an extra check. I also check for AI content detection with Content At Scale.

It is important to remember that the AI content detector results aren’t always 100% accurate. 

They sometimes mistake human content for AI-generated content. Still, it indicates whether my content sounds original and human-written rather than AI-generated and without emotion.

This helps me determine whether I should change any sentence patterns and if my phrasing is unnatural or constantly repeats identical words. 

It allows me to ensure that my content is well-written, clear and concise, and easy to read. It can also help me write in a better tone of voice. Grammarly is also an excellent tool that can help you to improve your grammar. 

AI Content Detection Tools FAQs 

Can AI Content Be Detected?

Yes, AI content can be detected. AI has become an increasingly popular tool for creating content with the explosion of ChatGPT in the mainstream. But, it is also now possible to detect when content has been generated by AI. 

Artificial intelligence algorithms are becoming more realistic and can generate content that can imitate a human writing style. However, the easiest way to detect AI content is through natural language processing (NLP) techniques. 

NLP algorithms analyze text for patterns that indicate when a machine has likely generated it. This process can also determine the AI-generated content’s quality and potential plagiarism or copyright issues. 

As artificial intelligence technology continues to advance, it will become easier and more reliable to detect AI-generated content.

How Accurate Are AI Content Detectors?

AI content detectors are highly accurate and reliable in detecting plagiarism, AI-generated content, and content published elsewhere on the web. 

They use sophisticated algorithms to accurately analyze text to detect any content that has been plagiarised and whether it was written by a human or AI-generated. This ensures you can be confident when you publish content that it is original and plagiarism-free.

These tools utilize machine learning technology to continually refine their accuracy levels over time. As such, they provide industry-leading accuracy and reliability when it comes to detecting plagiarism or AI-generated piece of content.

Although no AI content detector is perfect, they sometimes make mistakes and aren’t always 100% correct. The best tools are between 94% to 99% accurate. 

What Is The Best Free AI Detection Tool?

Content At Scale is the best free AI detection tool because it provides quick and accurate analysis of AI-generated text with the best accuracy and efficiency. In addition, the AI Detector gives a Human Content Score out of 100 and a predictability, probability, and pattern score. 

It also highlights the text suspected of being from an AI writer like ChatGPT or GPT-3 generated, so you can revise it.

Best of all, Content At Scale has a 25,000-character limit, unlike other free AI detection tools with much smaller limits.

Can Google Detect AI-generated Content?

Yes, Google can detect AI-generated content. Google uses sophisticated algorithms and AI technologies to detect plagiarism and AI-written content. It analyzes patterns and the text structure typically used in AI-generated content.

With the emergence of ChatGPT, Google has made it a high priority to develop advanced AI detection tools. This includes content generated by ChatGPT, Jasper AI, and other AI content writing tools.

While it is still early for AI detection, the algorithms are not very advanced. So, it is still unclear if Google can accurately identify AI-generated vs. human-written content.

However, the technology is likely to improve over time, but so are AI content tools, which means it may become more challenging for Google to tell the difference.

Should I use an AI content detector?

Yes, you should use an AI content detector. An AI content detector lets you quickly and accurately scan for plagiarism or copyright infringement while ensuring your website is free from AI-generated text. 

With AI writing now in the mainstream, an AI content detection tool is necessary, just like a plagiarism checker like Copyscape. It will help to ensure you only publish high-quality, original, human-written content.

With the best AI content detectors providing advanced scanning capabilities and intuitive user interfaces, keeping your site safe from unwanted automated content has never been easier. So take the extra step towards protecting your business and brand by investing in an AI content detection tool today.

Final Thoughts

AI content detection tools are becoming increasingly important as AI-generated text becomes more and more prevalent. 

With ChatGPT now in the mainstream, the internet is about to become flooded with AI-written content. With these best tools, you can ensure your content and brand stand out while protecting your work from plagiarism.
