6 Best AI Content Detectors (2023): AI Content Detection

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 detectors can spot patterns created by GPT-3 (short for Generative Pre-trained Transformer 3), 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 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 if these tools can detect AI-generated content, Google can also—it’s just a matter of time.

That’s why I’m sharing the best AI content checker tools, 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. Originality.AI

Originality AI detection score and plagiarism score

Originality.ai is an AI detection tool and plagiarism checker integrated into a unique platform built specifically for content marketers and web publishers.

You can detect AI-written content generated by GPT-3, GPT3.5 (DaVinci-003), and ChatGPT. They claim they’re the only tool that can successfully detect AI content. After running a trial, as you can see further below in this article, it’s really the only tool that comes close to a true result.

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

Furthermore, it 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. If they find most of the content was created using AI content generators, they might back off from the purchase.

Key Features Making Originaly.ai One Of The Best AI Content Checker Tools

  • Detectable AI Content – Originality AI can detect AI-generated text and gives you a score from 0% to 100%, comparing the originality of the document and the supposed AI-generated content.
  • Plagiarism Checker – You can write blog posts more confidently and publish them after assessing the plagiarism score.
  • Detect ChatGPT text – ChatGPT is a newcomer in the AI industry. However, because it’s an AI tool that can generate content, it can be deemed suspicious by Google in the near future. Fortunately, Originality AI can also detect ChatGPT-generated text.
  • Unlimited Use – Add unlimited members and scan unlimited websites for human written text and plagiarism.
  • API Access – Integrate Originality.ai with other tools and create custom applications.


Originality.ai offers straightforward pricing.

2. Content at Scale

Content at Scale’s AI detection tool is the best free AI content detector tool available. This free tool can detect content generated by AI up to 2,500 characters (averaging 500 words).

But it doesn’t stop there. Content at Scale is the only AI writing tool that automatically bypasses any AI content detection tool. You don’t have to worry about creating content with AI that might be penalized by Google in the near future.

Moreover, you can produce SEO-optimized 2,600+ word blog posts in a few minutes based on your input keyword. Content at Scale’s AI writer makes it easy to generate articles in bulk so you can gain topical authority fast.

More importantly, if Google detects AI content in the future, you’ll be safeguarded.

3. Writer AI Content Detector

Writer.com AI content detector

Writer.com is a content writing tool that includes many short-form templates for generating different types of high-quality content for website copy, social media, sales pages, ads, and more.

This automated content generator can also create entire blog post drafts and rewrite any sentence to match your style. And because Writer is one of the best AI content generators on the market, it includes a free AI detector (limited to 350 words) that gives you a human content score.

Key Features

  • Free AI Content Detection Tool – You can check for AI-generated content for free but up to 350 words. If you’re writing long-form blog posts, you’d better use Content at Scale.

4. Kazan SEO

Kazan SEO AI content detection tool for GPT3

Kazan SEO is a simple all-in-one SEO tool that’s free to use. It includes an AI GPT3 detector that allows you to check unlimited words for AI-generated content and a few other tools, such as a content optimizer, a text extractor, and a keyword research tool based on clustering ideas.

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

  • AI Content Detector – Analyze any text, no matter how lengthy, and get a score from Real to Fake (human written to AI written).
  • Bulk AI Content Detector – Type in your URLs and analyze them all in one go.
  • Keyword Cluster Ideas – Type in one keyword and get dozens of related keywords to help you gain topical authority.
  • AI-generated Content – Kazan SEO provides a simple AI text generator that reads around 600 characters back from the last character.


Kazan SEO is free to use. You can make AI content detections for unlimited words without paying a dime.

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

5. 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 the detector on your website by downloading the source code from GitHub.


GLTR Test Model GPT-2 AI Content Detector

Developed by MIT-IBM Watson AI lab and Harvard NLP, GLTR can be a fun tool to use if you’re a developer of AI tools. The visual trace of a language model like GPT-2 is examined forensically by this AI detection tool. Unfortunately, it stopped at GPT-2, and it’s unreliable to detect GPT-3 text.

Because a language model can predict the next word in a given context, it’s easy for these AI detection tools to analyze patterns in the automatically generated text.

However, because artificial intelligence is getting smarter, thanks to Machine Learning, AI content detectors must keep up with the pace to spot the difference between AI-generated text and human-written content.

GLTR is open-source, and you can download the source code from its website.

Limitations of AI Detection Tools

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, namely Content at Scale, Originality.ai, Writer, and Kazan SEO. They all came up with different scores.

AI content detectors comparison with GPT-3 text

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

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 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 “6 Best AI Content Detectors (2023): AI Content Detection”

  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.
