AI-generated content is taking the Internet by storm. With so many AI content creation tools around, it’s getting easier than ever for content creators to produce text quickly. However, the best AI content detection tools can spot patterns created by GPT-4 (short for Generative Pre-trained Transformer 4), the model used by most AI writing tools.

The question is simple: Why should you use AI detection tools if you’re using AI-written content? And should you be worried? Moreover, can Google detect AI content?

The truth is that employing AI-generated content on your website to manipulate rankings is strictly forbidden under Google’s webmaster guidelines.

While in the past, detecting AI content was nearly impossible, today, there’s a growing number of AI detection tools (and many ways to bypass them, including AI humanizer tools). And if these tools can detect AI-generated content, Google can also—it’s just a matter of time.

Additionally, some companies have developed undetectable AI content writing tools to help you craft great content without being flagged as written by a robot.

But in this article, I’m sharing the best AI content detection tools for publishers (and also teachers), so you can futureproof your website content and not risk your rankings on search engines.

What Are The Best AI Content Detectors?

Here’s a list of the best AI content detection tools you can use today.

1. Winston AI

For now, the tool only supports English and French languages.

  • Document Support – The tool supports the most popular text and image formats, such as DOCX, PDF, JPEG, and PNG.

The integrated plagiarism checker at an affordable price sets apart from other AI content detectors. You won’t go bankrupt because checking every 100 words only costs $0.01.

Furthermore, the AI content detection tool allows you to make a full site scan. This is an invaluable tool for website buyers, who can now check the percentage of human-generated content on a website.

  • API Access – Integrate with other tools and create custom applications.

What sets Kazan SEO apart from other AI content detection tools is its ability to make analyzes in bulk. You just have to input all URLs in a text box and hit “Detect Urls for AI Content.”

Furthermore, if you only input the homepage of a website, Kazan SEO will fetch the first 100 top results from Google and detect them.

Key Features

However, don’t use it for generating text, as many free AI writers out there do a better job at that. And if you want to automatically generate long-form text that bypasses AI content detection, use Content at Scale.

10. Hugging Face

Hugging Face Open AI Detector

Hugging Face is the central hub for developers to collaborate, explore, and experiment with Machine Learning. The open source Machine Learning movement provides many developer tools to experiment and take artificial intelligence writing to a new level.

Of course, they had to have an AI detection tool. However, it was built by OpenAI and only supports GPT-2. Moreover, they explicitly say not to use it for detecting ChatGPT.

The tool provides a score from Real to Fake (human to AI), and it’s best suited for lengthier content.

You can use this free AI detection tool on your website by downloading the source code from GitHub.

Limitations of AI Detection Tools

Do AI content detectors work? Well, that’s a question with a puzzling answer.

Because this technology is still new, the best AI content detectors may have limitations, making it hard to settle for a score.

For example, I analyzed an article written by an AI writing tool on different AI content detection tools: Content at Scale,, Writer, and Kazan SEO. They all came up with different scores.

AI content detectors comparison with GPT-3 text

In the above example, is the only AI content detection software that comes closest to the true result, returning an AI score of 49%. All other AI content detector tools assume the content was written by a human when it was not.

I put the same text through Winston AI, which returned a 69% human score.

Winston AI analysis result from AI written content

While these tools can identify potential AI-generated content, they can only speculate as to whether or not the content was actually created by AI.

Furthermore, if you make a few spelling errors, AI-written content may be scored as human-written text. This makes the whole process worthless.

On the other hand, Content at Scale is the only AI tool on this list that can generate AI content that bypasses AI content detectors, making it an invaluable tool for digital marketers.

While you still can’t rely on these tools to check for AI-generated content, they’re a good start to futureproof your website content.

Can Google Detect AI-generated Content?

If you’re reading this article, you may be asking yourself if Google can detect AI-generated content or not.

There is still a lack of clear information since relevant technologies have not advanced sufficiently.

However, Google’s Search Advocate, John Mueller, clearly states that AI-generated content violates Google’s guidelines. Not only that, but if the webspam team were to see it, they would immediately label it as spam. As a result, it wouldn’t appear on the search results pages (SERPs).

If you’re a website owner or have online businesses relying on web content, you shouldn’t take this information lightly. While Google is not yet completely effective in detecting AI content, the future will bring new algorithms to fix that.

If you don’t want the risk of having Google detecting your content as AI (or worst, as spam), be sure to take the proper measures by ensuring all your content is human-written. Or at least, if you’re using AI writing tools, don’t just copy and paste the generated content—putting your own twist on it and making adjustments will help make it more unique.

After all, we all want to see content on the web that’s relevant and of high quality, right? What’s your take on the subject you’re writing about? What’s your experience with it? That’s what the reader wants to know. And this goes back to Google’s Helpful Content Update in 2022—eliminating keyword-stuffed articles that have no function other than to boost the author’s search engine rankings.

Best AI Content Detection Tool: That’s a Wrap!

Digital marketers have been using AI content writing tools such as Jasper AI, Copy AI, Anyword, Article Forge, and others to create content for their online businesses in the past few years.

However handy, these tools are merely assistants. The content created by these AI platforms shouldn’t be copied and pasted just as they are. As AI-detecting algorithms advance and Google starts identifying them as spam, many websites that have emerged in the last couple of years and use these technologies to create dozens of articles per day may see a looming day in the near future.

Be sure to futureproof your content with these best AI content detectors.

4 thoughts on “10 Best AI Content Detection Tools and ChatGPT Checkers You Should Try”

  1. I really don’t think that these detection tools are reliable at all.
    Using the same text in various tools, I get even totally opposite results.
    Some would claim it’s 100% AI-made
    Others would claim it’s 100% human-made
    And some would say something in between.

    I don’t think that these tools should be used at all, as they are confusing and full of errors and mistakes. They surely cannot be relied upon.

    • These AI content detection tools are still in their infancy. Also, Google has declared that AI-generated content is against their guidelines; thus I think these tools will be improved to be more precise since GPT-3 technology contains patterns that can be identified.

  2. I don’t think so orignality.AI is also reliable! I have written an article that is 100% human written as there was no use of AI at all, but, when checked by orignality.AI it was 51% original and 49% AI content with 0% plagiarism. There is no proof of which content is AI based. This is quite disturbing thing for writers as their abilities are being underestimated just because of these detectors!

    • These detectors leave much to be desired! Let’s see what Google comes up with in the future regarding AI-published content.
