The Best AI Content Detector Tools Compared

AI Content Detector Tools

We’ve compiled a list of the best, most prominent AI content detection tools. You can jump straight to that list now if you’d like.

AI Content Detectors are on the rise. Understand how they work and ensure that your content can pass their reviews.

AI Content Detectors are built to identify repetitive phrases and sentence patterns through programmatic tokens. To avoid detection by GPT detectors, it’s important to vary your word choice and sentence structure in your writing. Also be sure to focus on incorporating interjections, metaphors, and colloquialisms can also help make your writing more varied and less likely to trigger a detection flag.

If you’re like me, you may want to learn a little about AI content detectors, why they matter, and how they work… before you start diving into specific tools.

AI content detection is a rapidly growing field. And it clearly has the potential to revolutionize the way we consume and create content. And with the proliferation of AI-generated content, it’s becoming increasingly important to be able to accurately detect and identify it.

Why would we want to detect it? A few key reasons stand out…

  • Websites looking to rank content in Google are definitely going to want to make sure their content is not identified as AI generated content. …because all signs point to the likelihood that Google will be looking for AI generated content, and de-valuing it. But there is also strong evidence to support the fact that ultimately, if content is deemed to be useful and helpful to the reader, Google may not care whether it’s written by a robot or a human. So if it IS written by AI, you’re going to want to make sure it’s edited by a human to ensure it is good, useful, and has that hard-to-identify personal touch.
  • Content publishers may want to make sure that writers they are paying to, you know, “write”, are in fact actually writing… and not just submitting AI content.
  • Teachers are going to need tools to determine if work submitted by students is actually their own, well, “hard work”, or if it’s something they generated in a couple of minutes with an AI tool.

AI Content Detection Tools

Your Brain

That’s right, you can likely spot some AI content just using the old noggin! Here are a few key strategies that can help you identify AI-generated content on your own:

  1. Look for repetitive or formulaic language: One of the key characteristics of AI-generated content is that it can be repetitive or formulaic in nature. If you notice that a piece of content is repeatedly using the same phrases or structures, it’s a good indication that it may have been generated by AI.
  2. Check for unnatural or awkward phrasing: While AI content generation systems have come a long way in recent years, they still struggle to replicate the natural flow and phrasing of human language. If you come across a piece of content that feels awkward or unnatural, it’s worth considering the possibility that it may have been generated by an AI. This may be in for form of a single word that seems misplaced, a point or topic that is essentially repeated later in the content, or a phrase that just seems “off” and unnatural to the way we typically write and speak.
  3. Check for a lack of originality: Another key characteristic of AI-generated content is that it can be difficult for it to be truly original. If you come across a piece of content that seems to be a copy or paraphrase of something else, it’s possible that it was generated by an AI.

In addition to these strategies for detecting AI content on your own, there are also a number of specialized AI content detection tools that can help you identify AI-generated content. These tools often rely on machine learning algorithms to analyze the structure, language, and style of a piece of content to determine whether it was likely written by a human or an AI.

Top Choice

AI Content Detection – Content at Scale

This free AI content detector from Content at Scale allows you to paste in your content, which it then scans and quickly returns a percentage on a scale from % Real to % Fake, where fake is AI generated.

It can detect AI content from the latest language models – GPT-3, GPT-3.5, and ChatGPT

This is my top choice as a detection tool because Content at Scale has the most sophisticated AI content creation tool… therefore it stands to reason that their detection would be as sophisticated. Plus, I’ve tested it with real and AI content, and gotten very accurate detection results.

AI GPT3 Detector – Kazan SEO

Like all tools from Kazan SEO, the AI GPT-3 Detector is free. I don’t think there is a limit to the length of text you can paste into the tool for analysis. This tool currently only seems to support the GPT-3 language model. But that’s what many of the popular AI writing tools are based, on, so it’s a solid tool. Especially considering it’s non-existent price!

Plagiarism Checker and AI Detector –

The tool is unique in that it is both a plagiarism AND AI detection tool. So it can identify if content was copied from somewhere else on the Internet, whether it was written by a human or a machine. In other words, it can help identify if text or other content has been copied from another source without proper attribution. Plagiarism detection tools can be used to check the originality of written work, such as academic papers, articles, or website content. Unlike AI detection tools, they typically work by comparing the text being checked against a database of known sources, such as published articles or websites, to see if there are any significant overlaps. If the tool identifies any overlaps, it may flag them as potentially plagiarized content.

And of course, it can detect if ‘original’ content was written by a machine. It’s based on the latest language models. GPT-3, GPT-3.5, and ChatGPT.

GPT-2 Output Detector Demo – Hugging Face

Hugging Face seems to be a well known player in the space of AI content detection. I suspect that’s because they have been around for a while… relatively speaking. But while they are well known, they do not seem to be as up to date as some of the other tools in our list. They seem to only support GPT-2. So content written with newer models my slip through their radar.

On the plus side, the tools is dead-simple to use, and it’s free. Hugging Face also has a strong machine learning community if you’re into that sort of thing.

AI Content Detector –

Like Content at Scale, offers AI content writing tools. And similarly, it has a free AI detection tool. Presumably to help bring in more potential customers. Smart play if you ask me.

The tool is easy and intuitive, and like it’s competitors on this list, it supports GPT 3, GPT 3.5, and ChatGPT language models.

AI Content Detector – Crossplag

And finally, we have yet another AI content detector. This one is from Crossplag. I don’t have a ton of detail about this one, but here’s what I CAN tell you.

I tested it with some content written by ChatGPT, and it accurately detected it as written 100% by AI. It’s also free and simple to use.


You would think that Google would have an AI content detection tool or two, wouldn’t you?

Well the sad excuses I found for publicly available tools were not great. So much so that I left them off of this list.

That being said, you can bet that Google does have some sophisticated detection methods behind the scenes. They are likely already scanning for and factoring AI written content in their search algorithms. And it kind of makes sense that they wouldn’t want the public messing around with those tools.

So there you have it. AI content detection is an important area of focus for many businesses and organizations, especially as AI-generated content becomes increasingly prevalent online. And by understanding how to detect AI-generated content and using specialized tools like the GPT2, 3, 3.5, and so on… detectors, you can ensure that you’re accurately identifying and labeling AI-generated content and making informed decisions about how to use it. And that’s the key, you know!?

In addition to helping you identify AI-generated content, these tools can also be useful for those who are looking to use AI-based content creation to improve their SEO (search engine optimization) efforts. By leveraging the power of AI to create high-quality, relevant content, businesses can increase their visibility in search engine results and drive more traffic to their websites.

To Conclude

AI content writing is a rapidly growing field that has the potential to literally revolutionize the way we consume and create content. With the help of tools Content at Scale’s AI Content Detection, businesses and individuals can fairly accurately identify and label AI-generated content and determine the best course of action from there.

Remember this! Whether an AI detection tool indicates that content is written by a human or a machine, these tools are not completely reliable. They sometimes get it wrong. So use that big brain of yours to make the final determination as to whether a piece of content is actually useful or not. If it is, do we really care how it was written… or would Google care either?
