8 Most Accurate and Reliable AI Content Detectors in 2023

AI detectors emerged to counter AI-generated content on the internet. Recently, ChatGPT shook the wave of the content writing space, and now a human can almost not tell which content is written by a fellow human and which is generated with AI. For context, Google can detect AI content, even though they claim not to be against AI-enabled written content.

The impact of AI-written content on SEO has not been directly benchmarked by Google, but it presents a more grave issue when it comes to leveraging AI-powered tools to create content – plagiarism. Because AI-powered writing tools are built on top of Large Language Models (LLMs) that have been trained on billions of pages of data in the form of books, news, and articles of the internet, they tend to plagiarise written content.

Despite this challenge, a recent Gartner report forecasts that by 2022, 70% of organizations will be experimenting with immersive technologies, including AI content generators, for both consumer and enterprise use. Another 25% will deploy these technologies in production. 

This leaves no doubt that content marketers have to find ways to strategically leverage AI tools to achieve an optimal mix of efficiency and creativity in content production. At the same time, it’s critical to remember that AI is a tool designed to enhance human creativity, not replace it. For example, tools like Grammarly, OpenAI’s ChatGPT, and Jarvis.ai can speed up the entire content pipeline, from ideation to drafting to proofreading.

The final steps, however, including a deeper understanding of audience needs, creating compelling narratives, and infusing the brand voice, should remain a human task. AI content detectors can help you identify where not enough effort has been put into these “human” phases, helping you craft better content.

Thus, marketers should use AI content detectors to help ensure the quality and uniqueness of their AI content.

This article discusses what AI content detectors are, how they work, their level of accuracy and reliability, and some of the best AI detectors to try out.

What are AI content detectors, and how do they work?

AI content detectors are tools that check for AI imprints in a piece of content. They statistically determine whether a piece of written content was created by an AI or a human. The development of tools like ChatGPT that create well-written content with a well-constructed prompt has made it harder to distinguish between human-written and AI-written content. Hence, the need for AI content detectors has arisen.

To better understand how AI detectors work, it is critical to understand how AI-generated content is created. AI-generated content is produced with Natural Language Processing (NLP) techniques that enable computers to imitate human language patterns based on Large Language Models (LLMs) trained on large datasets. AI detectors work in reverse.

AI detectors (usually AI writing detectors) work with language models that predict the likelihood of a word or phrase being written by a computer in a sentence. Their prediction is used to score how human-like content is.

In short, AI detectors serve as a sort of quality assurance, ensuring that content is original and unique.

How accurate and reliable are AI writing detectors in general?

AI plagiarism checkers and writing detectors have been on the rise since ChatGPT proved its power in the content creation space. With their level of accuracy in question, these AI detection tools have claims to their respective accuracy. Some even boast of 90 percent plus accuracy in detecting AI-written content.

However, the accuracy of these tools is not always foolproof, and they can be bypassed in certain instances. One way in which these tools can be bypassed is through paraphrasing. Paraphrasing can be done by humans, but there are also content optimizers that can help to automate this process.

Another way in which AI detectors can be bypassed is by infusing uncommon words into the AI-written content. This can help to boost the originality of the content and make it more difficult for the AI writing detector to identify whether the content is being generated by an AI tool or not.

That said, while AI writing detectors do very well in detecting the imprints of AI tools like ChatGPT in written content, they are not infallible. It is important to exercise caution when relying solely on their accuracy. They are most effective as part of a robust editorial process that also ensures you maintain the “human touch” in AI-assisted content.

This includes having experienced editors and content strategists review all content before it’s published. You can also establish guidelines specifying how and when AI tools should be used. By making sure humans have the final say, you can ensure that your content retains its authenticity and relevance, no matter how advanced AI becomes.

8 best AI content detectors worth trying

AI should be seen as a strategic partner in content production, providing support, speed, and scale to your team’s efforts. However, in today’s digital landscape, it’s crucial to safeguard your brand’s integrity and credibility. These AI content detectors can help you get the best of both worlds with large-scale efficiency especially when they are used to complement, not replace, human judgment and intuition.

Human-written content

AI-generated content

GPTZero reports two plagiarism indicators in the form of ‘perplexity’ and ‘burstiness’. Perplexity indicates the level of familiarity of GPTZero with the text. This is primarily because GPTZero has been trained on related data. If GPTZero is relatively familiar with the text, it will yield a lower perplexity score. Otherwise, it would yield a higher perplexity score, indicating that the content is more likely to be generated by a human.

The burstiness score compares the variations of the sentences in a text. AI-written sentences vary less in thought flow, scoring lower in burstiness. Humans, on the other hand, write with more variations in thoughts, so the burstiness score of human-written content will score higher.

Features

• GPTZero provides four free text analyses per hour.

Can AI-generated content be paraphrased to pass AI detection?

Yes, but read on.

AI-assisted content writing is slowly becoming a norm as the development of advanced natural language processing (NLP) techniques become more useful. However, the unregulated use of AI-powered writing tools leads to plagiarism and misinformation because AI writing tools rely heavily on existing data on the internet, which means that they can produce content that is similar or identical to existing content.

To bypass AI detection and avoid plagiarism, one option is to paraphrase the content. If done correctly, paraphrasing can significantly reduce the chances of detection by AI detectors. However, the effectiveness of paraphrasing depends on the mode of paraphrasing. If the paraphrasing is done by a human, the chances of detection are significantly reduced. On the other hand, if the paraphrasing is done using AI paraphrasing tools like QuillBot, there is a chance of detection by sophisticated AI detectors like Originality.ai.

That’s why paraphrasing AI-generated content should be viewed as an opportunity to infuse the brand’s unique voice into the content, not just as another obligation to pass off to AI. AI-generators are smart, and getting smarter by the day, but there might still be a disconnect between what it’s capable and its ability to match your brand’s unique voice and meets your audience’s needs. It’s advised to use paraphrasing to bring in the brand’s unique perspective.

Despite the potential benefits of using AI writing tools, it is still important to fact-check the content generated by them before publishing it. This helps to ensure that the quality of the content is maintained and that the content is accurate and less prone to plagiarism and misinformation. By doing so, you can speed up your content creation process while maintaining the integrity of your content.

Evidently, the right usage of AI-powered writing tools can be very beneficial.

Conclusion

The role of AI in content creation is only expected to grow, with a PWC report suggesting that AI could contribute up to $15.7 trillion to the global economy by 2030. 

However, as search engines become more advanced, they prioritize quality, relevance, and user experience. As long as your AI-generated content meets these criteria, you won’t be disadvantaged in search rankings. 

Whatever tools or processes you use to create content, the goal should always be to deliver value to the audience. From that perspective, AI content detectors are just another AI tool to assure quality content, not a threat. Businesses that embrace this philosophy will likely stay ahead of the curve, regardless of how AI evolves in the content landscape. 

To sum up, AI content detectors have come to control the quality of the content produced by AI-assisted writing tools. It is only proactive to get acquainted with AI detectors as a writer, content marketer, or SEO specialist, as more and more writers are adding AI writing tools to their workflow.

This article has discussed how AI writing detectors work from a non-technical perspective and narrowed down reliable and accurate AI detectors to choose from on the internet.
